Sodium Lauryl Sarcosinate

Sodium Lauroyl Sarcosinate is a mild, anionic surfactant derived from sarcosine (an amino acid) and coconut fatty acids. It creates rich, creamy foam and provides excellent cleansing without stripping the skin or hair.

It is a popular choice for gentle shampoos, facial cleansers, baby washes, toothpastes, and sulfate-free formulations.
