General description

Castor Oil, Ethoxylated is a nonionic solubilizer and emulsifier made by reacting castor oil with ethylene oxide. It is a pale yellow oily liquid that is clear at temperatures above 26°C. It has a faint but characteristic odour.
Castor Oil, Ethoxylated is polyethylene oxide surfactant and is viscous in nature. It has a hydrophobic-lipophilic balance value in the range of 12-14.

Application

Castor Oil, Ethoxylated has been used as a detergent to improve the solubility of dye and to increase the transmembrane permeation. It has been used as a vehicle for drug/stimulant delivery in cells.

Biochem/physiol Actions

Castor Oil, Ethoxylated is used in lipid-based formulations for drugs and solubilization of cosmetics. Castor Oil, Ethoxylated is suitable for the production of semi-solid and liquid formulations of water-insoluble actives and other hydrophobic compounds. Due to its emulsification functionality, it finds application in biological membrane- based drug transport studies.

Other Notes

A derivative of castor oil and ethylene oxide.
