How we scored it

Stearoyl C18H35O 267 natural (oleochemical) + SO4 96 natural (mineral, from ethosulfate); petrochemical C7H18N2 130 (DMAPA-derived linker/methyls) + C2H5 29 (ethyl groups) -> 364/523 = 0.70
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

Made by condensing natural stearic acid (from vegetable or tallow fat) with petrochemical dimethylaminopropylamine, then quaternising with a synthetic ethylating/ethosulfate agent. The fatty chain and sulfate group are natural; the amine linker is petrochemical.

In plain English

A conditioning agent combining natural stearic acid (from vegetable or animal fat) with a synthetic amine linker and an ethyl sulfate salt. Used in hair conditioners to reduce static and improve softness and combability.
