Mostly natural · ISO 16128

Is Stearamidopropyl Cetearyl Dimonium Tosylate natural?

Mostly. Stearoyl and cetearyl chains come from vegetable fatty acids and alcohols and the sulfonate is mineral; DMAPA (amide N, propylene, NMe2) and the tolyl ring of tosylate are petrochemical.

How we scored it

Natural: stearoyl C18H35O 267 + cetearyl C17H35 239 (avg) + tosylate SO3 80 (mineral sulfonate) = 587 Da; petrochemical: DMAPA part C5H13N2 101 + tolyl C7H7 91; total 779; 587/779 = 0.75.
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

Likely route: stearic acid is condensed with DMAPA and quaternised with a cetearyl tosylate made from C16/C18 vegetable alcohol and tosyl chloride. Supplier note: synthetic fatty chains are possible but uncommon.

In plain English

A conditioning ingredient for hair-care products: two fatty chains from vegetable oils attached to a positively charged nitrogen head, with tosylate as the counter-ion. It coats hair, helps detangling and reduces static. The head group and tosylate are made from petrochemicals.

CosIng definition: 1-Propanaminium, N-(mixed octadecyl and hexadecyl)-N,N-dimethyl-3-(1-oxooctadecyl)amino-, 4-methylbenzenesulfonate
