Product Functional Category and Applications

1. It is used for emulsifying solubilizers of daily chemical products, and is used in the production and manufacture of various types of transparent water-based washing, cosmetics and daily necessities.

2. It plays the roles of thickening, hardening and slow-release in the preparation of pharmaceutical excipients, so it is used as thickening agent, hardening agent and slow-release agent, and can be used in the preparation of semi-solid and solid preparations, such as ointment, suppository, pills, tablets and so on.

3. Hydrogenated castor oil is used as a lubricant for tablets, such as clopidogrel bisulfate tablets, which require hydrogenated castor oil as a lubricant.

Frequently Asked Questions

Which specification items should I check for hydrogenated castor oil?

Acid value, hydroxyl value, melting point and the test methods behind them, plus confirmation that the grade is hydrogenated castor oil itself rather than a derivative. State the use when requesting the specification and COA.

Which formulations suit hydrogenated castor oil, and how do I test fit?

It is used where a waxy thickening or structuring component is needed. Fit depends on your oil phase and processing temperature, so run melt-blending and stability trials on a sample before setting dosage and grade.

What is the physical form of hydrogenated castor oil, and how should it be stored?

A waxy solid at room temperature that is melted before use. Keep bags sealed in a cool, dry place, avoid heat that softens and fuses the contents, and use opened bags promptly with the batch number recorded.

Can I get a hydrogenated castor oil sample for a melt trial?

Yes. State the formulation type, the grade and the sample size; the waxy solid is decanted from bag stock. MOQ is counted in bags, lead time follows grade stock, and the bulk order is confirmed after your trial.

Which documents support a bulk hydrogenated castor oil order, and do you export?

Shipments carry the COA, SDS and specification sheet. Export paperwork is prepared to the destination country, so name the delivery region in your enquiry and the document list is returned with the quote.
