Description

4-Hydroxybutyl Oleate is a high-purity oleic acid ester derivative, valued for its excellent emollient properties and chemical versatility. This compound serves as a key intermediate and functional additive, offering a unique combination of lipophilic character and a reactive hydroxyl group. It is primarily utilized in the formulation of advanced lubricants, high-performance plasticizers, and sophisticated personal care products where skin compatibility and stability are critical.

Application

• Lubricant & Grease Additive: Functions as a friction modifier and viscosity index improver in synthetic and semi-synthetic lubricants.
• Polymer & Plasticizer Intermediate: Used in the synthesis of specialty polymers and as a co-monomer or secondary plasticizer to enhance flexibility and low-temperature performance.
• Personal Care & Cosmetics: Acts as a non-greasy, spreading emollient and solvent in creams, lotions, and makeup formulations.
• Metalworking Fluids: Incorporated as a lubricity agent and corrosion inhibitor in cutting and grinding fluids.
• Textile & Leather Processing: Serves as a softening agent and lubricant for fibers and leather finishes.
• Industrial Coatings & Inks: Used as a flow modifier and plasticizing agent to improve film formation and adhesion.
