Peg-40 Hydrogenated Castor Oil


Peg-40 hydrogenated castor oil is derived from castor beans, the seeds of the castor plant. Castor oil has been used in various industries for centuries for its excellent emollient and lubricating properties. The hydrogenation process converts the fatty acids in castor oil into emulsifiers and surfactants called Peg-40 Hydrogenated Castor Oil.  Aogubio ensures that this ingredient is produced using high-quality castor beans to maintain its effectiveness.


Peg-40 hydrogenated castor oil is commonly used as an emulsifier, solubilizer, and surfactant in cosmetic formulations. Its molecular weight is approximately 500-800 g/mol. The ingredient usually comes as a pale yellow liquid with minimal odor.  Aogubio offers Peg-40 hydrogenated castor oil in various packaging sizes, from vials to bulk, to meet the different needs of customers.
