How we scored it
Coconut fatty acid (natural) amide-bonded to hydrolyzed silk protein (natural); potassium salt (natural counter-ion) = 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
Coconut fatty acid chloride is condensed with hydrolyzed silk protein and neutralised as the potassium salt. Both acyl and protein components are natural; no petrochemical fragment is introduced.
In plain English
A gentle, protein-based cleansing ingredient made by combining coconut fatty acids with hydrolyzed silk protein. Helps cleanse while conditioning hair and skin.
CosIng definition: Potassium Cocoyl Hydrolyzed Silk is the potassium salt of the condensation product of coconut acid chloride and Hydrolyzed Silk
