Sodium Lauryl Sulfoacetate ●
TL;DR. This ingredient is a high-foaming anionic surfactant used to cleanse, disperse oils, and build dense lather in shampoos, facial cleansers, bubble baths, and solid cleansing formats.
What does Sodium Lauryl Sulfoacetate do in a cosmetic formula?
This ingredient is a high-foaming anionic surfactant used to cleanse, disperse oils, and build dense lather in shampoos, facial cleansers, bubble baths, and solid cleansing formats.
Is Sodium Lauryl Sulfoacetate clean?
It has a favorable clean-beauty profile because it is readily biodegradable, sulfate-free, and typically milder than many high-foam anionic cleansers. The main practical caveat is that fine powder can irritate the nose and throat during handling before it is incorporated into a formula.
Is Sodium Lauryl Sulfoacetate sustainable?
This material is commonly made from fatty alcohols sourced from coconut or palm, so responsible palm documentation can matter. It is considered readily biodegradable and does not raise the persistence concerns associated with silicone or fluorinated materials.
Is Sodium Lauryl Sulfoacetate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when the feedstocks and manufacturing route meet the standard’s surfactant rules. Its Green Chemistry fit is solid because it can use renewable fatty feedstocks and has good biodegradability, though it still relies on chemical conversion rather than minimal processing.
How does Sodium Lauryl Sulfoacetate work chemically?
The molecule has a C12 fatty chain linked to an esterified, sulfonated head group, giving it strong anionic surface activity and high foam. It is commonly used around 1 to 20% depending on format, performs well in mildly acidic to neutral pH systems, and is often blended with amphoteric or nonionic surfactants to improve mildness and foam feel.
