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.
