Sodium Pidolate

Sodium Pidolate (CAS 28874-51-3), also known as Sodium Pyroglutamate, is the sodium salt of pyroglutamic acid and a naturally occurring component of the skin's natural moisturizing factor (NMF).

It functions as a humectant and moisture-retention agent across personal care, pharmaceutical, and food applications. In cosmetic formulations, it is incorporated into moisturizers, serums, and hair conditioners.

The material binds water within the skin or hair matrix, improving hydration performance. Pharmaceutical manufacturers use it as a stabilizing excipient in topical preparations and oral formulations where moisture regulation affects shelf life.

In food and nutrition applications, it acts as a flavor enhancer and stabilizer in processed foods, functional beverages, and nutritional supplements. It also appears in professional skincare actives and amino acid-based treatments.

These products target dry or compromised skin conditions effectively. Sodium Pidolate is supplied as a white crystalline powder or in aqueous solution at various concentrations to meet specific manufacturing requirements.

Standard grades include cosmetic/personal care grade and pharmaceutical grade, with material typically conforming to USP or in-house specifications depending on the intended application for the final product.

Food-grade material is available for nutrition and flavoring uses. Buyers should confirm grade-specific documentation, including CoA and residual solvent data, at the sourcing stage to ensure compliance with all safety standards.
