Zinc pidolate

Zinc pidolate (CAS 15454-75-8), also known as Zinc PCA and zinc pyroglutamate, is the zinc salt of pyroglutamic acid. It is a naturally occurring amino acid derivative found in skin and used across personal care and pharmaceutical formulations.

This ingredient serves as a bioavailable zinc source that combines mineral supplementation with moisture-retention activity. In skincare, it functions as a sebum-regulating and moisturizing active in anti-acne creams and toners.

Its affinity for keratin supports targeted delivery in oily-skin treatments. Hair care formulators incorporate it into scalp serums and anti-dandruff products to control sebaceous secretion and support scalp condition.

Oral supplement manufacturers use it as a well-tolerated, bioavailable zinc source in tablets and capsules. It is preferred where gastrointestinal compatibility is a formulation priority for the end consumer.

It also appears in topical pharmaceutical preparations targeting skin barrier support and wound-adjacent care. The material is supplied as a white to off-white crystalline powder for various industrial applications.

It is available in cosmetic-grade and pharmaceutical-grade specifications. The latter conforms to purity standards appropriate for oral and topical drug products such as USP or Ph.Eur. requirements.

Packaging typically ranges from kilogram-scale bags to bulk quantities suited for industrial formulation. Our supply chain ensures consistent quality and availability for large-scale manufacturing needs.
