Beschreibung
Zusammenfassung:	A method of designing a film-forming agent for cosmetics, which can form a film having excellent water resistance and excellent sebum resistance while also having high washability, is provided. The method is also useful for designing a cosmetic containing the film-forming agent. The film-forming agent comprises a copolymer, which is formed by polymerizing a monomer composition. The monomer composition comprises: (A) an unsaturated monomer having at least one polysiloxane structure in the molecule; and (B) an unsaturated monomer having at least one acidic group or salt thereof in the molecule; wherein monomer (A) is present in an amount of at least 30 wt % relative to the weight of to the monomer composition.
