How we scored it
Stearoyl (vegetable-oil fatty acyl, natural) amide-bonded to glutamic acid (fermentation amino acid, natural), potassium salt (mineral, natural). All fragments natural. 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Vegetable-oil-derived stearic acid is condensed with fermentation-derived glutamic acid and neutralised with potassium. All three building blocks are natural-origin by convention.
In plain English
A skin- and hair-conditioning ingredient made by combining a fatty acid from vegetable oil with glutamic acid, an amino acid, then adding potassium. Helps soften and smooth skin and hair.
CosIng definition: Potassium salt of stearoyl glutamic acid
