Abstract
A cosmetic composition comprising an aqueous polymer emulsion in an amount of from 1 to 60% by weight in terms of the weight of solid contents of the cosmetic composition. The aqueous polymer emulsion is produced by polymerizing at least one polymerizable monomer having a double bond in the presence of a plasticizer or a film-forming auxiliary. This aqueous polymer emulsion ensures in the cosmetic composition excellent gloss, film stability, water repellency, and film-forming properties, and also ensures freedom from cosmetic crumbling due to sweat and sebum.
Claims16
A method of manicuring or pedicuring, which comprises applying to a nail a nail enamel composition, the nail enamel composition comprising:
- (i) a pigment;
- and
- (ii) an aqueous polymer emulsion in an mount, as a solid content, of from 1 to 60% by weight based on the total weight of the nail enamel composition,
- said aqueous polymer emulsion being produced by polymerizing at least one polymerizable monomer having a double bond in the presence of a plasticizer or film-forming auxiliary selected from the group consisting of cellosolves carbitols, acetates, alcohols, diols, esters, ethers and diethylbenzene, and in which the plasticizer or film-forming auxiliary is not removed from the emulsion except for any plasticizer or film forming auxiliary, if any, present in aggregates which may optionally be removed.
