Description

NON-AEROSOL MOUSSE COMPOSITIONS

TECHNICAL FIELD

The present invention relates to a non-aerosol mousse composition which can provide good foam density, good setting power, good dispensability, low stickiness, and good spreadability in the absence of pressurized propellants.

BACKGROUND

Leave-on foaming cosmetic compositions for hair are usually referred to as "mousses", which term will be used in the present invention. Mousses were born in Europe in the early 1980s. Mousses are fundamentally an aerosol foam, however, non-aerosol foams are also known. Mousses are formulated for the purpose of styling, setting, and arranging, or for other purposes such as shampooing, conditioning, treating, dyeing, and combinations thereof. Mousses can be applied to the hair by spreading it through the hair with the user's hand or with a comb designed for the purpose. The general appeal of mousses can be largely attributed to the ease of application and capability to provide control as to the amount and distribution of product.

In the art, mousse compositions are generally formulated with pressurized propellants and packed in pressure resistant bomb-type packaging which is equipped with, for example, a compressible dispenser, a nozzle, or a valve. Selection of the type and quantity of propellants are known to affect the characteristic of the foam.

Favorable propellants for providing a good foam, such as LPG and dimethylether, are generally highly flammable and less safe for the consumer. Further, the pressure resistant packages used for containing pressurized propellants are expensive, and require special procedures in the manufacturing process. This can result in a costly product. Further, pressure resistant packages cannot be re-filled by the consumer, and are difficult to re-use or recycle in the industry. This is not preferable from an environmental standpoint. Attempts to provide mousse compositions without pressurized propellant have been suggested in the art. However, lack of pressurized propellant generally provided products with poor foam appearance and stability, which resulted in a product having less control of amount and distribution to the hair. Based on the foregoing, there is a need for a mousse composition which does not include a pressurized propellant, yet still providing the good foaming characteristics typically obtained by pressurized propellant-containing mousse compositions.

None of the existing art provides all of the advantages and benefits of the present invention.

SUMMARY

The present invention is directed to a non-aerosol mousse composition comprising: (a) from about 0.1 % to about 10% by weight of a primary fixative polymer selected from betainized amphoteric fixative polymers; and (b) an aqueous carrier comprising no more than about 30% of a volatile solvent by weight to the composition; wherein the composition is substantially free of pressurized propellants, and is capable of generating a foam having a foam density of from about 0.025g/mL to about 0.1g/mL. These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.

DETAILED DESCRIPTION While the specification concludes with claims particularly pointing and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description.

All percentages are by weight of the total composition unless otherwise indicated. All ratios are weight ratios unless otherwise indicated. All percentages, ratios, and levels of ingredients referred to herein are based on the actual amount of the ingredient, and do not include solvents, fillers, or other materials with which the ingredient may be combined as commercially available products, unless otherwise indicated. As used herein, "comprising" means that other steps and other ingredients which do not affect the end result can be added. This term encompasses the terms "consisting of and "consisting essentially of.

All cited references are incorporated herein by reference in their entireties. Citation of any reference is not an admission regarding any determination as to its availability as prior art to the claimed invention. FIXATIVE POLYMERS

The primary fixative polymer and optional secondary fixative polymers useful herein are those which provide a styling or setting benefit to the hair. The fixative polymers in this section can be distinguished from the conditioning agent polymers as mentioned below in that fixative polymers have a film-forming characteristic.

Compositions herein comprise a primary fixative polymer and optionally a secondary fixative polymer. Primary fixative polymers are selected from betainized amphoteric fixative polymers. Preferably, a secondary fixative polymer is contained. Secondary fixative polymers are selected from the group consisting of non-betainized amphoteric fixative polymers, anionic fixative polymers, cationic fixative polymers, nonionic fixative polymers, silicone grafted copolymers, and mixtures thereof. Preferred secondary fixative polymers are non-betainized amphoteric fixative polymers, and anionic fixative polymers.

The primary fixative polymer and optional secondary fixative polymers are selected so that, the composition is capable of generating a foam having a foam density of from about 0.025g/mL to about 0.1g/mL, preferably not more than about 0.075g/mL, more preferably not more than about 0.065g/mL, in the absence of any pressurized propellant. It is believed that such foam density provides good foaming characteristics, such as good foam appearance and good foam retention time, which allow the ease of application and control of the amount and distribution of the product to the hair.

The compositions herein further have a low viscosity, i.e., the 3% water solution provides a viscosity of less than about 50cps. This can be perceived as good dispensability and low stickiness of the product to the consumer. The compositions herein still further have good setting power.

By using the primary fixative polymer and optional secondary fixative polymers, a composition which provides high foamability is provided. Thus, compositions herein do not require the aid of pressurized propellants. Rather, propellants are preferably not included, as propellants may provide a foam having such long retention time that it would cause insufficient dosage of the product.

The total of the fixative polymers are preferably included at a level of from about 0.2% to about 15% by weight of the composition. The primary fixative polymer is comprised at a level of from about 0.1% to about 10%, preferably from about 1% to about 5% by weight of the composition. The secondary fixative polymer, when present, is comprised at a level of from about 0.1 % to about 10%, preferably from about 0.5% to about 2% by weight of the composition. When more than one polymer is used for the secondary fixative polymer, each fixative polymer does not exceed about 2% by weight of the composition. Preferably, the level of the primary fixative polymer is higher than that of the secondary fixative polymer. Primary Fixative Polymers Primary fixative polymers are selected from betainized amphoteric fixative polymers.

References disclosing suitable nonvolatile dispersed silicone compounds include U.S. Patent No. 2,826,551 , to Geen; U.S. Patent No. 3,964,500, to Drakoff, issued June 22, 1976; U.S. Patent No. 4,364,837, to Pader; and British Patent No. 849,433, to Woolston, all of which are incorporated herein by reference in their entirety. Also incorporated herein by reference in its entirety is "Silicon Compounds" distributed by Petrarch Systems, Inc., 1984. This reference provides an extensive, though not exclusive, listing of suitable silicone compounds.

Another nonvolatile dispersed silicone that can be especially useful is a silicone gum. The term "silicone gum", as used herein, means a polyorganosiloxane material having a viscosity at 25°C of greater than or equal to 1 ,000,000 centistokes. It is recognized that the silicone gums described herein can also have some overlap with the above-disclosed silicone compounds. This overlap is not intended as a limitation on any of these materials. Silicone gums are described by Petrarch, and others including U.S. Patent No. 4,152,416, to Spitzer et al., issued May 1 , 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. Also describing silicone gums are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. All of these described references are incorporated herein by reference in their entirety. The "silicone gums" will typically have a mass molecular weight in excess of about 200,000, generally between about 200,000 and about 1 ,000,000. Specific examples include polydimethylsiloxane, polydimethylsiloxane methylvinylsiloxane) copolymer, polydimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof.

Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of trifunctional and tetra-functional silanes with mono-functional or di-functional, or both, silanes during manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units, and hence, a sufficient level of crosslinking, such that they dry down to a rigid, or hard, film are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen:silicon atoms is at least about 1.2:1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinylchlorosilanes, and tetrachlorosilane, with the methyl substituted silanes being most commonly utilized. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resins for use herein should be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Without being bound by theory, it is believed that the silicone resins can enhance deposition of other silicone compounds on the hair and can enhance the glossiness of hair with high refractive index volumes.

Other useful silicone resins are silicone resin powders such as the material given the CTFA designation polymethylsilsequioxane, which is commercially available as TospearfM f_rom Toshiba Silicones.

The method of manufacturing these silicone compounds, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp 204-308, John Wiley & Sons, Inc., 1989, which is incorporated herein by reference in its entirety.

Silicone materials and silicone resins in particular, can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as the "MDTQ" nomenclature. Under this system, the silicone is described according to the presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the mono-functional unit (CH3)3SiO).5; D denotes the difunctional unit (CH3)2SiO; T denotes the trifunctional unit (CH3)SiO-] 5; and Q denotes the quadri- or tetra-functional unit Siθ2- Primes of the unit symbols, e.g., M', D', T, and Q' denote substituents other than methyl, and must be specifically defined for each occurrence. Typical alternate substituents include groups such as vinyl, phenyl, amino, hydroxyl, etc. The molar ratios of the various units, either in terms of subscripts to the symbols indicating the total number of each type of unit in the silicone, or an average thereof, or as specifically indicated ratios in combination with molecular weight, complete the description of the silicone material under the MDTQ system. Higher relative molar amounts of T, Q, T and/or Q' to D, D', M and/or or M' in a silicone resin is indicative of higher levels of crosslinking. As discussed before, however, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio.

The silicone resins for use herein which are preferred are MQ, MT, MTQ, MQ and MDTQ resins. Thus, the preferred silicone substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the average molecular weight of the resin is from about 1000 to about 10,000. Non-volatile solvents Non-volatile solvents useful herein include alkyl alcohols having more than

3 carbons, and polyhydric alcohols. The polyhydric alcohols useful herein include 1 ,2-propane diol or propylene glycol, 1 ,3-propane diol, hexylene glycol, glycerin, diethylene glycol, dipropylene glycol, 1 ,2-butylene glycol, and 1 ,4- butylene glycol. ADDITIONAL COMPONENTS

Examples 1 through 6 have many advantages. For example, they are capable of generating a foam having a foam density of between 0.025mL and 0.1g/mL when passed through the pump foamer dispenser. Examples 1 through 6 further provide low viscosity, good setting power, and low stickiness. It is understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to one skilled in the art without departing from its spirit and scope.
