Two component interactive emulsion product

Abstract

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.

         25 . The composition according to  claim 20  wherein at least about 60% by weight of the total amount of the ionic surfactants in said first and said second parts precipitate upon mixing. 
     
     
         26 . The composition according to  claim 20  wherein at least about 90% by weight of the total amount of the ionic surfactants in said first and said second parts precipitate upon mixing. 
     
     
         27 . The composition according to  claim 20  wherein the total molar ratio of the ionic surfactant(s) in the first emulsion composition ranges from about 0.5 to 1 to about 2:1 the molar ratio of the ionic surfactant(s) in the second emulsion composition. 
     
     
         28 . 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. 
     
     
         29 . The composition according to  claim 28  wherein said ionic polymer in said first emulsion is cationic and wherein said ionic polymer in said second emulsion composition is anionic. 
     
     
         30 . The composition according to  claim 28  wherein said surfactant in said first emulsion composition is a cationic surfactant. 
     
     
         31 . The composition according to  claim 28  wherein said surfactant in said second emulsion composition is an anionic surfactant. 
     
     
         32 . The composition according to  claim 29  wherein said cationic polymer is a surfactant. 
     
     
         33 . The composition according to  claim 29  wherein said anionic polymer is a surfactant. 
     
     
         34 . The composition according to  claim 28  wherein said surfactant in said first emulsion composition and/or said surfactant in said second emulsion composition are nonionic. 
     
     
         35 . The composition according to  claim 28  wherein said composition is a personal care composition. 
     
     
         36 .
