How we scored it

Dodecyl C12H25 169.33 Da (natural) + Cl 35.45 Da (natural mineral) = 204.78; benzyl C7H7 91.13 Da + 2x hydroxyethyl 90.12 Da + N 14.01 Da (petrochemical) = 195.26; 204.78/400.0 = 0.51
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 quaternizing N,N-bis(2-hydroxyethyl)dodecylamine (dodecyl from coconut oil, hydroxyethyl from ethylene oxide) with benzyl chloride from toluene. Supplier note on oleochemical dodecyl source.

In plain English

A synthetic antimicrobial ingredient made from a coconut-derived fatty chain and a benzyl group, used to control microbial growth in formulas.
