About PEG 40 HCO
Hydrogenating castor oil, then ethoxylating ethylene oxide, the typical yield recovery is around 85–90%
Hydrogenating castor oil, then ethoxylating ethylene oxide, the typical yield recovery is around 85–90% Raw Material: Castor oil, Hydrogen (for hydrogenation),Catalyst (e.g., nickel-based), Ethylene oxide (EO) Overall Formula: Castor Oil + H₂ → Hydrogenated Castor Oil → + 40 EO → PEG-40 Hydrogenated Castor Oil
