Polyoxyl（35）Castor Oil (For Injection）

Excipients for Injection

Polyoxyl（35）Castor Oil s a solubilizer, emulsifier and primary surfactant used in a multitude of pharmaceutical formulations, with the primary indication for sensitive APIs and parenteral use and Polyoxyl（35）Castor Oil is a white to yellowish paste or cloudy liquid. It is a non-ionic solubilizer made by reacting castor oil with ethylene oxide in a molar ratio of 1:35. This is followed by a purification process and forms clear solutions in water and also dissolves in a wide range of organic solvents, such as ethanol, n-propanol, isopropanol, ethyl acetate, chloroform, carbon tetrachloride, trichloroethylene, toluene and xylene.
