Sodium PCA

Chemical Formula:


Sodium-2-pyrrolidone carboxylate


Pale yellow clear liquid


Sodium PCA is hygroscopic, attracting moisture from the air. It is used as a moisturizer (humectant) for hair and skin care products.

It is a stronger hydrating agent than the traditional compounds used for this purpose, such as glycerine, propylene glycol, or sorbitol.
