1. Skin Care
L-Pyroglutamic acid is one of the main components of natural skin moisturizing factors, its moisturizing ability is far more than glycerol and propylene glycol, and non-toxic, non-stimulating, is a modern skin care, hair care cosmetics excellent raw materials.
L-Pyroglutamic acid also inhibits the activity of tyrosine oxidase, thereby preventing the deposition of "melanoid" substances in the skin, which has a whitening effect on the skin.
2. Daily chemical industry
In addition to its application in cosmetics, L-pyroglutamate can also form derivatives with some other organic compounds, which have special effects on surface activity, transparency and brightness.It can also be used as a surfactant, for detergents;
