Where it comes from
Soybean sterols are reacted with 25 moles of ethylene oxide for a highly water-dispersible emulsifier. The sterol is plant-derived; the long ethoxylate chain is petrochemical.
In plain English
Plant sterols from soybeans reacted with a larger amount of ethylene oxide (a petrochemical) to make them water-compatible. Used as an emulsifier that helps blend oil and water phases in creams and lotions.
