Abstract: A (meth)acrylic acid/alkyl (meth)acrylate ester copolymer containing: 95.42 to 97.48% by mass of (meth)acrylic acid; 2.43 to 4.30% by mass of an alkyl (meth)acrylate ester, and 0.08 to 0.30% by mass of a compound having two or more ethylenically unsaturated groups. Use in cosmetics.

Abstract: A (meth)acrylic acid/alkyl (meth)acrylate ester copolymer containing constituents of 95.42 to 97.48% by mass of (meth)acrylic acid, 2.43 to 4.30% by mass of an alkyl (meth)acrylate ester of which alkyl group has 18 to 24 carbon atoms, and 0.08 to 0.30% by mass of a compound having two or more ethylenically unsaturated groups; and cosmetics blended with the copolymer. According to the copolymer of the present invention, a neutral viscous aqueous solution having a high viscosity can be formed even in the presence of an electrolyte in a relatively high concentration, without being affected by its temperature and electrolytic concentration; therefore, the copolymer of the present invention can be suitably used in cosmetics and the like.

Abstract: A cosmetic composition for eyelashes is disclosed which is excellent in make-up effects (long lash effect) such as making eyelashes appear longer and emphasizing eyes, and in long-lasting property of such make-up effects, exhibiting favorable usability, providing a uniform make-up film, and is also satisfactory in terms of stability. Provided is a cosmetic composition for eyelashes including: (A) polypropylene fibers having the thickness of 0.1 to 12 denier, and the length of 0.1 to 3 mm; and (B) an oil soluble resin.
