How we scored it

Tetradecanol 214.4 (natural) + 2.5EO 110.1 (petrochemical) + SO3 80.1 (mineral) + DEA-H+ C4H12NO2 106.1 (petrochemical, ethylene-oxide/ammonia amine); natural 294.5/total 510.7 = 0.58
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

Myristyl alcohol from coconut or palm kernel oil is ethoxylated, sulfated, and neutralised with diethanolamine, a petrochemical amine.

In plain English

A cleansing and foaming surfactant made from myristyl alcohol (a coconut or palm-derived fatty alcohol) reacted with ethylene oxide and sulfate, then neutralised with diethanolamine. Used in shampoos and washes.
