Overview of Polyoxyethylene Castor Oil
Polyoxyethylene castor oil is a non-ionic surfactant with both hydrophilic and hydrophobic properties. It is a product obtained by the addition reaction of castor oil and ethylene oxide, followed by polymerization. Polyoxyethylene Castor Oil has a variety of excellent properties, such as good surface activity, emulsification, solubilization, stabilization, biocompatibility and chemical stability. Therefore, it is widely used in cosmetics, food, medicine, chemical industry and other fields.

FAQs of Polyoxyethylene Castor Oil
What is Polyoxyethylene castor oil used for?
This compound is widely used in pharmaceutical formulations as a solubilizing agent and emulsifier. It is particularly noted for its role in enhancing the bioavailability of poorly soluble drugs. Additionally, it finds use in cosmetic products and industrial applications where emulsification and wetting properties are required.
Is Polyoxyethylene castor oil safe for pharmaceutical applications?
Yes, Polyoxyethylene castor oil has been evaluated and approved for use in pharmaceutical preparations. However, like all excipients, it should be used within established guidelines. Some individuals may experience hypersensitivity reactions, so it's important to conduct proper testing before final product release.
How does the degree of ethoxylation affect Polyoxyethylene castor oil?
The degree of ethoxylation (the number of ethylene oxide units added to the castor oil molecule) affects the hydrophilicity of the product. Higher degrees of ethoxylation result in greater water solubility and increased effectiveness as an emulsifier and solubilizer. CAS 61791-12-6 indicates a high level of ethoxylation, making it very effective for these purposes.
Can Polyoxyethylene castor oil be used in natural or organic products?
While derived from natural castor oil, the process of ethoxylation involves chemical synthesis, which may not meet strict definitions of "natural" or "organic". Certification bodies have different criteria; therefore, whether it qualifies for use in natural or organic products depends on the certification standards being followed.
What is the shelf life of Polyoxyethylene castor oil?
Under proper storage conditions – cool, dry place away from direct sunlight and heat sources – the shelf life of Polyoxyethylene castor oil can typically extend up to two years. Always check the expiration date provided by the supplier and adhere to recommended storage practices to maintain product integrity.
