Sodium lauroyl sarcosinate
Sodium lauroyl sarcosinate is a synthetic or plant-derived surfactant (cleansing agent) that also works as an emulsifier. It is most often used in face and body cleansers and shampoos but is sometimes also used in leave-on products.
This versatile ingredient works well with various glycols, silicones, solvents, and phosphate esters.
Safety assessments have confirmed this ingredient is non-irritating and non-sensitising when applied to human skin in amounts (up to 15% in rinse-off and 5% in leave-on products) that are approved for use in cosmetics.
