What is Ethoxylated hydrogenated castor oil?
Ethoxylated hydrogenated castor oil (CAS 61788-85-0) is a nonionic surfactant derived from hydrogenated castor oil; grades HCO-50 or HCO-60 reflect ethylene oxide chain length.
Where is Ethoxylated hydrogenated castor oil used?
- Personal care: solubilizer of fragrance oils, essential oils and lipophilic actives in aqueous systems
- Home care and industrial cleaning: stabilizer of oil-in-water emulsions in hard surface cleaners and degreasers
- Textile processing: fiber lubricant carrier and dye dispersant
- Agrochemicals: emulsifier for crop protection concentrates
- It functions as an emulsifier, solubilizer and dispersant in formulated products.
Good to know: Standard commercial grades differ by degree of ethoxylation, with HCO-40, HCO-50 and HCO-60 the most traded specifications; the choice sets the HLB value required for a system.
Commercial specifications
- Pourable liquid when warmed
- Cosmetic-grade material conforming to established purity benchmarks
