What Is L-Pyroglutamic Acid?

L-Pyroglutamic Acidis colorless crystal. The melting point is162-163 ° C, soluble in water, alcohol, acetone and glacial acetic acid, slightly soluble in ethyl acetate, insoluble in ether.

L-Pyroglutamic Acid Usage

1. Pyroglutamic Acid is one of the main components of skin natural moisturizing factor, and its moisturizing ability far exceeds that of glycerin and propylene glycol. It is non-toxic and non-irritating, and is an excellent raw material for modern skin care and hair care cosmetics.

2. Pyroglutamic Acid also inhibits the activity of tyrosine oxidase, thereby preventing the deposition of melanoid substances in the skin and whitening the skin.

3. Pyroglutamic Acid has a softening effect on keratin and can be used for nail cosmetics.

4. Pyroglutamic Acid and other organic compound-derived derivatives have special effects in surface activity, transparent brightening and the like.
