A cosmetic composition comprising copolymer, non-volatile oil and glossy oil is provided to protect keratin materials, especially lips, and improve use pleasance, continuance of protection effects and lip-glossing effects through just one time application. A cosmetic composition comprises a copolymer containing at least one alkyl metacrylate, alkyl acrylate and acrylic acid monomer; a non-volatile oil having a hydrocarbon chain containing 16 carbon atoms or more and mole weight of 650g/mol; and glossy oil having mole weight of 650g/mol, wherein the copolymer is a block copolymer containing at least one first block obtained from an acrylate monomer represented by the formula of CH2=CH-COOR2 and a metacrylate monomer represented by the formula of CH2=C(CH3)-COOR'2, and at least one second block obtained from acrylic acid monomer and another monomer having glass transition temperature of 20 deg. C or less in which R2 is C4-C12 cycloalkyl group and R'2 is C4-C12 cycloalkyl group. |
