Description
Sodium lauroyl sarcosinate (CAS 137-16-6) is an amino acid-derived anionic surfactant commercially known under trade names including Sarkosyl NL, Sarkosyl NL 100, Medialan LL 99, Gardol, and Compound 105. It carries no E-code designation and is classified under HS code 34021190.
In personal care formulations, it functions as a mild foaming and cleansing agent by lowering interfacial tension between oils and water, making it suitable for toothpastes, shampoos, and facial cleansers where skin compatibility is a formulation priority. In food-contact and oral care applications, it also acts as an emulsifier, stabilising oil-in-water systems at low use concentrations.
The material is supplied as a white powder and is available in cosmetic and technical grades. It is subject to REACH registration requirements within the EU and is handled by suppliers maintaining compliance documentation accordingly. Procurement teams should confirm grade specification and packaging format directly with the supplier.
