I use this preservative im a number of formulas. The quality is very good. Haven’t had any spoilage. I would like to see the expiry date on the bottle or at least on the website though.

Description
Description
Zinc PCA is the zinc salt of L-Pyrrolidone Carboxylic Acid (PCA). It combines zinc, a mineral valued in cosmetic formulation for its astringent and deodorizing support, with PCA, a component of the skin’s natural moisturizing factor (NMF). Together, they help visibly reduce excess surface oil, support a more refined look in oily areas, and offer light skin-conditioning benefits in leave-on and rinse-off products.
Zinc PCA is water-soluble, easy to incorporate at low temperatures, and works beautifully in serums, gels, toners, lotions, spot treatments, and deodorant formats designed for oily or combination routines. It’s also a favorite in scalp care where lightweight formulas are preferred.
