Description

SHAMPOO CONDITIONERS CONTAINING POLYALQUILENGLICOL PE FIELD THE IVENTION This invention relates to shampoo compositions containing selected hair conditioning silicone agents and polyalkylene glycols that provide better dispersion through the hair and a denser, more vibrant sensation of soaping.

BACKGROUND OF THE INVENTION Shampoo compositions comprising various combinations of detergent surfactants and silicone conditioning agents are well known. Many of these compositions have provided excellent cleaning and conditioning conditions from a single composition. An important characteristic of most shampoo compositions, whether of the conditioning type or not) is the formation of the suds. Consumers usually associate a generous suds with a greater cleaning effect and a poor suds with a less cleaning effect. In shampoo compositions containing silicone hair conditioning agents, this high degree of sudsing is especially important to impart to consumers the feeling that the efficacy in hair cleaning is not compromised in favor of conditioning activity. Therefore, it has become a conventional practice to highlight the sudsing action of shampoo compositions containing silicone, increasing the level of ingredients or adding more ingredients, which promotes an abundant generation of suds, examples of which above includes high levels of detergent surfactants such as alkyl sulfate surfactants or the addition of mono- and di-alkanol (C 1 -C 3) amide foam activators of fatty esters (eg C 10 -C 22). Shampoos that contain silicone with abundant soap generation produce, however, a foamy and light suds that consumers associate with a good cleaning performance but with a poor performance or less effective in conditioning. In addition, these silicone-containing shampoos as well as other shampoos typically contain higher concentrations of detergent surfactant to improve suds performance, whose higher concentrations are more expensive and unnecessary to provide acceptable hair-cleaning performance. In view of the foregoing, there remains a need to provide conditioning shampoo compositions containing silicone conditioning agents that provide improved sudsing performance, where improved suds performance conveys an impression, during use, of the performance conditioner and Effective cleaning. Accordingly, it is an object of the present invention to provide a silicone-containing shampoo composition with improved sudsing performance, and furthermore to provide this composition with improved dispersibility throughout the hair, thus also improving the conditioning print that It is imparted to consumers. Still another object of the present invention is to provide a composition with acceptable performance in cleaning and conditioning, but with lower concentrations of detergent surfactant.

SUMMARY OF THE INVENTION The present invention is directed to conditioning shampoo compositions comprising from about 5% to about 50% by weight of a detergent surfactant, from about 0.05% to about 10% by weight of a silicone hair conditioning agent , from about 0.1% to about 10% by weight of a suspending agent, from about 20% to about 94.8% by weight of water, and from about 0.025% to about 1.5% by weight of selected polyalkylene glycols, which have the general formula: H (OCH2CH) n-OH R wherein R is hydrogen, methyl or mixtures thereof, and n is an integer from about 1,500 to 25,000; and water, and optionally one or more additional materials that are known in the use of the shampoo compositions. The shampoo-conditioner compositions of the present invention provide improved dispersibility of the composition throughout the hair, and also provide a feeling of a thicker, thicker generation of suds than the consumer relates to improved performance in hair conditioning. . The present invention is also directed to methods for cleansing and conditioning hair or skin, by the use of shampoo compositions such as those described herein.

Another category of insoluble and non-volatile silicone fluid conditioning agents are high refractive index silicones having a refractive index of at least about 1.46, preferably at least about 1.48, more preferably at least less about 1.52, and still more preferably at least about 1.55. While not necessarily intended to be limited, the refractive index of the polysiloxane fluid will generally be less than about 1.70, typically less than about 1.60. The polysiloxane "fluid" includes both oils and gums. The high refractive index polysiloxane fluid suitable for the purposes of the present invention includes those represented by the above General Formula (I), as well as cyclic polysiloxanes, such as those represented by the following Formula (VI): wherein R is as defined above, n is between about 3 and about 7, preferably between 3 and 5. The high refractive index polysiloxane fluids contain a sufficient amount of R substituents containing aryl to increase the refractive index at the desired level, which is described above. In addition, R and n can be selected so that the material is non-volatile, as defined. The aryl-containing substituents contain five- and six-membered heterocyclic and alicyclic aryl rings, and substituents containing fused five- or six-membered rings.

In general, the polysiloxane fluids herein will have a surface tension of at least about 24 dynes / cm2, typically at least about 25 dynes / cm2. For the purposes of this, the surface tension is measured by a Nouy ring tensiometer according to the Dow Corning CTM 0461 Corporate Test Method, November 23, 1971. Changes in surface tension can be measured according to the method of previous test or according to ASTM D 1331 method.

When fluorinated surfactants are used, the high proportions between polysiloxane and dispersing agent due to the efficacy of these surfactants can be effective. Therefore, proportions significantly greater than 1000.1 are contemplated, which may be used. Examples that disclose references to some of the silicone fluids suitable for shampoo compositions include U.S. Patent No. 2,826,551, U.S. Patent 4,364,837, British Patent 849,433, and Silicon Compounds, Petrarch Systems, Inc. (1984 ), all of which are mentioned here by reference. The silicone resins can be included in the silicone conditioning agent. These resins are highly crosslinked polymeric siloxane systems. Cross-linking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional silanes or both, during the manufacture of the silicone resin. As will be well understood in the art, the degree of crosslinking that is required in order to obtain a silicone resin will vary according to the specific silane units incorporated in the silicone resin. In general, silicone materials that have a sufficient level of trifunctional and tetrafunctional monomeric siloxane units (and therefore a sufficient level of crosslinking) so that they dry to a rigid or hard film are considered as resins of silicone The ratio of oxygen atoms to silicone atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials having at least about 1.1 oxygen per silicon atom in general will be the silicone resins herein. Preferably, the ratio between oxygen: silicon atoms is at least about 1.2: 1.0. The silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl, monovinyl, and methylvinyl-chlorosilanes, and tetrachlorosilane, with the methyl-substituted silanes being the most commonly used. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in a form dissolved in a non-volatile or volatile silicone fluid of low viscosity. The silicone resins that are used herein should be provided and incorporated into the compositions herein in this dissolved form, as will be readily apparent to those of skill in the art. The background material on silicones, including sections that analyze silicone fluids, gums and resins, as well as the manufacture of silicones, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp 204-308, John Wiley &; Sons, Inc., 1989, which is mentioned here by reference. Silicone materials and silicone resins and silicone resins, in particular, can conveniently be identified according to a short nomenclature system well known to those skilled in the art, the "MDTQ" nomenglatura. According to this system, the silicone is described according to the presence of several monomeric siloxane units that form the silicone. In summary, the symbol M denotes the monofunctional unit (CH -, SiO.-; D denotes the difunctional unit (CH3) 2 SiO; T denotes the trifunctional unit (CH3) SiO? .5; and Q denotes the quadri- or tetra-functional units Si02. The prime symbols of these literals, for example M ', D', T1, and Q 'denote substituents other than methyl, and must be specifically defined each time they appear. Typical alternating substituents include groups such as vinyl, phenyls, amines, hydroxyls, etc. The molar ratio of the different units, either in terms of sub-indices to the literals that indicate the total number of each type of units in the silicon (or an average thereof) or as the ratios specifically indicated in combination with the molecular weight , complete the description of the silicone material according to the MDTQ system. The relatively high molar amounts of T, Q, T1 and / or Q 'relative to D, D', M and / or M 'in a silicone resin are indicative of high levels of crosslinking. As discussed above, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio. The silicone resins that are used herein and are preferred are MQ, MT, MTQ, MDT and MDTQ resins. In this way, the preferred silicone substituent is methyl. MQ resins are especially preferred wherein the M: Q ratio is between about 0.5: 1.0 to about 1.5: 1.0 and the average molecular weight of the resin is between 1000 to about 10,000. The weight ratio of the non-volatile silicone fluid, having a refractive index of less than 1.46 with respect to the silicone resin component, when used, is preferably between about 4: 1 to about 400: 1, preferably this ratio is between about 9: 1 to about 200: 1, more preferably between about 19: 1 to about 100: 1, particularly when the silicone fluid component is a polydimethylsiloxane fluid or a mixture of polydimethylsiloxane fluid and polydimethylsiloxane gum , as described before. As long as the silicone resin forms a part of the same phase in the composition as a silicone fluid, ie active conditioning component, the sum of fluid and resin should be included when determining the level of silicone conditioning agent in the composition.

The effective concentrations of the selected polyethylene glycols range from about 0.025% to about 1.5%, preferably from about 0.05% to about 1%, more preferably from about 0.1% to about 0.5% by weight of the shampoo compositions.

When R is hydrogen, these materials are polymers of ethylene oxide which are also known as polyethylene oxides, polyoxyethylenes and polyethylene glycols. When R is methyl, these materials are polymers of propylene oxide, which are also known as propylene oxides, polyoxypropylenes and polypropylene glycols. When R is methyl, it is also understood that several positional isomers of the resulting polymer may exist. Specific examples of suitable polyethylene glycol polymers include PEG-2M, where R is equal to hydrogen and n has an average value of about 2,000 (PEG 2-M is also known as Poliox WSR® N-10, which is obtained from Union Carbide and as PEG-2,000); PEG-5M wherein R is hydrogen and n has an average value of about 5,000 (PEG 5-M is also known as Poliox WSR® N-35 and Poliox WSR® N-80 both available from Union Carbide and as PEG-5, 000 and Polyethylene Glycol 300,000); PEG-7M wherein R is hydrogen and n has an average value of about 7,000 (PEG 7-M is also known as Poliox WSR® N-750 available from Union Carbide) PEG-9M wherein R is hydrogen and n has average value of about 9,000 (PEG 9-M is also known as Poliox WSR® N-3333 available from Union Carbide); and PEG-14 M wherein R is hydrogen and n has an average value of about 14,000 (PEG 14-M also available as Poliox WSR® N-3000 from Union Carbide). Suitable polyalkylene polymers include polypropylene glycols and mixed polyethylene / polypropylene glycols. It has been found that these polyalkylene glycols, when added to the conditioner shampoo compositions described herein, improve the suds formation by providing a denser and richer sudsy feel which is correlated by the consumer with a perception of better conditioning. hair related. Although polyethylene glycols, for example, are known to be used to improve sudsing in cleaning compositions, applicants are not aware of any previous prior art showing the use of these selected polyalkylene glycols in shampoo compositions containing silicone. It has also been found that these selected polyalkylene glycols, when added to a silicone-containing shampoo composition, improve the dispersibility of shampoo compositions in the hair. It improves the dispersion of the shampoo composition during the application, providing the consumer with the perception of better conditioning. This work is especially surprising from these selected polyethylene glycols which are known as thickening agents, and as thickening agents it would be expected to impair the dispersibility of the shampoo compositions in the hair instead of improving it. It has also been found, in the presence of selected polyalkylene glycols, that the concentrations of detergent surfactant can be reduced in shampoo compositions containing silicone. In these compositions with reduced surfactant content, the conditioning and cleaning functions are kept in good condition while there is an improved generation of sudsing.

EXAMPLES The compositions illustrated in Examples I-XX illustrate the specific embodiments of the shampoo compositions of this invention, but are not intended to limit the scope thereof. Other modifications can be made by the experts in this field without departing from the true spirit and scope of the invention. The compositions illustrated in Examples I-XX are prepared in the following manner (all percentages are based on weight unless otherwise specified). First, a silicone premix is prepared by adding 70% dimethicone, 29% laureth-3 ammonium sulfate (base solution, 26% active) and 1% sodium chloride, all by weight silicone premix, to a container of high shear mixing and are mixed for approximately 30 minutes or until the desired particle size of the silicone has been achieved (typically a numerical average particle size of between about 5 microns and 25 microns). A conventional silicone emulsion can be used. For each of the compositions illustrated in Examples I-XX, about one third of all total alkyl sulfate surfactant is added to a jacketed mixing tank and heated to about 74 ° C with little agitation to form a surfactant solution the fatty alcohol and cocamide monoethanolamide, as the case may be, are added to the tank and allowed to disperse.

Afterwards, ethylene glycol distearate is added (EGDS) to the reaction vessel and melts. After the EGDS is well dispersed (usually after about 5 to 20 minutes) a preservative is optionally added and mixed in the surfactant solution. This mixture is passed through a heat exchanger where it is cooled to approximately 35 ° C and collected in a finishing tank. As a result of this cooling step, the ethylene glycol distearate is crystallized from a crystalline lattice of the product. The remaining ammonium laureth sulfate, lauryl sulfate and other ingredients, including the silicone premix, are added to the finishing tank with strong agitation to ensure a homogeneous mixture. A sufficient amount of the silicone premix is added to provide the desired level of dimethicone in the final product. The polyethylene glycol and the optional Polyquaternium 10 are dispersed in water as a 1% to 10% solution before being added to the final mixture.
