Ethoxylated hydrogenated castor oil

Ethoxylated hydrogenated castor oil (CAS 61788-85-0 ), commonly supplied as HCO-50 or HCO-60 based on ethylene oxide chain length, is a nonionic surfactant derived from hydrogenated castor oil. It functions primarily as an emulsifier, solubilizer, and dispersant across a broad range of formulated products.

In personal care, it solubilizes fragrance oils, essential oils, and lipophilic actives into aqueous systems. This is critical for clear bath oils, micellar waters, and leave-on skin formulations where clarity and stability are essential for consumer appeal.

Home care and industrial cleaning formulators use it to stabilize oil-in-water emulsions in hard surface cleaners and degreasers. Consistent droplet dispersion directly affects cleaning performance and the overall shelf life of the chemical product.

Textile processing relies on it as a fiber lubricant carrier and dye dispersant. This application improves dye bath uniformity and reduces streaking on synthetic fabrics, ensuring a high-quality finish during the manufacturing process.

In agrochemical formulations, it acts as an emulsifier for crop protection concentrates. It enables the creation of stable emulsifiable concentrates and suspension concentrates, which are vital for effective agricultural applications in the field.

Ethoxylated hydrogenated castor oil is supplied as a waxy solid or paste at ambient temperature. It typically transitions to a pourable liquid when warmed, making it easier to handle and incorporate into various industrial manufacturing processes.

Standard commercial grades are differentiated by degree of ethoxylation, with HCO-40, HCO-50, and HCO-60 being the most traded specifications. These variations allow formulators to select the specific HLB value required for their system.

Cosmetic-grade material conforming to established purity benchmarks is available alongside technical-grade product for industrial applications. This ensures that the material meets the specific safety and performance requirements of different market sectors.
