Is Coceth-7 natural?

Mostly not. Coconut-derived fatty alcohol blend provides the natural fragment; the 7-unit ethylene oxide chain is petrochemical.

How we scored it

Coco fatty alcohol avg ~200 Da (oleochemical, C12-C14 dominant blend) + 7xEO 44.05=308.4 Da (petrochemical) -> total 508.4 Da; 200/508.4 = 0.39.
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 ethoxylating coconut-oil-derived fatty alcohol with petroleum-derived ethylene oxide. No significant petrochemical alternative exists for the coco alcohol fraction itself.

In plain English

A cleansing and emulsifying ingredient made from coconut-derived fatty alcohols reacted with 7 units of ethylene oxide, a petroleum-derived building block. Helps blend oil and water in cleansers and creams.

CosIng definition: Alcohols, coco, ethoxylated (7 mol EO average molar ratio)
