Sodium Palmitoyl Sarcosinate Description
Sodium palmitoyl sarcosinate is the salt of palmitoyl sarcosinate, which is derived from the amino acid derivative sarcosine. In cosmetics, sodium palmitoyl sarcosinate has hydrating and, when used in higher amounts, gentle cleansing properties. It may be animal-derived, synthetic, or derived from plants (Paula's Choice uses the latter). It is considered safe as used in cosmetics where concentrations up to 5% have been evaluated. Generally, the sarcosinate should not be used in loose powder products due to the risk of particle inhalation.
