To provide an acrylic silicone graft copolymer capable of effectively exerting a function in a composition for external application containing various oily components such as a natural oil, a hydrocarbon oil, ester oil and a silicone oil, and a composition for external application containing the acrylic silicone graft copolymer. A composition for external application including an acrylic silicone graft copolymer, which contains 2 to 25 mass % of a constitutional unit represented by formula (I), 55 to 85 mass % of a constitutional unit represented by formula (II) and 2 to 20 mass % of a constitutional unit represented by formula (III). wherein R1 is an alkyl group having 1 to 4 carbon atoms; R2 is an alkylene group having 2 to 10 carbon atoms; and n is an integer of 1 to 100.

Composition for external application and method for producing the same

Provided is a water repellent composition which does not use a fluorine-containing monomer, especially a fluoroalkyl group-containing monomer. A water repellent composition which contains (1) (a) a polymer which has a repeating unit derived from an amide group-containing monomer that is represented by formula: (wherein R1 represents an organic residue having an ethylenically unsaturated polymerizable group; R2 represents a hydrocarbon group having 7-30 carbon atoms; and R3 represents a hydrocarbon group having 1-5 carbon atoms) in an amount of 2-100% by weight relative to the polymer, and (2) a liquid medium.
