HYDROPHILIC POLYMER COMPOUND AND SKIN CARE PREPARATION OR COSMETIC MIXED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrophilic polymer compound that has more excellent sense of use than a conventional acrylic polymer compound, improves water retention ability and provides a skin care preparation and a cosmetic with moisture retention when mixed with the skin care preparation or the cosmetic.;SOLUTION: The hydrophilic polymer compound is obtained by copolymerizing one or more polymerizable monomerized pyroglutamic acids with another polymerizable nitrogen-containing monomer and has properties of being soluble in water or a water-alcohol solution and swelling when dissolved in water or a water-alcohol solution.;COPYRIGHT: (C)2011,JPO&INPIT
