Introduction

Product name L-Pyroglutamic acid
CAS.No98-79-3
MFC5H7NO3
MW129.11
EINECS202-700-3

Function
L-Pyroglutamic acid is one of the main components of the skin's natural moisturizing factor, and its moisturizing ability far exceeds that of glycerin and 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 has an inhibitory effect on the activity of tyrosine oxidase, thereby preventing the deposition of "melanoid" substances in the skin and has a whitening effect on the skin. It has a softening effect on keratin and can be used in nail cosmetics. In addition to its application in cosmetics, L-pyroglutamic acid can also form derivatives with other organic compounds, and has special effects in terms of surface activity, transparency and brightening effect. It can also be used as a surfactant for detergents; chemical reagents for the resolution of racemic amines; organic intermediates.
