SODIUM STEAROYL GLUTAMATE ●
TL;DR. It functions mainly as a mild anionic emulsifier and co-emulsifier, helping oil and water phases form stable creams, lotions, and sunscreen emulsions. It can also add a light conditioned feel on skin and hair.
What does SODIUM STEAROYL GLUTAMATE do in a cosmetic formula?
It functions mainly as a mild anionic emulsifier and co-emulsifier, helping oil and water phases form stable creams, lotions, and sunscreen emulsions. It can also add a light conditioned feel on skin and hair.
Is SODIUM STEAROYL GLUTAMATE clean?
From a clean-beauty perspective, this ingredient is generally well regarded because it is mild, non-ethoxylated, and not a common sensitizer. It has little restricted-list friction when made with well-controlled raw materials.
Is SODIUM STEAROYL GLUTAMATE sustainable?
This material is typically made from a vegetable fatty acid fraction and an amino acid source, with possible palm or palm-kernel sourcing depending on the supply chain. It is expected to be readily biodegradable and is not associated with environmental persistence concerns.
Is SODIUM STEAROYL GLUTAMATE COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when sourced and processed according to the standard. Its profile fits Green Chemistry reasonably well because it is biodegradable, can use renewable feedstocks, and does not require ethoxylation.
How does SODIUM STEAROYL GLUTAMATE work chemically?
The molecule is a sodium salt of an amino-acid-derived amphiphile, with a long C18 lipid tail and polar carboxylate groups that support oil-in-water emulsification. Typical use is about 0.1% to 1.5% in emulsions, often with fatty alcohols, gums, or nonionic emulsifiers, and it performs best around mildly acidic to neutral pH.
