PURPOSE:A cosmetic, containing a crosslinked proteinaceous high polymer obtained by reacting transglutaminase with protein in a liquid, and having good humectant property and remarkably improved extensibility. CONSTITUTION:A cosmetic obtained by incorporating a crosslinked high polymer prepared by reacting transglutaminase with protein, e.g. vegetable protein such as defatted oil seed, or animal protein such as milk protein or gelatin collagen, in the form of a mixture with water, oil-in-water type or water-in-oil type emulsion to give a highly viscous material or gelatinous material when the liquid contains >=2wt%, preferably >=5wt% protein or solutional material when the liquid contains <=2wt% protein with a cosmetic, etc. The amount of the crosslinked high polymer is 5-10% expressed in terms of dry material. The crosslinked high polymer incorporated with the cosmetic imparts moderate moisture to the skin or hair, and the skin or hair surface can be protected. EFFECT:Stable with prolonged action. |
