Description

2-Pyrrolidone-5-Carboxylic Acid Sodium Salt is the sodium salt derivative of PCA (Pyrrolidone Carboxylic Acid), a key endogenous moisturizing factor. This compound is valued for its excellent water solubility, stability, and skin-identical properties, making it a superior humectant and conditioning agent. It is primarily sought after by manufacturers in the cosmetics, personal care, and pharmaceutical industries for formulating high-performance skincare, haircare, and topical products.

Application

• Cosmetic & Skincare Formulations: As a powerful moisturizing agent in creams, lotions, serums, and anti-aging products due to its natural presence in the skin's Natural Moisturizing Factor (NMF).
• Hair Care Products: Used in shampoos, conditioners, and treatments to improve hair hydration, manageability, and shine.
• Pharmaceutical Topicals: Incorporated into medicated creams, ointments, and dermatological preparations for its moisturizing and skin barrier-supporting properties.
• Biochemical Research: Serves as a reagent or standard in studies related to skin biology, moisturization mechanisms, and cosmetic science.
• Industrial Applications: Potential use as a specialty surfactant or conditioning agent in niche industrial formulations.
