Is PEG-10 Sunflower Glycerides natural?

Mostly. Glyceride backbone and sunflower fatty acids are natural; the ethylene-oxide chain is petrochemical.

How we scored it

Sunflower mono/diglyceride ~480Da (avg fatty acid ~277Da) + 10 EO x44Da=440Da petrochemical; NOI=480/920=0.52.
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 mono- and diglycerides of sunflower seed oil with about 10 moles of ethylene oxide. The glyceride portion is plant-derived; ethoxylation uses petrochemical ethylene oxide.

In plain English

An emulsifier made from sunflower oil that has been chemically modified with a petroleum-derived compound (ethylene oxide) to help oil and water mix in a formula.

CosIng definition: Glycerides, sunflower seed oil (Helianthus annuus) mono- and di-, ethoxylated (10 mol EO average molar ratio)
