Cosmetic Raw Materials

It is used for preparing succinic acid, pentanediol, tetrahydrofuran, pyran, etc. it is also used as a solvent for coatings, resins and oils. In the printing and dyeing industry, it is used as lubricant, dispersant, decolorizing and deodorizing agent of drugs, as well as raw materials for organic synthesis such as plasticizer, herbicide and pesticide. Tetrahydrofuran methyl bromide was obtained by bromination of tetrahydrofuran alcohol, and sodium tetrahydrofuran methyl thiosulfate was prepared by replacement of sodium thiosulfate.

In human skin, there is a kind of water-soluble substance with moisturizing function natural moisturizing factor, which is composed of amino acids (40%), pyroglutamic acid (12%), inorganic salts (18.5% of Na, K, CA, Mg, etc.) and other organic substances (29.5%). Therefore, pyroglutamic acid is one of the main components of skin natural moisturizing factor, and its moisturizing ability is far more than glycerol and propylene glycol. It is a good raw material for modern skin care and hair care cosmetics. Pyroglutamic acid can also inhibit the activity of tyrosine oxidase, thus preventing the deposition of "melanoid" substances in the skin and whitening the skin. It has softening effect on cutin and can be used in nail cosmetics. In addition to its application in cosmetics, L-pyroglutamic acid can also form derivatives with other organic compounds, which have special effects in surface activity, transparency and brightness. It can also be used as surfactant and detergent; Chemical reagent for resolution of racemic amine; Organic intermediates.

Epigallocatechin gallate (EGCG), also known as epigallocatechin-3-gallate. Gallocatechol is an ester formed by gallocatechol and gallic acid, belonging to catechin. EGCG is the most abundant catechin in most famous teas. It could also be antioxidants, which could treat many diseases, including cancer. EGCG is found in green tea, but not in black tea. Because EGCG in black tea is transformed into thearubigin.

Polyquaternary ammonium salt amphoteric polymer has good compatibility with cationic, non-ionic and amphoteric surfactants, good smoothness, moisture, anti knotting and excellent dry and wet combing. It can enhance wire drawing and thickening of all kinds of liquids. It can enhance the moisturizing and slippery feeling of the skin and reduce the tension of the skin after cleaning.
