Emulphor丨CAS 9004-98-2

Emulphor (polyoxyethylene castor oil derivatives) is a versatile nonionic surfactant and solubilizer widely applied across the pharmaceutical, cosmetic, food, and industrial sectors. In pharmaceuticals, it is frequently used as a solubilizing and emulsifying agent for poorly water-soluble drugs, enhancing their bioavailability and stability in oral, topical, and injectable formulations. It plays a crucial role in producing stable oil-in-water emulsions and microemulsions, supporting the formulation of creams, lotions, and parenteral solutions. In cosmetics and personal care, Emulphor is a preferred emulsifier and dispersant in creams, shampoos, bath oils, and skin-care products, helping blend hydrophobic ingredients such as essential oils, fragrances, and vitamins into aqueous bases. In food technology, it serves as an emulsifier in flavor oils and beverage emulsions, ensuring uniform distribution of oil-based flavoring agents. Industrially, Emulphor is employed in agrochemical formulations, textile processing, metalworking fluids, and polymer emulsions due to its excellent wetting, dispersing, and solubilizing capabilities. Its compatibility with other surfactants and broad pH stability range make it a flexible choice in systems requiring consistent and reproducible performance.

The main benefits of Emulphor lie in its superior solubilization efficiency, mildness, and formulation versatility. It effectively increases the solubility of lipophilic compounds in aqueous media, thereby enhancing the delivery and stability of active ingredients in complex formulations. Its nonionic nature contributes to excellent compatibility with a wide range of ionic and nonionic compounds, minimizing formulation challenges and enabling easy incorporation into diverse systems. Emulphor demonstrates outstanding emulsification and dispersion properties even at low concentrations, which helps reduce overall formulation cost while maintaining performance. It is non-toxic, non-irritating, and biodegradable, making it suitable for sensitive applications such as pharmaceuticals, cosmetics, and food products where safety and environmental compliance are priorities. Moreover, Emulphor contributes to improved product aesthetics and texture, enhancing consumer appeal by promoting smooth, homogeneous, and stable formulations that resist phase separation or precipitation over time. Its strong thermal and chemical stability further ensures reliable performance across a wide temperature and pH range.
