Description
Kolliphor ELP, a purified grade of Kolliphor EL was specially developed for sensitive active ingredients, as the higher purity was found to improve their stability. Like Kolliphore EL, Kolliphor ELP is a nonionic solubiliser made by reacting castor oil with ethelene oxide in a molar ration of 1:35. This is followed by a purification process
Unlike Kolliphor EL, Kolliphor ELP is a white to yellowish paste or cloudy liquid. It has to fulfill more exacting requirements with regard to water content, Potassium ions and free fatty acids, particularly ribonucleic, olefin and Palmitic acids.
