The present invention describes, in one aspect, the use of two oppositely charged surfactants as the primary emulsifiers in two separated parts of a product. The emulsifiers are chosen such that when the two parts of the emulsion product are mixed, the emulsifiers react to form water insoluble compounds that are no longer able to function as emulsifiers, thus, the oil phase of the emulsion is precipitated onto the skin along with the emulsifier reaction product. Since none of the deposited materials are water soluble, or capable of functioning as emulsifiers, the deposited oil phase is extremely resistant to being washed off. This technology finds applications in hand and body creams and lotions, baby care products, sunscreens, skin protective products, makeup systems, and automotive and furniture polishes.
A method of applying a water wash-off resistant, aesthetically pleasing, two part emulsion product comprising combining two emulsion products at the point of application on a surface, wherein one of the emulsions comprises an effective amount of an anionic emulsifier and the other emulsion comprises an effective amount of a cationic emulsifier.
A composition in two parts, a first part comprising a first emulsion composition comprising an oil, water and at least one surfactant and a second part comprising a second emulsion composition comprising an oil, water and an least one surfactant wherein when said two parts are mixed and applied to a keratinous surface, a majority by weight of the surfactants in said first and said second emulsion compositions precipitate out of the emulsion onto the keratinous surface, leaving behind a water-resistant film surface composition.
A composition in two parts, a first emulsion composition comprising an oil, water, at least one surfactant and at least one ionic polymer and a second emulsion composition comprising an oil, water, at least one surfactant and at least one ionic polymer wherein when said two parts are mixed and applied to a keratinous surface, a majority by weight of the surfactants and a majority by weight of the ionic polymers in said first and second emulsion compositions precipitate out of the emulsion onto the keratinous surface, leaving behind a water-resistant film surface composition.
