    摘要: An object of the present invention is to provide the tocopherol derivatives represented by the following formula (I), and their salts: Wherein, R1, R2 and R3 are H or methyl group, and at least one positions selected from group consisting of the R1, R2 and R3 positions are methyl group; and, A is CH2—CH(CH3)— or CH═C(CH3)— The other object of the present invention is to provide a method for preparing the above tocopherol derivatives. The tocopherol derivatives is prepared by reacting tocopherol with phosphorous oxychloride in an equivalent ratio of 1:1˜1.3, in presence of an organic base, in an organic solvent; reacting the tocopherol dichlorophosphate produced by the above reaction with 3-aminopropanol in presence of an organic base, in an organic solvent; and, hydrolyzing the above products. The tocopherol derivatives according to the present invention can be hydrolyzed by biological enzymes in a living body to produce tocopherol and 3-aminopropane phosphate. And they can induce physiological activities including recovery of injured skin, prevention from aging of bio-membrane, etc. Also, the tocopherol derivatives according to the present invention have improved stability, safety to skin and anti-oxidant effect superior to preceding tocopherol and its derivatives.

    摘要: 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.
