Description

ANTITRANSPIRANT COMPOSITIONS BASED ON WATER, QUICK DRY AND NOT STICKY Field of the Invention The present invention relates in general to the field of antiperspirants and deodorants to reduce and prevent perspiration and the body odor associated with human perspiration, particularly the bad odor of the armpits, without the disadvantageous effects of stickiness or moisture following the application.

Background of the Invention • The antiperspirants fight the bad odors of the armpits by inhibiting perspiration through the action of astringent salts such as aluminum and zirconium salts. As has been experienced by a considerable number of users of the antiperspirants, such active salts can be irritating and painful to the skin or body surface to which it is applied in the first place. Deodorants, on the other hand, prevent objectionable odors that result from the degradation of Ref. 25309 components of the sweat which are attacked by chemical substances and microbes, for which they produce fatty acids of bad odors. Because deodorants do not inhibit sweating, but rather inhibit the growth of microorganisms that cause bad odor, deodorants are generally less irritating to the skin than antiperspirants. However, the action of antiperspirants reduces or prevents moisture and sweating; therefore, antiperspirants are frequently preferred over deodorants. To be effective inhibitors of underarm sweat, antiperspirant salts, which comprise antiperspirants, should be used in high concentrations in the products. These water-soluble salts, in concentrated solutions, are astringent when applied to the skin, and sticky when dry, thus producing an unpleasant sticky feel in the armpits. A variety of product forms have been developed with the sole purpose of solving this problem elegantly.

Originally, solutions for spraying in oppressible bottles were sold, but these were wet and dropping drops of the solutions and reduced little stickiness in the armpits. The creams were less sticky, but required manual application and They left unpleasant looking residue on skin and clothes. The rotating bead emulsion lotions were an improvement, because they were applied directly and provided a thin film of the product, but they were still sticky, dirty or scrambled, and slow drying. In addition, aerosol spray solutions appear to provide an elegant product form, but they supplied a spray, broadly diffused, around the user's face and ultimately were rejected because of the negative environmental impact of the spray. His properties. The stickiness was eliminated by the development of antiperspirant salt suspensions, either in a liquid volatile silicone vehicle applied as a solution for a rotating ball device or in a solid greasy bar that can be rubbed in the armpit area. These forms still have some significant degree of acceptance by the consumer, but they are being rejected by many consumers, particularly women, because of the pulverized, white residue, which is both formed and deposited in the armpit area. This factor is particularly objectionable, since the residue is easily transferred from the armpit and is applied to and visible on the user's clothes while the user is wearing the clothes. The high level of popularity of clear antiperspirant forms attests to the importance of the non-elegant and negative effects mentioned above in the mindset of consumers. However, the development of clear antiperspirant products that are aesthetically pleasing have also evaded the formulator. Common clear products use solvents, cosolvents, and emollients that actually increase the adhesion of the solutions of the antiperspirant salts. Those that are commonly used are water-soluble glycols, such as glycerin, propylene glycol, and sorbitol, or ethanol-like solvents, all of which lead to products that are adhesive and sticky in the armpits, and many of which leave Objectable white residues when they dry. In addition, a number of antiperspirants formulated as high viscous internal phase emulsions or microemulsions and comprising oil-in-water compositions and various additives may show a residue. white after application of the antiperspirant and drying. Such a residue can be attributed to the volatilization of the liquid component, which is usually ethanol at high levels, and fact that leaves a film of non-volatile powdered ingredients underneath. Another problem in the art, especially with those antiperspirant compositions having a significantly elevated alcohol content, is an itching sensation which occurs after application of the product on the skin, particularly after shaving. Clear, or translucent, gelled antiperspirant sticks, which are substantially anhydrous, contain an active antiperspirant material, a stabilizer as an essential component, and are gelled in a gelling agent, such as dibenzylidene monosorbitol acetal, have already been described (US Pat. No. 5,376,363 to AJ Benfatto et al.). However, acetal gelling agents are frequently unstable in the acidic environment of most antiperspirant actives, so suitable buffering or stabilizing agents should be discovered and used to stop the acid attack on the gelling agent. In addition, many of the clear or translucent antiperspirant sticks containing the acetal gelling agent and the solubilized active antiperspirant material have the disadvantage that they are inherently tacky. To further complicate the problems in the art, acid hydrolysis of the gelling agent conventionally used occurs more rapidly in aqueous solutions, so that those skilled in the art have had to use non-aqueous formulations. Other compositions provide antiperspirant active materials in gelling agents of different types, such as the polyamide gelling agent (U.S. Patent No. 5, 500, 209 of M.S. Mendolia et al.). Accordingly, there remains a desired goal in the art for the development of stable, clear antiperspirant products, which provide the following advantageous characteristics: 1) that they do not feel objectionably wet or cold during application; 2) they dry quickly; 3) that do not feel sticky or adherent; and 4) that they do not leave visible residues in the armpit area after the application. The present invention provides fully soluble water-based antiperspirant compositions which can be formulated in all types of liquid delivery or dosage forms. The antiperspirant compositions or formulations of the invention comprise newly discovered classes of emollient solvents that are stable, safe for application to human skin, and uniquely satisfy the criteria described above. The present compositions provide formulations Cosmetically elegant, clear antiperspirants, which are aesthetically acceptable after application, which are not irritating to the user's body and skin, and which are capable of effectively inhibiting perspiration and preventing moisture and odor from the body.

Brief Description of the Invention The present invention provides simple, water-based antiperspirant compositions comprising, in general, one or more antiperspirant salts, polyglycols, preferably blocked polyglycols, water, and, if desired, optional ingredients conventionally used in antiperspirant compositions. The compositions of the invention are suitable for use in a number of different cosmetically manufactured forms, for application on the body and the surface of the skin. The compositions have an excellent efficacy to combat body odor and perspiration and are cosmetically aesthetic. The antiperspirant compositions of the invention are easily applied on the surface of the skin, they dry quickly, and they are not perceived to feel sticky, adherent or sandy, and leave no visible residue after the application. It is an object of the present invention to provide antiperspirant compositions based on water, stable, containing polyglycols for cosmetic use, which very effectively provide non-sticky, water-soluble antiperspirant active materials to the skin, for use in combating perspiration and body odor, for example, in the axillary regions of the human body, applying the antiperspirant compositions to the human body, for example, to the skin in the axillary regions of the body. It is another object of the invention to provide cosmetic compositions of the antiperspirants described above, which do not exhibit stickiness, which feel uniform and dry after application, do not feel greasy or oily, are applied in a clear manner to the skin and they remain clear and clean, that is, they leave no chalky or mealy residue after application, regardless of the ways in which the antiperspirant compositions are delivered (for example, in the aerosol or spinning bead forms, and the like). It is still another object to provide a water-based antiperspirant composition for use in methods to treat or prevent human foul odor associated with perspiration and sweat, especially the bad smell of the armpits. The methods comprise applying to the skin of a human being an effective and safe amount of the antiperspirant compositions of the invention. Still another object of the invention is to provide a water-based antiperspirant solution technology utilizing polyglycols, which minimizes or eliminates stickiness, which dries quickly and which is clear. According to the invention, the technology of the antiperspirant solution is suitable for a wide variety of different delivery forms, has acceptable and advantageous organoleptic qualities, and significantly lower costs than commonly available antiperspirant products, for example, rotating bead products, clear. The technology of the solution of the invention is also economical and easy to manufacture. The additional objects and advantages produced by the invention will be apparent from the detailed description given hereinafter.

Detailed description of the invention The present invention provides water-soluble antiperspirant compositions, completely soluble, to reduce or inhibit sweating and perspiration. In general, . the compositions provide simple and elegant formulations which comprise one or more salts in combination with polyglycols, preferably blocked polyglycols, and water. All of the components of the antiperspirant compositions of the invention are soluble and are in solution in the water-based compositions. The compositions of the invention deposit an effective and adequate amount of the antiperspirant material when the compositions are applied to and rubbed on the skin, for example, in the axillary regions of the body (ie, the compositions have good properties of utility or final result). . Another advantage of the antiperspirant compositions of the invention is that they are simple to produce and avoid the use of multiple phase systems and emulsions. Blocked polyglycols as used herein encompass molecules that are comprised of alternative sections of a chemical composition (eg, PPG) separated by sections of a different chemical nature (e.g., POE). The polyglycols components of the compositions have recently been discovered as novel classes of emollient solvents which have the unique ability, when mixed with aqueous solutions of the popular antiperspirant salts, to form clear solutions which are physically and chemically stable, do not reduce the effectiveness of the antiperspirant salts in the compositions, and do not feel moist during application to the skin. Furthermore, the glycols formulated in the antiperspirant compositions of the invention serve to reduce or eliminate the moisture and tackiness of antiperspirants and do not produce visible residues in the axilla when they are sprayed and dried during application. In addition, these novel compositions do not cause itching or burns during application, and do not increase the irritation of antiperspirant salts in the compositions, in contrast to ethanol. According to the invention, novel antiperspirant compositions comprising polyglycols or need to contain significant amounts of alcohol components. The presence of polyglycols in the antiperspirant compositions of the invention leads to minimization, reduction, or elimination of tackiness. Accordingly, polyglycols, for example, PPG-2-Buteth-3, serve as tackifying agents in the final compositions described herein. In addition, such polyglycols can also function as emollients for the improvement of the organoleptic qualities of the compositions of the invention. invention. It is believed that stickiness can be attributed to an abundance of hydroxyl groups, mainly in the active antiperspirant and aqueous components, but also in the excipient ingredients of the antiperspirant compositions. An excess of hydroxyl groups, in turn, causes a subsequent binding of hydrogen on the skin. Non-limiting examples of the typical excipient ingredients in such formulations which are believed to be associated with the hydrogen bonding of the skin, mentioned above, are glyceryl monostearate stabilized with acid, sodium sulfate and lauryl, sodium sulfate and cetyl, triethanolamine sulfate and lauryl, alkyl aryl sulphates, hexitol ethers of the common fatty acids and their polyoxyethylene derivatives, and polyolioxyethylene esters. Accordingly, the presence of the blocked polyglycols in the novel antiperspirant formulations or compositions of the invention was found to minimize the binding of hydrogen and consequently minimize the perception and the degree of stickiness on the skin. Actually, the results of the sensory studies (Example 1) showed very little stickiness after the application of an exemplary formulation of the invention, comprising one or more blocked polyglycols, against a high degree and stickiness perception using a commercially available antiperspirant formulation (eg, Ban Roll-on) based on an emulsion. Generally speaking, polyglycols for use in the invention are included as elements of the class of polyethylene or polyethylene oxide derivatives, for example, linear polymers of ethylene or propylene oxides having the general formula: CH, I RO- [CH: CHO]. [CH, CHJO]. - H where m can be 0; however, m is generally greater than n; for example, n from 1 to approximately 34, preferably 2 to 20; and m has an average value from about 2 to 45, preferably 3 to 30; and R is an alkyl, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, hexyl, and the like, glyceryl, or H whenever n > 2, preferably n > 6. Water-soluble, liquid-blocked polyglycols are currently preferred in the compositions of the invention.

And OH, CH, wherein, x varies from an average value of about 2 to 33, and varies from an average value of about 3 to 45, and which are compatible with the active antiperspirant salts (eg, aluminum and zirconium salts), they are employed in the compositions of the invention.

In addition, the aluminum and zirconium salts for use in the antiperspirant compositions of the invention can be found by the practitioner and are described in the Cosmetic Ingredients Book of the CTFA, Monographs (1992), for example, on pages 15- 20. Non-limiting examples of the aluminum and zirconium salts that are currently preferred in the compositions of the invention are available from the chemical company Reheis Inc., particularly, the aluminum-zirconium complexes commercially available under the trademark designation REACH. ®. The CTFA nomenclature corresponds to the particular REACH® products as follows: the zirconium-aluminum complexes REACH® AZP 701, 902, and 908 are aluminum-zirconium tetrachlorohydrex-gly with respect to the CTFA nomenclature; the REACH® AZZ 902 zirconium-aluminum complex is aluminum-zirconium trichlorohydrex-gly with respect to the CTFA nomenclature; and the zirconium-aluminum complexes REACH®AZ0 902 and 908 are aluminum-zirconium octachlorohydrex-gly with respect to the CTFA nomenclature. The particular characteristics of the REACH series of active antiperspirants are described in Tables 2 and 3, as presented in the REACH® product brochure of Reheis®: Table 2 REACH ® Aluminum Hydrochlorides Table 3 Complexes of Zirconium-Aluminum REACH Another particular but non-limiting example of an aqueous aluminum and zirconium salt which is very suitable for use in the compositions of the invention, is aluminum-zirconium 35% aqueous tetrachlorohydrex-Gly, commercially available as Westchlor® ZR 35B from Westwood Chemical Corporation, Middletown, NY. The Westchlor ZR 35B is a conventional tetrasal with an atomic ratio of Al / Zr of 3.5: 1 and a ratio of metal / chloride 1.4: 1, and is also cyclo-ocid by those skilled in the art as AZG or ZAG. The OTC Panel on Antiperspirants of the Food and Drug Administration has adopted certain nomenclature and specifications for various aluminum and zirconium polychlorohydrates that are useful in the present invention. These are described in Table 4 given below: Table 4 Nomenclature Interval of Interval of Adopted by Proportion of Proportion of the Panel Metal-Halide Al / Zr Trichlorhydrate below 2.1 but above 2.0 pe-of aluminum and not including 1.5: 1 ro without including zirconium 6.0: 1 Tetrachlorohydrate down from 1.5 up to 2.0 aluminum and not including 0.9: 1 but not including zirconium 6.0: 1 Pentachlorohydrate down from 2.1 up to 6.0 of aluminum and but not including up to and include and zirconium 1.5: 1 do 10.0: 1 Table 4 (Cont.) Octachlorohydrate down from 1.5 up to 6.0 of aluminum and e including 0.9: 1 up to and include zirconium 10.0: 1 It will be appreciated by those skilled in the art that glycine can be bound in the aluminum-zirconium complexes of the antiperspirant active metal salt. In the compositions of the invention, aluminum-zirconium complexes containing glycine are currently preferred. Another non-limiting example of the aluminum metal salt suitable particularly for use in the compositions of the invention is aluminum chlorohydrate, which may be represented by the formula: [A12 (0H) JC1", where m + n = 6, and which covers a range of aluminum to chloride ratios from 2.1 down to but not including 1.9 to 1. Aluminum commercially available hydrochlorides are also preferred under the REACH® trademark designation, as described in Table 2. It will be appreciated by those skilled in the art that products similar to the antiperspirant salts mentioned above are also manufactured by Dow Corning Company. Preferably, in the compositions comprising the antiperspirant salt of aluminum chlorohydrate, an aqueous solution of the antiperspirant (eg, a solution at a concentration of about 50% to 60% in water) can be used. The 50% ACH solution in water can be purchased directly as such from the supplier. The active antiperspirant ingredients are • solubilized in the compositions of the invention in an effective antiperspirant amount to reduce or eliminate perspiration, moisture and bad odor of the body, ie, in an amount sufficient to have an effect of reducing the bad odor of the body by reducing the moisture and the flow of perspiration where it is applied. By reducing the bad odor of the body it is generally understood that there is a minor bad body odor or perspiration moisture after application of the composition to a person's skin, compared to no application on the skin. Such a reduction can be due to a masking of the bad smell, the reduction of the levels of the bacteria which produce the materials that smell bad, for example, of perspiration or sweat, the reduction of perspiration, and the like. In general it is appreciated that the antiperspirant materials act mainly to reduce the bad odor of the body by reducing the production of perspiration or sweat. In general, the active antiperspirant (e.g., the metal antiperspirant salt) is present in the compositions in amounts that are the same as those normally used in the antiperspirant compositions. Typically, the amount is on an active basis and can be from about 2% to about 60% by weight of the composition, preferably about 5% to about 35%, and more preferably up to about 26%. On an anhydrous basis, the amount of the antiperspirant is commonly in the form of about 5% to about 26%. More particularly, the maximum use level for the ACH is typically up to about 26% by weight, while the maximum use level for the AZG is typically up to about 20% by weight, on an anhydrous basis.

In addition, the pH of the compositions of the invention is from about 2.5 to 6.5, preferably, from about 3.0 to 5.5, more preferably in approximate form 3.5 to 4.5. A low pH can be attributed to the active metal salts, antiperspirants, used in the compositions, which are acidic in nature. In general, the components and additives formulated in the compositions of the invention are stable in an acid medium and compatible with acids to provide an optimum useful life and stability. Several of the optional ingredients listed above that can be used in the compositions of the invention are more particularly considered here below: Solvents, Cosolvents, and Solubilizers: If desired, relatively small amounts of solvents and cosolvents, other than water, may be formulated in the compositions of the invention, to aid in the solubilization of the component ingredients of the compositions and to provide optimum clarity of the product. The solvents and co-solvents commonly used are selected from aliphatic dihydroxy alcohols, containing from 3 to 5 carbon atoms, and include, for example, dipropylene glycol, 1,3-propylene glycol; 1,2- propylene glycol, 1,3-butylene glycol; 1,4-butylene glycol; and 1,5-dihydroxypentane. By far the most preferred cosolvent in the compositions of the invention is dipropylene glycol. However, aliphatic dihydroxy ethers, containing from 6 to 10 carbon atoms, such as dibutylene glycol, can also be used. Co-solvents are typically employed at concentrations from about 0% to about 40%, preferably in about 10% to 25%, more preferably in about 5% to 15% form. An additional exemplary class of compounds having a solubilizing function in the antiperspirant compositions of the present invention is that of the alkoxylated alcohols, such as ceteareth-15, ceteareth-16, ceteareth-17, ceteareth-18, ceteareth-20, ceteareth- 23, ceteareth-25, ceteareth-27, ceteareth-28, and ceteareth-30, with ceteareth 20 which is especially suitable for the solubilizing function in the compositions of the invention. As is known to those skilled in the art, ceteareths are further described in the Cosmetic Book of the CTFA, 1992. Table 5 lists the CTFA designations, the technical names, and the registered names of the exemplary cosolvents and solubilizers, suitable for use in the invention: Table 5 Lightening Agents and Agents that Remove the Stickiness: The compositions of the invention may contain small amounts of one, or several, emollients, surfactants and other water soluble or insoluble components which may function additionally to increase clarity or as anti-scaling agents to prevent stickiness of the compositions after they have dried on the surface of the skin. The emollients improve the feel of the compositions and the ease with which they can be applied. Emollients include lubricants and other materials used to improve the organoleptic characteristics of an antiperspirant product, as is well known in the art. Actually, in the compositions of the invention the blocked polyglycols serve as effective emollient solvents, by which they avoid other emollient additives, unless desired or necessary, as optional additives in the compositions. In addition, the compositions may optionally contain semipolar products which are soluble or compatible with propylene glycol or dipropylene glycol, which are known to those skilled in the art and which may be used in the practice of the invention. The emollients and liquid, clear, semipolar surfactants can be used to achieve improved clarity under all temperature conditions, if desired. An exemplary class of compounds that 'satisfy the above description are described in U.S. Pat. No. 4,759,924. Certain of these compounds are commercially available under the tradename PPG-5-Ceteth 20 (available as Pocetyl AWS), PPG-3-Myreth-3, PEG-20-Laurate and Poloxamer 335. The following Table 6 lists other semipolar materials. which can be used.

Lightening agents and tackifiers can typically be employed at a concentration level of from about 0.5% to 12%, preferably, about 1% to 10%, more preferably about 1.5% to 8%.

Perfumes and fragrances: The perfumes and fragrances normally employed in cosmetic compositions such as the antiperspirant compositions of this invention may be employed herein if desired. If used, perfumes or fragrances are stable in acidic medium and are typically present in the compositions at a concentration from 0.01% to about 2%, preferably from about 0.05% to 2%.

Antimicrobial compounds: The antimicrobial 'compounds' (for example, the antibacterial compounds) which can be optionally formulated in the compositions of the invention, if desired, will be the same as those which are normally employed in compositions of this nature. Antibacterial compounds include, for example, Triclosan, benzalkonium chloride, benzethonium chloride, and zinc phenosulfate. Typically, the compositions may contain from about 0.01% to about 2% of the antibacterial agent, preferably in about 0.05% to 1.5% form. The compositions may additionally contain coloring agents, botanicals, or other ingredients used in such compositions, provided that such additives are stable in an acidic medium, and are soluble in and compatible with (or can be formulated as such) the other components. in the compositions. An important factor in the stability, clarity, and final organoleptic characteristics of the antiperspirant products of the invention is the compatibility and solubility of various ingredients components of the novel compositions, as described. According to the invention, the components of the final compositions are completely in solution, whereby the technology of the novel and versatile aqueous solution of the invention is created. It will be appreciated by those of skill in the art that the water-based antiperspirant compositions of the invention are effective and useful as common water-based solution formulations, which, in turn, can be formulated in a variety of cosmetic delivery and / or dosage forms for the application and administration of the antiperspirant active materials. Accordingly, according to the invention, water-based antiperspirants can be manufactured / produced in the following forms, which are not proposed to be limiting: creams; gels; solids (for example, a barrier package, a clear bar); sprinklers (for example, sprinklers equipped with a pump); aerosols (for example, a true or legitimate clear spray); rotating ball devices (for example, for faster-spinning spinning ball devices); rotating ball devices with opacifying substances; foams and similar. Although it is not a requirement for its use, the preferred modes of application of the compositions antiperspirants of the invention are as rotating bead devices, sprinklers, or aerosols. The final antiperspirant products comprising the compositions of the invention are preferably clear during application and drying, ie, transparent with respect to the transmission of light, such that minimal white debris or film is visible on the skin on the application site. If the antiperspirant solutions of the invention had to be formulated in a solid or gelled form, they would preferably allow a sufficient amount of light to pass transversely to make it possible for an observer to see without difficulty an image, for example, the letters, which are placed directly below and in contact with the solid or gel form. In general, the process by which water-based antiperspirant compositions are formulated is as follows: 1. The antiperspirant metal salt solution is mixed with water; 2. The other liquid components are added while mixing at room temperature; and 3. The solid solubilizer is melted with the perfume at 50 ° C and is added to the mixture while stirring. The process of preparing the compositions is efficient, easy, and is very suitable for those present aqueous formulations of the invention. More particularly and with respect to the formulation of the ingredients of the components as exemplified herein, the process essentially involves heating the solubilizer, for example, ceteareth-20, as in Examples 9 and 10, at about 50 ° C until it melts. After this, the other components of the composition are mixed at room temperature in the following order; first, the antiperspirant metal salt, for example, ACH; then the deionized water; then the blocked polyglycol anti-splint agent and the emollient, for example, PPG-2-Buteth-3; then the solvent, for example, dipropylene glycol; and then, the blocked polyglycol emollient, for example, PPG-9 (Witconol PPG-400). While these ingredients are being mixed, the molten solubilizing agent (ceteareth) is added and mixing is continued at room temperature until the ceteareth is completely dissolved (ie, for about 30 minutes). It will be appreciated by those skilled in the art that the blocked polyglycol of PPG-9 can be added prior to the addition of the blocked polyglycol of PPG-2-Buteth-3, without adverse effects and with the same resulting composition. The process of formulating the 'compositions is virtually the same for the whole of the antiperspirant compositions according to the invention. The antiperspirant compositions of this invention when tested to verify their effectiveness substantially as described in Federal Register, Vol. 47, Number 162, August 20, 1982, are as active as commercially available compositions and are optically clear (i.e. , transparent), quick-drying and non-sticky for the user.

EXAMPLES The examples described herein are given by way of illustration only and are not to be construed as limitations of this invention, many obvious variations of which may be made without departing from the spirit or scope thereof.

Example 1 A typical sensory study to evaluate each of the antiperspirant compositions prepared as described in the Examples given hereinafter is generally carried out as described in this Example.

More particularly, protective antiperspirant evaluations are completed by a total of eight panelists during the course of several test sessions, depending on the number of samples of the composition being tested. In the case of four pairs of compositions, four test sessions are used. For example, for samples A-H, the pairs tested are A / B; CD; E / F; and G / H. All samples are presented in pairs, but not all panelists received the same pair in a given session; some panelists tested the A / B pair, while others tested the C / D, E / F, or G / H pairs. In addition, the order of presentation of the samples within each pair is random to minimize the position deviation (eg, A / B, B / A). The antiperspirant products of the sample are applied according to the following protocol: • Director of the designated panel uses an automatic pipette to distribute 0.4 ml of the product. To each of the four sites along a marked area of . 24 cm (6 inches) x 5.08 cm (2 inches) over the palmar forearm, 0.1 ml of the product is distributed. A sample is distributed to the left arm and the second sample is distributed to the right arm. Each of the panelists then applies the product using the index finger (protected by a thimble for the finger) in four upwards, which distributes the product over the evaluation area. The evaluations are made immediately after the application and at intervals of 5, 10 and 20 minutes after this. All the marks or evaluations were carried out on an intensity scale of 100 points from 0 = "nothing in total" to 100 = "a lot". Higher evaluations indicate the presence of more of the particular characteristic that is evaluated. The organoleptic characteristics and aesthetic character of the product are evaluated as defined by the touch on the residual skin and appearance. Specifically, the characteristics of the sample evaluated included, for example, gloss, stickiness or adhesion, (in the folds), stickiness or adhesion (tactile), oil, grease, wax, visible white debris, total waste (tactile), stiffness, whiteness that can be removed by rubbing, opacity, and slippage. Particularly with respect to the evaluation of tackiness, a sample product is routinely evaluated to verify stickiness when the product is dried on the skin after application, for example, as a deodorant applied with a rotating ball device. The evaluator determines the feeling of stickiness or adhesion of the finger product and the feeling of stickiness on the skin when the product is dried after application, for example within the course of up to one minute, preferably within 5 to 30 seconds after application. In general for the compositions of the invention, the faster the composition dries on the skin after application, the less amount of tackiness is discerned or perceived by the evaluator in the sensory test. * The results of a comparison of a sensory test between a commercial emulsion product, common, for example, the Ban Roll-on, and the antiperspirant composition of the invention presented in Table 7, used as a test sample and applied by The mean of a rotating ball is described in Table 8. In Table 7, the numbers in parentheses after each of the characteristics listed on the left side of the Table indicate the minutes after a sample was applied.

The commercial rotating pellet product was found to be brighter, sticky, moist and oily than the test sample of the invention. The commercial product was determined to leave the skin sense more occluded and sandy and had more visual and tactile residues, which were whiter and more opaque, than the minimum or negligible residues of the test sample. In addition, the commercial rotating ball product produced a significantly greater whiteness that can be removed by rubbing when evaluated at the end of the evaluation period. Accordingly, the antiperspirant compositions of the invention provided more pleasing organoleptic characteristics, more advantageous cosmetic features and more satisfactory personal aesthetic characteristics than the commercially available rotating bead product.

Example 2 The components presented in this Example were mixed as described to prepare an antiperspirant composition of the invention. If the appearance of the composition was clear after the formulation, the composition, as a rotating bead product, was briefly and initially evaluated to verify its organoleptic properties in the laboratory directly after its preparation.

After approximately 10 seconds, two fingers were used to feel the area over which the composition has been applied to verify the degree of tackiness (adhesion), the speed of drying, the appearance of residues, and the feel of the film.

The appearance of the composition was clear, and the initial organoleptic evaluation determined that the final composition produced a negligible tack.
