Zinc PCA

Zinc PCA (CAS 15454-75-8), also known as Zinc Pidolate, PCA-ZN, and ZINCIDONE, is the zinc salt of pyroglutamic acid. It carries no assigned E-code and is classified within the Salts & Minerals category. The compound combines the biological activity of zinc with the skin-conditioning properties of the PCA anion.

In personal care formulations, Zinc PCA functions as a humectant by attracting and retaining moisture within the stratum corneum, while its zinc component delivers antioxidant stabilization that helps regulate sebum production in anti-acne and oily-skin products. In pharmaceutical topical preparations, it supports wound-healing and antimicrobial activity at the skin surface.

Zinc PCA is supplied in cosmetic and pharmaceutical grades compliant with REACH registration requirements applicable to the European market. Procurement quantities are available from laboratory scale through bulk industrial volumes. Buyers should confirm grade-specific documentation, including safety data sheets and certificates of analysis, at the point of inquiry.
