Description

10-Undecenoic Acid Octyl Ester is a high-purity organic ester derived from 10-undecenoic acid, a key intermediate from castor oil. This compound matters as a versatile, non-volatile liquid intermediate prized for its excellent solvency, stability, and hydrophobic properties. It is primarily needed by manufacturers in the fragrance, cosmetic, and specialty polymer industries as a precursor or modifying agent.

Application

• Fragrance and Flavor Industry: Used as a solvent, fixative, or as a starting material for the synthesis of musk-like aroma chemicals and other specialty fragrance ingredients.
• Cosmetics and Personal Care: Acts as an emollient, skin-conditioning agent, or carrier oil in formulations for lotions, creams, and lipsticks due to its smooth texture and low volatility.
• Polymer and Resin Modification: Serves as a plasticizer or comonomer in the production of specialty polymers, coatings, and adhesives to enhance flexibility and hydrophobic character.
• Lubricant and Grease Formulation: Employed as a synthetic base oil or additive in high-performance lubricants and greases requiring thermal stability and low pour point.
• Chemical Synthesis: A valuable building block in organic synthesis for producing surfactants, corrosion inhibitors, and other functional derivatives.
