Stabilzation method of nano-sized emulsion using tocopheryl derivatives and external application for skin containing the same

A ceramide-like compound having properties of the natural ceramides are represented by the following formula (I), and a method for producing the same , and a cosmetic composition containing the same as an active ingredient:

Ceramide-like compounds having antioxidant property and a method for preparation thereof, and a cosmetic composition containing the same

Tocopherol derivatives and method for preparation thereof

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.
