Function:
L-Pyroglutamic Acid is 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.
Application:
- 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.
- Pyroglutamic Acid also inhibits the activity of tyrosine oxidase, thereby preventing the deposition of melanoid substances in the skin and whitening the skin.
- Pyroglutamic Acid has a softening effect on keratin and can be used for nail cosmetics.
- Pyroglutamic Acid and other organic compound-derived derivatives have special effects in surface activity, transparent brightening and the like.
Storage:
Stored in a cool dry and ventilated place.
