Description

Ricinoleic Acid n-Hexadecyl Ester is a high-purity fatty acid ester derived from castor oil, specifically the esterification product of ricinoleic acid and cetyl alcohol. This compound is valued for its excellent emollient, lubricating, and surfactant properties, making it a versatile intermediate and functional additive. It is primarily sought by formulators in the personal care, cosmetics, and specialty lubricants industries for creating high-performance products with enhanced texture and stability.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, lipsticks, and sunscreens.
• Lubricants & Greases: Serves as a bio-based lubricant additive and synthetic ester base stock for specialty industrial and metalworking fluids.
• Plasticizers & Polymer Additives: Used as a secondary plasticizer and processing aid to improve flexibility and workability in polymer systems.
• Surfactants & Emulsifiers: Functions as a non-ionic surfactant intermediate for the synthesis of specialized emulsifiers.
• Textile & Leather Processing: Employed as a softening and lubricating agent in fiber treatments and leather finishing.
• Chemical Synthesis: Utilized as a key building block or intermediate in organic synthesis for pharmaceuticals and fine chemicals.
