Description

Behenic Anhydride is a high-purity, long-chain fatty acid derivative essential for introducing the behenoyl moiety into various chemical structures. This compound is valued for its role in synthesizing specialized esters, amides, and polymers that require the unique properties of a C22 saturated chain. It is a critical intermediate for manufacturers in the cosmetics, personal care, lubricant, and plasticizer industries, where it imparts enhanced stability, texture, and performance characteristics to final formulations.

Application

• Cosmetic & Personal Care Ingredients: Key intermediate for synthesizing emulsifiers, emollients, and texture enhancers in creams, lotions, and makeup.
• Lubricant & Grease Additives: Used to produce high-melting-point esters and derivatives that improve thermal stability and lubricity.
• Polymer Modification: Serves as a monomer or modifier in the production of specialty polyamides, polyesters, and coatings to enhance flexibility and water resistance.
• Plasticizer Synthesis: A precursor for creating polymeric plasticizers that offer low volatility and excellent compatibility with PVC and other resins.
• Pharmaceutical Intermediates: Employed in the synthesis of prodrugs and active pharmaceutical ingredients (APIs) requiring long-chain fatty acid functionalization.
• Surfactant & Detergent Manufacturing: Used to create behenate-based surfactants for specialized cleaning and industrial applications.

Quality Control

Our Behenic Anhydride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatography and titration methods, to ensure high purity and consistent performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, acid value, and moisture content. Our quality commitment supports applications requiring reliable and traceable raw materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
