How we scored it
Hydrogenated tallow acyl (mainly stearoyl and palmitoyl, animal fat) + glutamate (fermentation) + 2 Na (mineral); nothing petrochemical remains: 1.00.
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
Dominant route: hydrogenated tallow fatty acid chloride acylates fermentation-derived L-glutamic acid, then the product is neutralised with sodium hydroxide. A vegetable-oil acyl chain would give the same value.
In plain English
A cleansing and conditioning amino-acid surfactant used in washes and hair products. It joins fatty acids from hydrogenated animal fat (tallow) to glutamic acid, an amino acid made by fermentation, as the disodium salt.
CosIng definition: Glutamic acid, N-tallow-acyl derivs., disodium salts
