Mostly petroleum · ISO 16128

Is Coceth-10 natural?

Mostly not. Longer ethylene-oxide chain makes this mostly petrochemical by mass despite the natural fatty-alcohol core.

INCI nameCoceth-10

FunctionEmulsifying Surfactant · Cleansing Surfactant
FeedstockCoconut-derived fatty alcohol ethoxylated with 10 mol petrochemical…

How we scored it

Coco alcohol (~200 Da, natural) + 10x44 Da EO (petrochemical) = 641 Da; 200/641=0.31.
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

Coconut-derived fatty alcohol ethoxylated with 10 mol petrochemical ethylene oxide. No alternative route.

In plain English

A surfactant made from coconut-derived fatty alcohol reacted with a longer chain of ethylene oxide, used to clean and emulsify oils in washes and cleansers.

CosIng definition: Alcohols, coco, ethoxylated (10 mol EO average molar ratio)
