Is PEG-100 Stearate Natural?

Q: Is PEG-100 Stearate natural?

PEG-100 Stearate has a Natural Origin Index (NOI) of 0.00 (scale 0–1) per ISO 16128. PEG-100 Stearate is synthesized from polyethylene glycol and stearic acid, both of which are primarily derived from petrochemical feedstocks, resulting in a Natural Origin Index… An NOI of 0.00 means 0% of its molecular mass is traceable to a natural, renewable source.

FunctionsEmulsifierSurfactant
Primary FeedstockThe primary feedstocks for PEG-100 Stearate are polyethylene glycol (PEG) and stearic acid. Polyethylene glycol is typically produced via the polymerization of ethylene oxide, which is derived from ethylene, a petrochemical. Stearic acid is commonly sourced from the hydrolysis of animal fats and vegetable oils, but for cosmetic-grade ingredients, it is often synthesized from petrochemical sources or derived from palm oil, which can have sustainability concerns.
