Sodium lauroyl sarcosinate

Sodium lauroyl sarcosinate (CAS 137-16-6), also known commercially as Sarkosyl NL, is a mild amino acid-derived surfactant used across personal care and food-contact applications.

It functions as a foaming agent, emulsifier, and cleansing active, offering effective surface activity with a gentler profile than conventional sulfate surfactants in various formulations.

In personal care formulations, it acts as a primary or co-surfactant in shampoos, facial cleansers, and toothpastes, delivering dense, stable foam while minimizing irritation to skin and mucous membranes.

Toothpaste manufacturers rely on it specifically for its compatibility with fluoride systems and its ability to reduce surface tension without disrupting active ingredient stability during the manufacturing process.

In shave gels and conditioning cleansers, it contributes to slip and emulsification, helping suspend oils and conditioning agents evenly throughout the formula for a superior consumer experience.

Food-contact and industrial cleaning applications also utilize it as a degreasing and wetting agent where low toxicity and biodegradability are procurement requirements for modern industrial standards.

Sodium lauroyl sarcosinate is supplied as a clear to pale yellow aqueous solution, typically at 30% active content, and as a dry powder or needle form for formulators requiring anhydrous processing.

Standard grades include cosmetic/personal care grade meeting industry purity benchmarks, with technical grade available for industrial cleaning uses to ensure cost-effective and high-performance results.
