Sodium Cocoyl Sarcosinate ●
TL;DR. This ingredient is a mild anionic surfactant used to cleanse, foam, and improve rinse-off feel in shampoos, face washes, body washes, and toothpastes. It is often chosen when a formula needs dense foam with less stripping than stronger sulfate-type cleansers.
What does Sodium Cocoyl Sarcosinate do in a cosmetic formula?
This ingredient is a mild anionic surfactant used to cleanse, foam, and improve rinse-off feel in shampoos, face washes, body washes, and toothpastes. It is often chosen when a formula needs dense foam with less stripping than stronger sulfate-type cleansers.
Is Sodium Cocoyl Sarcosinate clean?
From a clean-beauty perspective, this ingredient is generally well accepted and is not a common restricted-list concern. The main quality-control note is impurity management, especially residual amines and nitrosamine-related specifications from processing.
Is Sodium Cocoyl Sarcosinate sustainable?
This material is commonly made from coconut or palm-kernel fatty acids combined with a modified amino-acid building block, so sourcing depends on the fatty-acid supply chain. It is considered readily biodegradable and has a lower persistence profile than many non-biodegradable conditioning or film-forming materials.
Is Sodium Cocoyl Sarcosinate COSMOS-approved?
It is generally permitted in COSMOS-natural formulas and can be used in COSMOS-organic products when supplier documentation and processing meet the standard. Its Green Chemistry fit is solid but not perfect, with renewable fatty-acid content and good biodegradability balanced by chemical conversion steps and feedstock traceability needs.
How does Sodium Cocoyl Sarcosinate work chemically?
The molecule is an acyl amino-acid surfactant with a fatty tail and an anionic carboxylate head, which gives it cleansing power plus relatively mild skin feel. It is typically used in rinse-off systems at a few percent active matter, performs best around mildly acidic to neutral pH, and is often blended with amphoteric or nonionic surfactants to tune foam, viscosity, and irritation profile.
