Usage And Synthesis
Characteristics and Application

L-pyroglutamic acid is an amino acid that occurs naturally in the body. It is present in the brain, spinal fluid, skin and blood.
pyroglutamic acid is one of the major components of natural moisturizing factor of the skin, its moisturizing ability is far stronger than glycerin and propylenee glycol. Moreover, it is non-toxic, non-irritating, and is an excellent raw material for modern skin care, and hair care cosmetics. Pyroglutamic acid also has inhibitory effect on the tyrosine oxidase activity, and thus preventing "melanoidins" substance from being deposited in the skin, and having a whitening effect on the skin. It has a keratin softening effect which can be used in nail cosmetics.
In addition to be applied in cosmetics, L-pyroglutamic acid derivatives can also have reaction with a number of other organic compounds for synthesis of derivatives. It also has some special effect on the surface activity and brilliant effect. Moreover, it can also be used as surfactants for detergents; as a chemical reagent, it can be used for the resolution of racemic amines; it can also be used as a kind of organic intermediates.
