How we scored it
Undecylenic acid (castor-oil pyrolysis) amide-bonded to hydrolyzed soy protein; 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 from castor oil pyrolysis is coupled to hydrolyzed soy protein and neutralised with potassium. No petrochemical route is commercially used.
In plain English
A conditioning ingredient made by combining a castor-oil-derived fatty acid with broken-down soy protein, as a potassium salt. Used in hair and skin products and to help stabilise emulsions.
CosIng definition: Potassium salt of the condensation product of undecylenic acid chloride and hydrolyzed soy protein
