CAS 15454-75-8 Zinc Pyrrolidone Carboxylic Acid Zinc PCA Cosmetic Grade Pyroglutamic Acid Zinc Salt

Description

Zinc Pyrrolidone Carboxylic Acid, commonly known as Zinc PCA, is the zinc salt of Pyrrolidone Carboxylic Acid (PCA), which is a natural component of human skin's Natural Moisturizing Factor (NMF). It is a white, free-flowing powder that is highly soluble in water. As a multifunctional active ingredient, it combines the exceptional moisture-binding capacity of PCA with the well-known sebum-regulating and antimicrobials benefits of zinc. This synergy makes it a cornerstone ingredient in modern cosmeceuticals and personal care formulations aimed at treating oily, acne-prone, and sensitive skin.

Specification

Key Features & Benefits

1. Potent Sebum Regulation: Zinc ions inhibit the activity of 5-alpha-reductase,  which stimulates sebum production. This makes it highly effective for oily and acne-prone skin.
2. Antimicrobials & Anti-Acne Activity: Exhibits strong antibacterial activity against Cutibacterium acnes (the bacteria responsible for acne), helping to reduce inflammation and prevent breakouts.
3. Superior Moisture Retention: As a component of the NMF, it is a powerful humectant, drawing and binding water from the atmosphere into the stratum corneum, improving skin hydration and barrier function.
4. Astringent & Pore-Refining: Provides a mild tightening effect, helping to reduce the appearance of enlarged pores.
5. Deodorant Properties: Effectively inhibits the growth of odor-causing bacteria on the skin, making it a popular active in natural deodorants.
6. Skin Compatibility: Excellent skin tolerance, non-irritating, and suitable for sensitive skin types.
7. Synergistic with Other Actives: Works well with other anti-acne ingredients (like salicylic acid, niacinamidess) and moisturizing agents.
