Description

Methyl Ricinoleate is the methyl ester of ricinoleic acid, a key derivative of castor oil. This specialty ester is valued for its unique combination of a polar hydroxyl group and a non-polar hydrocarbon chain, making it a versatile intermediate and functional additive. It is primarily sought by manufacturers in the cosmetics, lubricants, plastics, and specialty chemical industries for its emollient properties, biodegradability, and utility as a chemical building block.

Application

• As a key emollient and skin-conditioning agent in high-end cosmetic and personal care formulations, such as lotions, creams, and lipsticks.
• As a bio-based lubricant additive and synthetic lubricant base stock, offering excellent low-temperature performance and biodegradability.
• As a plasticizer and compatibilizer in polymer systems, including PVC and nitrocellulose, to improve flexibility and processing.
• As a chemical intermediate for the synthesis of surfactants, emulsifiers, and other ricinoleate-based derivatives.
• As a component in metalworking fluids and corrosion inhibitors due to its polar nature and film-forming characteristics.
• In the production of flavors and fragrances as a precursor or solvent.
