Where it comes from
Oleochemical stearic acid esterified with polyethylene glycol made from petrochemical ethylene oxide. The stearic acid portion is renewable; the PEG-10 chain has no natural equivalent.
In plain English
An emulsifier used to blend oil and water phases in creams. A natural fatty acid is combined with a longer chain of petroleum-derived ethylene oxide, making it mostly synthetic by weight.
