How we scored it
Formula checks exactly: oleic acid (282 Da) + glycine (75 Da) - water (18) = 339.5 Da. Acid-chloride activation leaves no residue; both 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
Made by acylating glycine, a fermentation-derived amino acid, with oleic acid activated as its acid chloride. The chlorine leaves as HCl and is not part of the final molecule.
In plain English
A gentle cleansing ingredient made by combining a vegetable-oil fatty acid with glycine, a simple amino acid. Used in cleansers for mild foaming and skin conditioning.
CosIng definition: Oleoyl Glycine is the acylation product of glycine with oleic acid chloride. It conforms to the formula
Structure
