Sodium Lauryl Sulfoacotate ●
TL;DR. This ingredient is a mild anionic surfactant used to create foam, lift oil and soil, and improve cleansing in shampoos, facial cleansers, body washes, bath products, and syndet bars.
What does Sodium Lauryl Sulfoacotate do in a cosmetic formula?
This ingredient is a mild anionic surfactant used to create foam, lift oil and soil, and improve cleansing in shampoos, facial cleansers, body washes, bath products, and syndet bars.
Is Sodium Lauryl Sulfoacotate clean?
Clean-beauty frameworks generally view it as acceptable, with a better skin-comfort profile than many smaller anionic cleansers. It can still feel drying or irritating at high use levels, especially in powders or concentrated rinse-off formats.
Is Sodium Lauryl Sulfoacotate sustainable?
This material is commonly made from fatty alcohol feedstocks that may come from coconut or palm kernel sources, so traceable sourcing matters. It is considered readily biodegradable and does not raise the same persistence concerns as silicone or fluorinated materials.
Is Sodium Lauryl Sulfoacotate COSMOS-approved?
It is generally permitted under COSMOS-natural when sourced and processed according to the standard, mainly for cleansing applications. Its Green Chemistry fit is good on biodegradability and potential renewable carbon, with some compromise from synthetic conversion steps and palm-linked supply chains.
How does Sodium Lauryl Sulfoacotate work chemically?
The molecule is a sodium salt with a C12 lipophilic tail and an anionic sulfonated acetate head group, which supports micelle formation, detergency, and dense foam. Typical use ranges are about 3 to 15 percent active in liquid rinse-off cleansers and higher in solid or powdered bath formats, with best stability around mildly acidic to neutral pH.
