Question 1

What does Disodium Stearoyl Glutamate do in a cosmetic formula?

Accepted Answer

This ingredient functions mainly as a mild anionic oil-in-water emulsifier and co-emulsifier. It helps stabilize creams and lotions while contributing a smooth, conditioned skin feel.

Question 2

Is Disodium Stearoyl Glutamate clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well accepted and has low irritation potential at normal cosmetic use levels. It has little restricted-list friction compared with more controversial surfactants or ethoxylated emulsifiers.

Question 3

Is Disodium Stearoyl Glutamate sustainable?

Accepted Answer

This material is commonly made from fatty acid feedstocks and an amino acid, often with plant or fermentation-based inputs. It is expected to be biodegradable, though the fatty acid source may carry palm or palm-kernel traceability considerations depending on the supplier.

Question 4

Is Disodium Stearoyl Glutamate COSMOS-approved?

Accepted Answer

It is generally permitted in COSMOS-natural and COSMOS-organic formulations when made from approved raw materials as a chemically processed agro-ingredient. Its profile fits Green Chemistry reasonably well because it can use renewable inputs, is used at low levels, and is designed for biodegradability.

Question 5

How does Disodium Stearoyl Glutamate work chemically?

Accepted Answer

The molecule is an amino-acid lipid with a long C18 hydrophobic chain and two hydrophilic carboxylate salt groups, which lets it sit at the oil-water interface and stabilize droplets. Typical use levels are about 0.1% to 1.5%, often paired with fatty alcohols, waxes, or glyceryl esters, and performance is usually best in mildly acidic to neutral emulsions where extreme pH or high electrolyte load can shift viscosity and stability.
