PROBLEM TO BE SOLVED: To provide a composition capable of being used in cosmetic fields, making it possible to stabilize a hydrophilic component which is unstable in an oxidizing medium in the composition, comfortable when used, without causing any irritation on the skin after used, and capable of being suitably compromised with restrictions on industrially conducting production processes thereof. SOLUTION: The composition for local application contains at least one oxidation-sensitive hydrophilic component and at least one maleic anhydride copolymer in a physiologically acceptable medium containing an aqueous phase, wherein the maleic anhydride copolymer comprises one or more maleic anhydride comonomers and one or more comonomers selected from vinyl acetate, vinyl alcohol, vinylpyrrolidone, a 2-20C olefin, and styrene. The maleic anhydride copolymer is used for stabilizing the oxidation-sensitive hydrophilic component especially in the aqueous phase. COPYRIGHT: (C)2004,JPO
