How we scored it

Coco fatty acid-amidoamine (natural, would be 1) + synthetic propanediamine + epoxy-terminated siloxane + lactate salt. Silicone content forces 0.00 by convention.
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

Manufactured by reacting coconut-derived fatty acids with a synthetic propanediamine, then capping with an epoxy-terminated silicone and neutralising with lactic acid. The silicone segment invokes the site's blanket 0.0 convention.

In plain English

A silicone-based hair conditioning ingredient made by combining coconut fatty acids, a synthetic amine, and silicone. Despite the coconut-derived portion, its silicone content means it is classed as synthetic.

CosIng definition: Fatty acids, coco, reaction products with N1,N1-dimethyl-1,3-propanediamine and 3-(2-oxiranylmethoxy) propyl group-terminated [(phenylsilylidyne)tris(oxy)]tris[di-methyl siloxanes], lactates (salts)
