CAS 137-16-6PubChem CID 23668817

Sodium Lauroyl Sarcosinate

Lauroyl sarcosine is a condensation product of natural fatty acids with sarcosine, which is a natural amino acid found in muscles and other body tissues. Acyl sarcosines are considered modifiŽed fatty acids in which the hydrocarbon chains are interrupted by an amidomethyl group in the alpha position. They are used as hair-conditioning agents and surfactant-cleansing agents in cosmetics, as well as to improve wetting and penetration of topical pharmaceutical products. Acyl sarcosines and their sodium salts are also used in the metal finishing and processing industries for their crystal modifying, anti-rust, and anti-corrosion properties.

Function

ANTISTATIC: Preventing and/or reducing static electricity by neutralising electrical charge on surfaces.
CLEANSING: Helping to keep the body surface clean.
FOAMING: Trapping numerous small bubbles of air or other gas within a small volume of liquid by modifying the surface tension of the liquid.
HAIR CONDITIONING: Enhancing the appearance and feel of hair. Leaving the hair easy to comb, supple, soft and shiny and/or imparting volume, lightness, gloss, texture, etc.
SKIN CONDITIONING: Maintaining the skin in good condition.
SURFACTANT - CLEANSING: Wetting body surfaces, emulsifying or solubilizing oils, and suspending soil (generally, such ingredients contribute to the foaming and lathering properties of cleansing products).
SURFACTANT - EMULSIFYING: Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.
VISCOSITY CONTROLLING: Increasing or decreasing the viscosity (thickness) of cosmetics.
