Abstract

Abstract Disclosed are facial cleansing compositions in the form of an oil-in-water emulsion which contain specific surfactants with an HLB above about 10 in combination with specific polyalphaolefins and specific carboxylic copolymers which provide improved cleansing efficacy as well as improved rinsability and improved skin feel (such as a nongreasy feeling).

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 207 words
A cleansing composition for removing make-up and the like in the form of an oil-in-water emulsion comprising: a. from about 0.5% to about 10% of a surfactant with an HLB greater than about 10 selected from the group consisting of anionic, nonionic, zwitterionic, amphoteric and ampholytic surfactants and mixtures thereof; b. from about 2% to 30% of polyalphaolefin of the formula: R₁-C=C-R₂ wherein R₁ and R₂ are independently from about C₂₀ to about C₃₀ alkyl, wherein said polyalphaolefin has a viscosity of from about 2 to about 4 centistokes at 100°C; and c. from about 0.025% to about 0.75% of a carboxylic copolymer comprising polymers of a monomeric mixture containing 95.9 to 98.8 weight percent of an olefinically unsaturated carboxylic monomer selected from the group consisting of acrylic, methacrylic and ethacrylic acids, about 1 to about 3.5 weight percent of an acrylate ester of the formula: wherein R is an alkyl radical containing 10 to 30 carbon atoms and R₁ is hydrogen, methyl or ethyl, and 0.1 to 0.6 weight percent of a polymerizable cross-linking polyalkenyl polyether of a polyhydric alcohol containing more than one alkenyl ether group per molecule wherein the parent polyhy­dric alcohol contains at least 3 carbon atoms and at least 3 hydroxyl groups.
Claim 2
Dependent Claim 207 words
A cleansing composition for removing make-up and the like in the form of an oil-in-water emulsion comprising: a. from about 0.5% to about 10% of a surfactant with an HLB greater than about 10 selected from the group consisting of anionic, nonionic, zwitterionic, amphoteric and ampholytic surfactants and mixtures thereof; b. from about 2% to 30% of polyalphaolefin of the formula: R₁-C=C-R₂ wherein R₁ and R₂ are independently from about C₂₀ to about C₃₀ alkyl, wherein said polyalphaolefin has a viscosity of from about 2 to about 4 centistokes at 100°C; and c. from about 0.025% to about 0.75% of a carboxylic copolymer comprising polymers of a monomeric mixture containing 95.9 to 98.8 weight percent of an olefinically unsaturated carboxylic monomer selected from the group consisting of acrylic, methacrylic and ethacrylic acids, about 1 to about 3.5 weight percent of an acrylate ester of the formula: wherein R is an alkyl radical containing 10 to 30 carbon atoms and R₁ is hydrogen, methyl or ethyl, and 0.1 to 0.6 weight percent of a polymerizable cross-linking polyalkenyl polyether of a polyhydric alcohol containing more than one alkenyl ether group per molecule wherein the parent polyhy­dric alcohol contains at least 3 carbon atoms and at least 3 hydroxyl groups.
Claim 3
Dependent Claim 50 words
A cleansing composition according to Claim 1 which comprises from about 0.5% to about 5% of the surfactant component and wherein said surfactant is selected from the group consisting of anionic surfactants, nonionic surfactants and mixtures thereof and which further comprises from about 5% to about 15% of the polyalpha­olefin.
Claim 4
Dependent Claim 33 words
A cleansing composition according to Claim 2 which further comprises from about 1% to about 30% of a highly branched hydro­carbon of the formula: wherein n is an integer from 1 to 225.
Claim 5
Dependent Claim 31 words
A cleansing composition according to Claim 3 which comprises from about 1% to about 10% of the highly branched hydrocarbon compo­nent and wherein n is an integer from 1 to 16.
Claim 6
Dependent Claim 42 words
A cleansing composition according to Claim 4 which comprises from about 0.5% to about 2% of the surfactant component and from about 1% to about 5% of the highly branched hydrocarbon component and wherein n is an integer from 1 to 4.
Claim 7
Dependent Claim 19 words
A cleansing composition according to Claim 5 which comprises from about 8% to about 11% of the polyalphaolefin component.
Claim 8
Dependent Claim 19 words
A cleansing composition according to Claim 6 which further comprises from about 0.05% to about 10% of an emulsifier.
Claim 9
Dependent Claim 19 words
A cleansing composition according to Claim 7 which comprises from about 2% to about 8% of the emulsifier component.
Claim 10
Dependent Claim 19 words
A cleansing composition according to Claim 8 which further comprises from about 2% to about 10% of an emollient.
Claim 11
Dependent Claim 26 words
A cleansing composition according to Claim 9 wherein said emol­lient is selected from the group consisting of volatile silicone oils and non-volatile emollients and mixtures thereof.
