Patent number: 6268454Abstract: The invention relates to a novel amino acid silicon polymer with good adhesion to the keratin layer of the skin, a method of preparing the amino acid silicon polymer, a cosmetic particles surface-treated with the amino acid silicon polymer, and a color cosmetic composition including the cosmetic particles. According to the present invention, the particles surface-treated up to 3% to the maximum with the amino acid silicon polymer prepared by reacting an amino acid and a functional silicon polymer in the manner of organic synthesis have water resistance and usability peculiar to silicon-treated pigments and take positive surface charges, thereby offering good adhesion to the skin and durability. Due to these characteristics, the cosmetic containing the surface-treated particles of the present invention is superior in the cosmetic effect to that containing the conventional surface-treated particles.Type: GrantFiled: February 17, 2000Date of Patent: July 31, 2001Assignee: Pacific CorporationInventors: Dong Hyuk Song, Yeong Jin Choi, Kil Joong Kim, Young Chul Lee
