Abstract
Abstract Liquid or paste eye makeup preparations containing, as a film forming agent, an aqueous emulsion of at least one copolymer of one or more alkyl acrylates having from C4 to C18 alkyl groups in the ester portion and one or more alkyl methacrylates having from C1 to C4 alkyl groups in the ester portion is provided. This copolymer emulsion can be advantageously incorporated into eye makeup preparations, such as an eye liner and mascara, to formulate the water resistant, rub-proof and stain-proof liquid or paste eye makeup preparation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
In an aqueous dispersion type eye makeup preparation comprising from 20 to 50% by weight of a film forming agent, from 1 to 10% by weight of at least one humectant, from 5 to 30% by weight of at least one pharmaceutically acceptable finely divided inorganic pigment, from 0.1 to 5% by weight of at least one surface active agent, from 0.1 to 3% by weight of at least one thickener, from 0.5 to 5% by weight of at least one plasticizer and a balance of water; wherein the improvement comprises that said film forming agent consists essentially of an aqueous emulsion of at least one member selected from the group consisting of copolymers derived from monomer mixtures of 30 to 80% by weight, of at least one alkyl acrylate having from C 4 to C 18 alkyl groups in the ester portion and 70 to 20% by weight of at least one alkyl methacrylate having from C 1 to C 4 alkyl groups in the ester portion.
Claim 2
Dependent Claim
168 words
In an aqueous dispersion type eye makeup preparation comprising from 20 to 50% by weight of a film forming agent, from 1 to 10% by weight of at least one humectant, from 5 to 30% by weight of at least one pharmaceutically acceptable finely divided inorganic pigment, from 0.1 to 5% by weight of at least one surface active agent, from 0.1 to 3% by weight of at least one thickener, from 0.5 to 5% by weight of at least one plasticizer and a balance of water; wherein the improvement comprises that said film forming agent consists essentially of an aqueous emulsion of at least one member selected from the group consisting of copolymers derived from monomer mixtures of 30 to 80% by weight, of at least one alkyl acrylate having from C 4 to C 18 alkyl groups in the ester portion and 70 to 20% by weight of at least one alkyl methacrylate having from C 1 to C 4 alkyl groups in the ester portion.
