Polyethylene Glycol (PEG) Hydrogenated Castor Oils | Nonionic surfactant, solubilizer, emulsifier
Cresol RH 40 and Cresol RH 50 are high-purity, non-ionic surfactants derived from hydrogenated castor oil ethoxylated with 40 or 50 moles of ethylene oxide, respectively. These materials are widely used as solubilizers, emulsifiers, and dispersing agents in pharmaceutical, cosmetic, and industrial formulations.
Manufactured with precision and consistency, our Cresol RH series offers exceptional clarity, stability, and safety, making it ideal for sensitive formulations.
