Description

Dilinoleic Acid is a high-purity, unsaturated fatty acid dimer derived from linoleic acid, valued for its unique chemical structure and reactivity. This compound serves as a versatile intermediate and functional additive, offering enhanced stability and performance characteristics compared to its monomeric precursors. It is essential for manufacturers in the polymer, lubricant, and personal care industries seeking to develop advanced materials with tailored properties.

Application

• Polymer & Resin Modification: Acts as a reactive diluent, plasticizer, or cross-linking agent in alkyd resins, polyesters, and epoxy systems to improve flexibility and durability.
• Lubricant & Grease Formulation: Used as a base stock or additive to enhance thermal stability, oxidation resistance, and lubricity in synthetic lubricants and industrial greases.
• Personal Care & Cosmetics: Employed as an emollient and skin-conditioning agent in creams, lotions, and other cosmetic formulations.
• Surfactant & Emulsifier Synthesis: Serves as a key hydrophobic building block for producing non-ionic surfactants and emulsifiers.
• Corrosion Inhibitors: Utilized in the formulation of protective coatings and additives for metalworking fluids.
• Research & Chemical Synthesis: A valuable intermediate for organic synthesis and pharmaceutical research due to its reactive double bonds.
