Excipients for Oral and Topical Applications
Polyoxyl 35 Castor Oil is a polyethylene glycol derivative of hydrogenated castor oil where the average PEG chain length is 35. PEG-35 hydrogenated castor oil is a nonionic surfactant used as an emulsifying and solubilising agent in pharmaceutical preparations and cosmetics.
Product Description
Pharmacopoeia specification compliance: USP/EP/ChP
Storage: In an airtight container, protected from light.
Properties and Benefits
l The raw material is refined castor oil, with light color and high purity.
l Using precision polymerization technology to obtain narrow molecular distribution and good batch-to-batch repeatability.
l Low acid value, free fatty acid and peroxide value to ensure good stability of preparations.
Applications
l Nonionic surfactant, HLB value is about 12-14.
l It can be used effectively in self-emulsifying drug delivery systems (SEDDS) and enhance solubility and bioavailability of APIs, especially suitable for solution dosage forms containing volatile oils, fat-soluble and other hydrophobic drugs.
