PEG-40 Hydrogenated Castor Oil is a nonionic, water-dispersible surfactant and solubilizing excipient produced by ethoxylation of hydrogenated castor oil. The “PEG-40” designation refers to an average of approximately 40 moles of ethylene oxide incorporated into the hydrogenated castor oil derivative.
It is widely used as a solubilizer, emulsifier, surfactant, dispersing agent and formulation aid in pharmaceutical, nutraceutical, cosmetic and personal-care formulations.
Swapnroop Pharma manufactures and supplies PEG-40 Hydrogenated Castor Oil in India for qualified formulation and industrial applications. The material can be supplied according to the required grade, physicochemical characteristics, purity requirements and applicable regulatory standards.
PEG-40 Hydrogenated Castor Oil is a useful nonionic surfactant for formulations where improved solubilization, dispersion or emulsification of poorly water-soluble ingredients is required.
Its functions may include:
PEG-40 Hydrogenated Castor Oil can be used in selected:
It is particularly useful in formulation development involving poorly water-soluble ingredients, where a nonionic surfactant can help improve dispersion and apparent solubility.
PEG-40 Hydrogenated Castor Oil is a complex ethoxylated mixture, rather than a single low-molecular-weight compound. It contains polyethylene glycol chains associated with hydrogenated castor oil-derived fatty components.
Because it is a mixture, its molecular formula and molecular weight are not represented by one fixed value. Product characteristics depend on the manufacturing process and grade.
It is generally supplied as a white to pale-yellow waxy solid, flakes, pellets or semi-solid material, depending on grade and temperature.
Swapnroop Pharma supplies PEG-40 Hydrogenated Castor Oil to pharmaceutical, nutraceutical, cosmetic and specialty formulation manufacturers.
Grade selection can be aligned with requirements for:
PEG-40 Hydrogenated Castor Oil should be stored in tightly closed, moisture-protective packaging in a cool, dry and well-ventilated area. Excessive heat, direct sunlight, moisture and contamination should be avoided.
Storage conditions should follow the approved product specification and SDS for the selected grade.
Depending on grade and customer requirements, documentation may include:
Swapnroop Pharma supplies PEG-40 Hydrogenated Castor Oil for qualified pharmaceutical, nutraceutical, cosmetic and specialty formulation applications in India and international markets.
