Sarcosine
What is Sarcosine?
Sarcosine, chemically known as N-methylglycine, is a naturally occurring amino acid derivative found in human muscles, liver, and certain foods like eggs. It features a simple structure with a methyl group attached to glycine. In cosmetics, it falls under skin conditioning agents, appearing in moisturizers, lotions, cleansers, and hair products. Sarcosine functions by binding moisture to the skin, enhancing flexibility and smoothness through interactions with lipids and proteins. Its mild surfactant action supports gentle cleansing, while buffering and chelating properties stabilize formulations. Biocompatible and water-soluble, it integrates seamlessly into water-based products, mimicking natural skin components to promote a supple feel without heaviness. Synthetically produced for purity, it suits various skin types in everyday routines.
