Description: Hair Cosmetic Technical Field The present invention relates to hair styling mousse products. In particular it relates to non-aerosol hair styling mousse products which provide optimum foaming, hair setting, hair feel and hair conditioning characteristics while reducing stickiness and being easily spreadable on the hair. Background of the Invention The desire to have hair retain a particular shape or configuration is one that is widely held. It is possible to alter the shape of the hair either permanently or temporarily. Permanent alteration involves the use of chemical agents to react with the hair in order to achieve the desired effect. This process can be carried out at either room or elevated temperature. The temporary set given to hair is, as the term indicates, a temporary arrangement which can be removed by water or by shampooing. The materials used to provide the set have generally been resins or gums. The temporary set compositions have taken the form of gels, lotions and sprays as well as others. The compositions are applied most often to hair dampened with water, combed or by other means spread through the hair and let dry. The set given will vary depending on the materials used. In recent years a form of a temporary set has been achieved by means of an aerosol foam - a mousse. The general appeal of mousses can be largely attributed to the ease of application and controlled amount of product which are possible from mousse formulations. Mousse formulations can easily be /02115 worked through the hair and can provide a set comparable to that given by a gel or a lotion. These products are generally applied to the user's hand and worked through the hair. The conventional hair styling mousse generally utilizes a water soluble polymer, water, possibly a conditioning agent, an emulsifier, aesthetic agents and the propellant. More recently, however, due to an increasing public awareness of the effects of volatile organic compounds, such as aerosol propellants, on the environment, hair styling mousse products have been formulated without a propellant and dispensed from a manually-actuable container so as to be of the non-aerosol type. Unfortunately, however, there are a number of problems associated with non-aerosol products. In particular they provide mousses which are of poor foam quality and stability and which are undesirably sticky. Moreover, many of these formulations are lacking in hair holding, hair feel or hair conditioning characteristics. It would be desirable to provide a non-aerosol, hair styling mousse product which provides a high quality mousse with the desired combination of good initial foam formation, foam breakdown under shear, non-soapiness and easy spreadability, while at the same time not being too sticky. It would also be desirable to provide a non-aerosol hair styling mousse product with improved foaming quality together with good hold, hair feel and conditioning. It has now been found that by including an amphoteric surfactant and a water- soluble cationic surfactant in a non-aerosol mousse composition containing certain polymer resins, a mousse is provided which possesses the desired characteristics of good quality foaming, easy spreadability, non-stickiness, hold, feel and conditioning. Accordingly it is an object of the present invention to provide a superior non- aerosol hair styling mousse product by incorporating therein a selected mixture of amphoteric surfactant, water-soluble cationic surfactant and polymer resins. All percentages and ratios used herein are by weight unless otherwise specified. Summary of the Invention According to one aspect of the present invention there is provided a hair styling mousse product comprising a manually-actuable, non-aerosol dispenser equipped with a reservoir, spray head and liquid/air mixing means, wherein the reservoir contains a hair-styling mousse composition comprising: (i) from about 0.5 % to about 10 % by weight of composition of a nonionic, amphoteric or anionic hair setting polymer resin, and/or (ii) from about 0.5 % to about 10 % by weight of composition of a polycationic hair conditioning polymer resin, (iii) from about 0.1 % to about 3 % by weight of composition of an . amphoteric surfactant, (iv) from about 0.01 % to about 1 % by weight of composition of a water-soluble cationic surfactant, and 4 (v) water or a water/solvent mixture.

Suitable solvents include lower (e.g. C1-C5) alcohols and polyols such as isopropyl alcohol, propylene glycol, ethanol, hexylene glycol, glycerine, propane diols, etc. The mousse compositions of the present invention can also contain a variety of non-essential, optional components such as preservatives, emulsifiers, block polymers, thickeners and viscosity modifiers, fatty alcohols, pH adjusting agents, colouring agents, hair oxidizing agents, hair reducing agents, perfume oils, perfume solubilizing agents, sequestering agents, polymer plasticizing /02115 agents and volatile and non-volatile silicone fluids. Such conventional optional ingredients are well known to a person skilled in the art, e.g. preservatives such as benzyl alcohol, methyl paraben, propyl paraben, imidazolidinyl urea, and DMDM Hydaπtoin; emulsifiers such as aπionics (e.g., sodium alkyl sulphate) and nonionics (amine oxides); thickeners and viscosity modifiers such as diethanolamides of long chain fatty acids; block polymers of ethylene oxide and propylene oxide such as Pluronic (RTM) F88 offered by BASF Wyandotte; fatty alcohols such as cetearyl alcohol; viscosity modifiers such as sodium chloride, sodium sulphate, and ethyl alcohol; pH adjusting agents such as citric acid, succinic acid, sodium hydroxide and triethanolamine; colouring agents such as any of the FD & C or D & C dyes; hair oxidizing (bleaching) agents such as hydrogen peroxide, perborate salts and persulphate salts; hair reducing agents such as the thioglycolates; perfume oils such as Florasynth (RTM) perfumes; perfume oil solubilizers such as polyethylene glycol fatty acid esters; sequestering agents such as ethylenediamine tetraacteic acid; and, among many other agents, polymer plasticizing agents such as glycerin and propylene glycol. These optional materials can be present at a level of from about 0.01 % to about 10 %, preferably from about 0.5 % to about 5 % by weight of composition. The mousse compositions are dispensed using a manually-actuable, non- aerosol dispenser such as a pump-actuated or compressible dispenser. Compressible, non-aerosol dispenser of the so-called "squeeze-foamer" type comprise a reservoir, a dispensing head, liquid/air mixing means and preferably, homogenizing means and non-return valve means. Squeeze foamer packages are well known as exemplified by the disclosures in the following patents: US-A-3,709,437 (Wright, issued January 9th, 1973); US-A-3,937,364 (Wright, issued February 10th, 1976); US-A-4,022,351 (Wright, issued May 10th, 1977); US-A-4, 147,306 (Bennett, issued April 3rd, 1979); US-A-4, 184,615 (Wright, issued January 22nd, 1980); US-A-4,598,862 (Rice, issued July 8th, 1986); US-A-4,615,467 (Grogan et al., issued October 7th, 1986); and FR-A-2,604,622 (Verlhulst, published April 8th, 1988). The above packages do not use any propellant and are therefore safe for the consumer and the environment. The mousse composition is placed in the container reservoir which may for instance, take the form of a plastic squeeze bottle. Squeezing the container reservoir with the hand forces the composition through liquid/air mixing means where the composition is mixed with air and then preferably through a homogenizing means that makes the foam more homogeneous and controls the consistency of the foam. The fpam is then discharged as a uniform, non-pressurized aerated foam through the dispensing head of the dispenser. The minimum force to activate the squeeze foamer is about 1 psig, preferably from about 2 psig to about 15 psig. The minimum force is related to the size of the channels in the dispenser, the viscosity of the composition, etc. In general, the density of the foam should be between about 0.002 and about 0.25 g/cc, preferably between about 0.01 and about 0.07 g/cc. Foam density is inversely related to foam creaminess so lower foam densities are preferred. i The mousse compositions herein can also be packaged in a pump-actuated non-aerosol dispenser of the so-called "pump-foamer" type which comprise a reservoir, a dispensing head, pump means, liquid/air mixing means and preferably homogenising means and non-return valve means. Highly preferred for use herein is a pump foamer pack as described in Japanese Utility Model 1-66900. In brief, the pump foam dispenser comprises a manually actuated, spring-mounted piston tube arranged for reciprocal, up and down movement within a air/liquid cylinder, wherein the piston tube and the upper large diameter part of the cylinder together act as an air pump and wherein the piston tub and the lower, small diameter part of the cylinder together act as a liquid pump. The liquid and air pumps are synchronized by the common piston mechanism. The pumping action is controlled by means of three check valves, a first check valve which regulates entry of liquid from the reservoir into the liquid cylinder, a second check valve which regulates entry of air into the air cylinder, and a third check valve which regulates discharge of liquid from the liquid cylinder to a liquid/air mixing chamber. The liquid/air mixing chamber preferably includes a homogenizing means which makes the generated foam more homogeneous and controls the consistency of the foam. The foam is then discharged as a uniform non-pressurized aerated foam through the dispensing head of the dispenser. In general, the density of the foam should be between about 0.002 and about 0.25 g/cc, preferably between about 0.01 and about 0.07 g/cc. Foam density can be controlled by regulating the air/liquid ratio of the dispenser which is preferably at least 20:1 , more preferably at least 40:1. A preferred method of regulating air/liquid ratio is by preaeratiπg the liquid entering the liquid cylinder, for example, by introducing a small air bleed hole in the dip-tube which connects the liquid cylinder to the liquid reservoir. Thus, introducing a 0.6 mm bleed hole at a point approximately 3 mm below the first check valve (ie. above the normal liquid level in the reservoir) increases the air to liquid ratio from approximately 20:1 up to about 50:1. The present compositions are emitted from the non-aerosol dispenser as a foam which is worked through the hair with the fingers or a hair styling implement and either left on the hair or rinsed out. 20 The present invention is illustrated by the following examples. Examples l-V Hair styling mousse compositions are prepared having the following ingredients (all levels on a weight % active basis): 1 - Vinylpyrrolidone/vinyl acetate copolymer supplied by BASF 2 - Vinylpyrrolidone/vinylimidazolium methochloride copolymer supplied by BASF as a 40% solution 3 - Cocamidopropylbetaine supplied by Goldschmidt as a 30% solution The hair styling mousse compositions of the above examples demonstrate superior foam quality and stability characteristics (good initial foam formation together with foam breakdown under shear) while at the same time being non- sticky and easily spreadable. The compositions also demonstrate excellent hair hold, feel and conditioning.
