Is Methyl Glucose Sesquioleate natural?

Mostly. Methyl glucoside (glucose core natural, methanol-derived methyl group petrochemical) esterified with 1.5 mol natural oleic acid; small methyl fraction lowers score from 1.0.

How we scored it

Methyl glucoside (194 Da = 163 Da glucose + 31 Da methanol-derived OMe) + 1.5 oleic acid (282 Da ea, natural) − 1.5 H2O; natural 560/total 591 ≈ 0.95.
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 reacting corn-derived glucose with methanol to form methyl glucoside, then esterifying with plant-derived oleic acid. The methyl group is the only petrochemical fragment; no alternative natural methylation route is used commercially.

In plain English

An emollient emulsifier made by combining corn sugar (glucose) with plant-derived oleic acid. Helps blend oil and water and softens skin in creams and lotions.
