How we scored it
Undecylenic acid (castor-oil pyrolysis) amide-bonded to hydrolyzed collagen; chloride leaves as HCl; K salt. All 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
Undecylenic acid, made by pyrolysis of castor oil's ricinoleic acid, is coupled to hydrolyzed collagen and neutralised with potassium. No petrochemical route is commercially used.
In plain English
A cleansing ingredient made by combining a castor-oil-derived fatty acid with broken-down collagen protein, as a potassium salt. Used in hair and skin products to clean and condition.
CosIng definition: Potassium salt of the condensation product of undecylenic acidchloride and hydrolyzed collagen
