Description

Isooctadecenoic Acid is a monounsaturated fatty acid derivative characterized by its branched-chain structure. This unique molecular architecture provides distinct chemical and physical properties compared to its linear counterparts, making it a valuable intermediate for high-performance applications. It is particularly sought after by manufacturers in the specialty chemical, lubricant, and polymer industries seeking to enhance product stability and functionality.

Application

• As a key intermediate in the synthesis of specialty esters for high-performance lubricants and metalworking fluids.
• In the production of polymer additives, including plasticizers and stabilizers, to improve material flexibility and durability.
• For the manufacture of surfactants and emulsifiers used in industrial cleaning and formulation chemistry.
• As a building block for cosmetic and personal care ingredients, such as emollients and texture enhancers.
• In corrosion inhibitor formulations for industrial water treatment and metal protection.
• As a reactive modifier in alkyd resins and other coating systems to alter film properties.

Quality Control

Our Isooctadecenoic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, acid value, iodine value, and color are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve quality. Keep away from strong oxidizers and heat sources.
