How we scored it

Methyl glucoside core C7H14O6 194 Da (natural) + 10 mol ethylene oxide ×44 Da = 440 Da (petrochemical) → 194/634 = 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

Made by ethoxylating methyl glucoside (from corn glucose and methanol) with about 10 moles of petrochemical ethylene oxide. No natural route exists for the ethoxylate chain itself.

In plain English

A moisturising, emulsifying ingredient made from corn sugar reacted with a synthetic ethylene-oxide chain. It helps blend oil and water and holds moisture in skin and hair products.
