Is Butyl Glucoside natural?

Mostly. Glucose comes from starch while butanol is made from propylene by oxo synthesis, so only the sugar part counts as natural origin.

How we scored it

Glucosyl C6H11O5 163.2 (glucose, natural) + butoxy C4H9O 73.1 (butanol, petrochemical oxo alcohol). Total 236.3; 163.2/236.3 = 0.69.
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

Dominant route: acid-catalysed glycosylation of starch-derived glucose with petrochemical n-butanol. Fermentation bio-butanol exists but is not commercially significant for this ingredient.

In plain English

A small sugar-based cleansing ingredient used in washes. It is made by joining glucose, from starch such as corn, to butanol, a petrochemical alcohol.
