Human skin contains a kind of moisturizing functional water-soluble substances-the natural moisturizing factor, roughly consisting of amino acids (40%), pyroglutamic acid (12%), inorganic salts (Na, K, Ca, containing 18.5% Mg, etc.), and other organic matter (including 29.5%). So, pyroglutamic acid is one of the major components of natural moisturizing factor of the skin, its moisturizing ability is far stronger than glycerin and propylene 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.

L-pyroglutamic acid has its scientific name being L-2-pyrrolidone-5-carboxylic acid. Precipitation from ethanol and petroleum ether mixture were colorless orthorhombic bipyramid crystals with the melting temperature being 162~163 °C. It is soluble in water, alcohol, acetone and acetic acid, slightly soluble in ethyl acetate, and insoluble in ether. Specific rotation-11.9 ° (c = 2, H2O). It is produced from 42% aqueous solution of glutamic acid which subjects to heating dehydration, concentration, crystallization, washing and drying to obtain L-pyroglutamic acid.

(S)-(-)-2-Pyrrolidinone-5-carboxylic acid is used as a building block for pharmaceuticals and asymmetric synthesis. It Is also used as a resolving agent for chiral bases and in an efficient synthesis of quinolizidine and indolizidine alkaloids.
