How we scored it

Coco fatty acyl (coconut, natural) + hydrolyzed silk protein (animal, natural) + Na — all natural building blocks → 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

Silk protein is hydrolysed to peptides, then acylated with coconut fatty acid and neutralised with sodium hydroxide. No petrochemical route is used.

In plain English

A mild cleansing and conditioning ingredient made from coconut oil fatty acids combined with proteins from silk. Used in shampoos and skin washes for a soft, conditioned feel.
