Description

Ricinoleyl Alcohol CAS NO 540-11-4 is a long-chain fatty alcohol derived from castor oil, specifically the hydrogenation of ricinoleic acid. This specialty intermediate is valued for its unique bifunctional structure, containing both a hydroxyl group and a long aliphatic chain, which imparts excellent emolliency, lubricity, and reactivity. It is a critical raw material for manufacturers in the personal care, lubricants, and polymer industries seeking to develop high-performance, bio-based formulations.

Application

• Personal Care & Cosmetics: Acts as a non-greasy emollient and viscosity modifier in creams, lotions, and lipsticks.
• Lubricants & Greases: Serves as a base fluid or additive in bio-based lubricants, offering good thermal stability and low pour point.
• Polymer & Resin Synthesis: Used as a monomer or chain extender in the production of polyesters, polyurethanes, and alkyd resins.
• Plasticizers: Functions as a secondary plasticizer and stabilizer in PVC and other polymer systems.
• Surfactants & Esters: A key intermediate for synthesizing nonionic surfactants, emulsifiers, and specialty esters for various industrial applications.
• Textile & Leather Processing: Employed as a softening agent and lubricant in fiber processing and leather finishing.
