Гликолевая кислота

Glycolic acid 1)colorless crystal 2)purity:99%min 3)Due to its excellent capability to penetrate , glycolic acid finds applications in skin care products, most often as a chemical peel performed by a dermatologist in concentrations of 20 to 70% or at-home kits in lower concentrations between 10 and 50%. In addition to concentration, pH also plays a large part in determining the potency of glycolic acid in solution. Physician-strength peels can have a pH as low as 0.6 (strong enough to completely keratolyze the epidermis), while acidities for home peels can be as high as 2.5. Glycolic acid is used to improve the skin's appearance and texture. It may reduce wrinkles, scarring, and improve many other skin conditions, including , , and . Once applied, glycolic acid reacts with the upper layer of the , weakening the binding properties of the lipids that hold the dead skin cells together. This allows the to be exfoliated, exposing live skin cells. 4)Glycolic acid is also a useful intermediate for organic synthesis, in a range of reactions including: oxidation-, and long chain . It is used as a in the preparation of and other biocompatible copolymers (e.g. ). Among other uses this compound finds employment in the textile industry as a and agent, in food processing as a agent and as a preservative. Glycolic acid is often included into , solvents and additives for ink and paint in order to improve flow properties and impart gloss
