PCA ZN
Name and spec: PCA-Zn （Zinc,bis(5-oxo-L-prolinato)- (8CI)）99%
CAS: 15454-75-8
Appearance: white powder
PCA zinc is a product of the combination of zinc and the natural moisturizing factor "pyrrolidone carboxylic acid (PCA for short)". PCA, the full name of which is pyrrolidone carboxylic acid (converted from glutamic acid), exists in the stratum corneum and is an important component of the natural moisturizing factor (NMF) inherent in the skin. NMF can bind moisture in the stratum corneum, keep the skin soft and smooth, and maintain a healthy barrier. Therefore, PCA zinc not only has the antibacterial, anti-sebum secretion, and anti-inflammatory effects of zinc, but also has the function of keeping the stratum corneum hydrated and maintaining a healthy barrier because it contains PCA. PCA zinc is very safe as a cosmetic raw material and has good antibacterial and astringent properties.
