Chemical Properties Of Cremophor EL Cas 61791-12-6

Cremophor EL is a class of nonionic surfactants produced by the ethoxylation of castor oil with ethylene oxide. It exhibits excellent surface tension-reducing properties, with its aqueous solution forming stable micelles even at low concentrations. Chemical Stability: Stable under neutral and weakly acidic conditions; prone to hydrolysis in strong alkalis. Relatively stable toward oxidizing agents, resisting oxidation degradation. Heat-resistant (typical thermal decomposition temperature >200°C); viscosity decreases upon heating without structural alteration.

Product Application Of Cremophor EL Cas 61791-12-6

  1.  As a pharmaceutical excipient, castor oil polyoxyethylene ether is commonly used as a solubilizer, emulsifier, dispersant, and transdermal enhancer in injectables, oral formulations, and topical preparations.
  2.  Castor Oil Ethoxylates, with their low irritancy and excellent compatibility, are widely used in skincare, cosmetics, and cleansing products. They serve as emulsifiers in creams and lotions, solubilizers for fragrances and essential oils, and moisturizing agents.
  3.  As a food additive, ethoxylated castor oil primarily improves food texture and stability. It functions as an emulsifier in dairy products and baked goods, a dispersant in beverages, and a defoaming agent.
  4.  Polyoxyethylene castor oil serves as a textile auxiliary in the textile industry, used for emulsion dyeing and softening treatments of fabrics.
  5.  In the coatings and ink industry, it functions as an emulsifier and dispersant in water-based paints and inks.
  6.  In metal cutting fluids, ethoxylated castor oil serves as an emulsifier to form stable water-based cutting fluids, providing lubrication, cooling, and rust prevention.
  7.  It is used in the preparation of pesticide emulsifiable concentrates and suspension concentrates to enhance the dispersibility and penetration of active pesticide ingredients.
