Sodium Lauroyl Sarcosinate (Sarkosyl) is a sodium salt of Lauroyl Sarcosinate, an ester of Lauroyl alcohol and Sarcosine amino acid. It is a secondary surfactant in a wide range of cleansing applications. Sarkosyl can work with mild surfactants like betaines or replace them as it is also an alkyl-amino acid type surfactant similarly gentle and effective.
Milder than Mono Alkyl Phosphates, Sodium Lauroyl Sarcosinate exhibits superior mildness and lower irritation potential. In addition, it has an excellent sensory profile, leaving a long-lasting soft and silky after-feel on the skin. Foaming properties are comparable with betaines and alkyl ether sulfates.
Sarkosyl is a safe, non-toxic, and mild cleansing agent with excellent cleansing/foaming performance even in hard water, thanks to ideal compatibility with skin and hair. It is also a readily biodegradable and environmentally friendly ingredient.
It is permitted in baby care cleansing applications such as head-to-toe shampoos. In addition, sodium Lauroyl Sarcosinate is a common ingredient in high-end hair shampoo, body and face washes, shower gels, facial cleansers, and toothpaste.
