Underarm Products With Water Lock Component
Field of the Invention
This invention relates- to suspension products that are useful to reduce underarm wetness. Optionally -they can include antiperspirant and/or deodorant agents, but are particularly advantageous in providing deodorants that have reduced wetness without the use of ah antiperspirant active. Reference is made to a case filed on the same day as this case and referenced as Attorney Docket Number IR 6642-00.
Background of the Invention
A variety of technologies have attempted to use superabsorbent polymers of various types in a wide variety of applications. These technologies include the, * construction of diaper products for children and adults, and the use of superabsorbent polymers to clean up liquid spills. The problems associated with the use of such polymers in personal care applications include a wet and sticky feel and skin irritation, Additionally, it has been difficult to find a way of applying such products in the underarm area in a way that results in an aesthetically acceptable product form. It has now been found that selected water lock superabsorbent polymers in certain formulations both with and without antiperspirant or deodorant agents may be used to create superior anti-wetness products.
It is also desirable to have the ability to reduce wetness using a deodorant product. While some deodorants contain lesser amounts of antiperspirant actives, there is a segment of the population that prefers to use deodorants that do not contain antiperspirant actives. It would be advantageous to provide a product that reduces wetness without the use of antiperspirant actives.
Brief Summary of the Invention The invention comprises an underarm product suitable for use to reduce wetness under the arm. It may be viewed as providing some deodorancy effect. Optionally, a portion of an antiperspirant active may be included to provide an antiperspirant deodorant. This underarm product is a suspension product which may be a stick or soft solid and which comprises a water lock superabsorbent polymer selected from the group consisting of starch graft homopofymers and copolymers of poly(2-propenamide-co-2-propenioic acid) sodium salt. While these homopolymers and copolymers may be used in a variety of particle sizes, it is generally believed that
and copolymers may be used in a variety of particle sizes, it is generally believed that the smaller sizes are preferred (for example, having 95% of the particles able to go through a 200 mesh screen (comparable to a size of less than 75 microns)). The formulations of the invention may be made as antiperspirants and/or deodorants. In the case of antiperspirants, the products give an extra measure of protection against wetness. In the case of deodorants, the products may be made with low levels of antiperspirant active or with other agents which provide a deodorizing effect but which are not antiperspirant salts.
Detailed Description of the Invention Products formulated according to the invention comprise suspension products which are sticks or soft solids comprising:
(a) 0.01-20 weight % (particularly 0.1-10 % and more particularly 0.5-5%) of a water lock superabsorbent polymer selected from the group consisting of starch graft homopolymers and copolymers of poly(2-ρropenamide-co-2-propenioic acid) sodium salt;
(b) 10-88 weight % of a volatile silicone having a flash point of 100 degrees C or less (particularly a D4-D6 cyclomethicone; and especially a D5 or D6 cyclomethicone or a combination of D5 andDθ cyclomethicones);
(c) a gelling agent selected from the group consisting of 5-30 weight % stearyl alcohol; 0.1-10 weight % (on an actives basis) silicone elastomer; 0.1-20 weight % waxes (for example, Japan wax, hydrogenated castor oil); 1-3 weight % siliconized polyamides (especially of the type described below in Formula EIA); 1-20 weight % low molecular weight polyethylene having a molecular weight in the range of 400-1000 (for 'example 400 such as Performalene-400 from New Phase Technology, Piscataway, New Jersey) and combinations of the foregoing;
(d) 0-5 weight % of a surfactant with a hydrophilic/lipophilic balance ("HLB value") in the range of 3-13 (for example, from 0.05-50 weight % (particularly 1-30%) of a silicone copolyol which is 10% in cyclomethicone, or its equivalent may be used for a soft solid); (e) 0-10 weight % (particularly 5-10 %) of an antiperspirant active or an effective amount of a deodorizing agent which is not an antiperspirant active;
(f) 0-20 weight % (particularly 5-10%) of a nonvolatile silicone having a flash point greater than 100 degrees C; and
(g) 0-20 weight % (particularly 2-12 %) of an emollient (for example, a member selected from the group consisting of C12-15 all yl benzoate, PEG-8 distearate, PPG-3- myristyl ether, and polyisobutene 250).
While no water is recited as being added, up to 2 weight % water may be present because of the types of raw materials used.
With regard to the amount of volatile silicone used in the invention, 10-88 weight % is used for stick products and soft solids.
Optionally, one or more other ingredients can be used such as fragrance, coloring agents, antibacterial agents, masking agents, or fillers (for example, talc). The antiperspirant actives that can be utilized according to the present invention include conventional aluminum and aluminum/zirconium salts, as well as aluminum zirconium salts complexed with a neutral amino acid such as glycine ("gly"), as known in the art. See each of European Patent Application Number 512,770'A1 and PCT case WO 92/19221, the contents of each of which are incorporated herein by reference in their entirety, for disclosure of antiperspirant active materials. The antiperspirant active materials disclosed therein, including the acidic antiperspirant materials, can be incorporated in the compositions of the present invention. Suitable . materials include (but are not limited to) aluminum chlorohydroxide, aluminum chloride, aluminum sesquichlorohydroxide, zirconyl hydroxychloride, and aluminum chlorohydrol-propylene glycol complex. These include, by way of example (and not of a limiting nature), aluminum chlorohydrate, aluminum chloride, aluminum sesquichlorohydrate, zirconyl hydroxychloride, aluminum-zirconium glycine complex (for example, aluminum zirconium trichlorohydrex gly, aluminum zirconium pentachlorohydrex gly, aluminum zirconium tetrachlorohydrex gly and aluminum zirconium octochlorohydrex gly), and mixtures of any of the foregoing. The aluminum- containing materials can be commonly referred to as antiperspirant active aluminum salts. Generally, the foregoing metal antiperspirant active materials are antiperspirant active metal salts. In the embodiments which are antiperspirant compositions according to the present invention, such compositions need not include aluminum- containing metal salts, and can include other antiperspirant active materials, including other antiperspirant active metal salts. Generally, Category I active antiperspirant ingredients listed in the Food and Drug Administration's Monograph on antiperspirant
drugs for over-the-counter human use can be used. In addition, any new drug, not listed in the Monograph, such as tin or titanium analogues of the aluminum slats listed above, aluminum nitratohydrate and its combination with zirconyl hydroxychlorides and nitrates, or aluminum-stannous chlorohydrates, can be incorporated as an antiperspirant active ingredient in antiperspirant compositions according to the present invention. Preferred antiperspirant actives that can be incorporated in the compositions of the present invention include the enhanced efficacy aluminum salts and the enhanced efficacy zirconium/aluminum salt-glycine materials, having enhanced efficacy due to improved molecular distribution, known in the art and discussed, for example, in PCT No. WO92/19221 , the contents of which are incorporated by reference in their entirety herein.
Antiperspirant actives can be incorporated into compositions according to the present invention in amounts in the range of 0 - 10% (on an anhydrous solids basis), preferably 5 - 10%, by weight, of the total weight of the composition. The amount used will depend on the formulation of the composition. For example, at amounts in the lower end of the broader range (for example, 0.1 - 5%), the antiperspirant active material will not substantially reduce the flow of perspiration, but will reduce malodor, for example, by acting as a deodorant material, for example, by acting as an antimicrobial or complexing with the malodorous components of human perspiration. Deodorant active materials can include lesser amounts of antiperspirant actives, such as in the range of 0.1-5%, as well as fragrances, and effective amounts of antimicrobial agents, for example, bacteriostatic quaternary ammonium compounds (such as cetyl trimethyl-ammonium bromide, and cetyl pyridinium chloride), 2, 4, 4'-trichloro-2'- hydroxydiphenylether (Triclosan), N-(4-chlorophenyl)-N' -(3 ,4-dichlorophenyl)urea (Triclocarban), silver halides, octoxyglycerin (SENSIVA™ SC 50) and various zinc salts (for example, zinc ricinoleate) may also be included in formulations of the present invention. The bacteriostat can, illustratively, be included in the composition in an amount of 0.01-5.0% by weight, of the total weight of the composition. Triclosan or Triclocarban can, illustratively, be included in an amount of from 0.05% to about 5.0% by weight, of the total weight of the composition.

Volatile silicones and silicone surfactants are also used in the invention. By volatile silicone material is meant a material that has a flash point of 100 degrees C or less at atmospheric pressure. Such volatile silicones include conventional cyclic and linear volatile , silicones such as cyclomethicone (especially cyclopentasiloxane, also called "D5"), "hexamethyldisiloxane", and low viscosity dimethicone (for example, Dow Co ing® 200 fluid having a viscosity of 0.5-5 centistokes). Illustratively, and not by way of limitation, the volatile silicones are one or
more members selected from the group consisting of cyclic polydimethylsiloxanes such as those represented by Formula IJJ.-S:
CH3
Formula m-S where n is an integer with a value of 3-7, particularly 5-6. For example, DC-245 fluid (or the DC-345 version) from Dow Coming Corporation (Midland, Michigan) is a type of cyclomethicone which can be used. These include a tetramer (or octylmethylcyclotetrasiloxane) and a pentamer (or decamethylcyclopentasiloxane). The volatile linear silicones can also be included in this group of volatile silicones and are one or more members selected from the group consisting of linear polydimethylsiloxanes such as those represented by Formula IV-S:
CH3
I CH3 - [-Si-O]t - CH3
I
CH3
Formula JN-S
and t is selected to obtain a viscosity of 0.5-5 centisto es.
Examples of such volatile silicones include one or more members selected from the group consisting of D4, D5, andD6 cyclomethicones; and linear dimethicones having a viscosity in the range of 0.5-10 centistokes. Preferably the oil phase is a mixture of one or more of D4, D5 and D6 cyclomethicones. Suitable silicone surfactants include silicone polyglucosides (for example, octyl dimethicone ethoxy glucoside) and silicone copolyols " having an FfLB value (hydrophilic lipophilic balance) in the range of 3-13. A silicone copolyol (especially dimethicone copolyol) may be used in an amount of 0.05-5.0 weight % (actives basis), particularly 0.1-3.0% and, more particularly, 0.1-2.0 %. In general, silicone copolyols useful in the present invention include copolyols of the following Formulae I-S and IJ-S. Formula I materials may be represented by:
(R10)3-SiO-[(R11)2-SiO]x - [Si(R12)(Rb-O-(C2H4O)p-(C3H6O)s-Rc)O]y-Si-(R13)3
Formula I-S wherein each of R10 , Ru , R12 and R13 may be the same or different and each is selected from the group consisting of C1-C6 alkyl; Rb is the radical -CmH2m-; Rc is a terminating radical which can be hydrogen, an alkyl group of one to six carbon atoms, an ester group such as acyl, or an aryl group such as phenyl; m has a value of two to eight; p and s have values such that the oxyalkylene segment -(C2H O)p-(C3H6θ)s- has a molecular weight in the range of 200 to 5,000; the segment preferably having fifty to one hundred mole percent of oxyethylene units -(C2H4θ)p- and one to fifty mole percent of oxypropylene units -(C3H6O)s-; x has a value of 8 to 400; and y has a value of 2 to 40. Preferably each of R10 , R11 , R12 and R13 is a methyl group; Rc is H; m is preferably three or four whereby the group Rb is most preferably the radical '-(CH2)3-; and the values of p and s are such as to provide a molecular weight of the oxyalkylene segment -(C2F4θ)p-(C3H6θ)s- of between about 1,000 to 3,000. Most preferably p and s should each have a value of about 18 to 28.
A second siloxane polyether (copolyol) has the Formula II-S:
(R10)3-SiO-[(Rπ)2-SiO]x - [Si(R12)(R -O-(C2H4O)p-Rc)O]y -Si-(R13)3 Formula IJ-S wherein p has a value of 6 to 16; x has a value of 6 tolOO; and y has a value of 1 to 20 and the other moieties have the same definition as defined in Formula I-S.
It should be understood that in both Formulas I and π shown above, that the siloxane-oxyalkylene copolymers of the present invention may, in alternate embodiments, take the form of endblocked polyethers in which the linking group Rb, the oxyalkylene segments, and the terminating radical Rc occupy positions bonded to the ends of the siloxane chain, rather than being bonded to a silicon atom in the siloxane chain. Thus, one or more of the R10 , R11 , R12 and R13 substituents which are attached to the two terminal silicon atoms at the end of the siloxane chain can be substituted with the segment -R -O-(C2H4O)p-(C3H6O)s-Rc or with the segment -Rb-O- (C2H O)p-Rc. In some instances, it may be desirable to provide the segment -Rb-O-
(C2H4O)p-(C3H6θ)s-Rc or the segment -Rb-O-(C2FJ θ)p-Rc at locations which are in the siloxane chain as well as at locations at one or both of the siloxane chain ends.
Particular examples of suitable dimethicone copolyols are available either commercially or experimentally from a variety of suppliers including Dow Coming Corporation, Midland, MI; General Electric Company, Waterford, NY; Witco Corp., Greenwich, CT; and Goldschmidt Chemical Corporation, Hopewell, NA. Examples of specific products include DOW CORNING® 5225C from Dow Coming which is a 10% dimethicone copolyol in cyclomethicone; DOW CORNING® 2-5185C which is a 45-49% dimethicone copolyol in cyclomethicone; SILWET L-7622 from Witco; ABIL EM97 from Goldschmidt which is a 85% dimethicone copolyol in D5 cyclomethicone; and various dimethicone copolyols available either commercially or in the literature.
It should also be noted that various concentrations of the dimethicone copolyols in cyclomethicone can be used. While a concentration of 10% in cyclomethicone is frequently seen commercially, other concentrations can be made by stripping off the cyclomethicone or adding additional cyclomethicone. The higher concentration materials such as DOW CORNING® 2-5185 material is of particular interest.
In one particular embodiment 0.5-50 weight % (particularly 10-30 %) of a 10% silicone copolyol such as dimethicone copolyol in cyclomethicone mixture may be used, wherein the amount of mixture added is selected so that the level of silicone copolyol in the cosmetic composition is in the range of 0.05-5.0% (particularly 0.1-
3.0%).
Non-volatile silicones may also be used in the formulations of this invention. Such nonvolatile silicones have a flash point greater than 100 degrees C and a viscosity in the range of 6-1000 centistokes. Suitable non volatile silicones include linear organo-substituted polysiloxanes which are polymers of silicon/oxygen with a general structure:
(1) (R10)3SiO(Si (Ru)2O)xSi(R12)3 where R10, Rπ and R12 can be the same or different and are each independently selected from the group consisting of phenyl and C1-C60 alkyl; or (2) HO(R14)2SiO(Si (R)5)2O)xSi(R16)2OH, where R14, R15 and R16 can be the same or different and are each independently selected from the group consisting of phenyl and C1-C60 alkyl.

Emollients are a known class of materials in this art, imparting a soothing effect to the skin. These are ingredients that help to maintain the soft, smooth, and pliable appearance of the skin. Emollients are also known to reduce whitening on the skin and/or improve aesthetics. Examples of chemical classes from which suitable emollients can be found include:
(a) fats and oils which are the glyceryl esters of fatty acids, or triglycerides, normally found in animal and plant tissues, including those which have been hydrogenated to reduce or eliminate unsaturation. Also included are synthetically prepared esters of glycerin and fatty acids. Isolated and purified fatty acids can be esterified with glycerin to yield mono-, di-, and triglycerides. These are relatively pure fats which differ only slightly from the fats and oils found in nature. The general structure may be represented by Formula HI:
CHz-COOR1
CH-COOR2 CH2-COOR3
Formula HI wherein each of R1, R2, and R3 may be the same or different and have a carbon chain length (saturated or unsaturated) of 7 to 25.
