Sodium sarcosinate

Sodium sarcosinate (CAS 4316-73-8), also known as sarcosine sodium salt, is the sodium salt form of the naturally occurring amino acid derivative sarcosine. It functions as a chelating agent, pH buffer, and mild surfactant across personal care and food-grade applications.

In personal care formulations, it acts as a chelating agent to sequester hard water ions, improving the stability and performance of shampoos, cleansers, and skin care products. Its buffering capacity makes it useful in oral care products.

In these oral care applications, it helps maintain pH consistency in toothpaste and mouthwash formulations. In cosmetic systems, it contributes moisturizing properties that support skin conditioning in leave-on and rinse-off products.

Food-grade applications include use as a processing aid and buffering agent in select formulations where amino acid-derived additives are required. This versatile chemical is often utilized for its high purity and compatibility with various ingredients.

Sodium sarcosinate is supplied as a white crystalline powder or as an aqueous solution, depending on the supplier and intended application. Food-grade and cosmetic-grade specifications are the most commercially available for global distribution.

Technical-grade material is also offered for industrial chelation uses. Buyers should confirm concentration and grade designation when sourcing solution forms, as these vary across suppliers to meet specific manufacturing requirements.
