PURPOSE:To prepare a film-type packing agent having high aging stability and excellent applicability and releasability, by compounding a graft polymer composed of fibroin and a polymer of an anionic monomer or a nonionic monomer, with polyvinyl alcohol, water, and ethyl alcohol. CONSTITUTION:The objective packing agent consists of 0.01-1.0wt% fibroingraft polyer, 3-20wt% polyvinyl alcohol, 2-20wt% ehtyl alcohol, and the residual part of water. The fibroin-graft polymer is pref. composed of 60-95wt% polymer composed of an anionic monomer of e.g. formulaI(R1 is H or CH3; A is H, alkali metal, Al, etc.), 0-20wt% polymer composed of a nonionic monomer of formula II (B is -CONH2, -OCOCH3, etc.) and 5-40wt% fibroin. The packing agent forms a film in a short time, supplies moderate moisture to the skin keeps the moisture of the skin, and gives moist and pleasant feeling the skin. |
