Description

2-n-Hexadecylstearic Acid is a high-purity, long-chain branched fatty acid derivative valued for its unique structural properties and performance as an intermediate. This compound is particularly significant for its role in synthesizing specialized lubricants, surfactants, and polymer additives where specific branching and chain length are required. It serves as a critical raw material for industrial applications in the chemical manufacturing, lubricant formulation, and personal care industries.

Application

• Lubricant & Grease Additive: Acts as a friction modifier and viscosity index improver in synthetic and semi-synthetic lubricants.
• Surfactant Intermediate: Used in the synthesis of specialized anionic and nonionic surfactants for industrial and cleaning applications.
• Polymer & Resin Modification: Serves as a monomer or plasticizer additive to enhance flexibility and processing characteristics of polymers.
• Corrosion Inhibitor Formulation: A key component in oil-based corrosion preventive compounds and coatings.
• Personal Care Ingredients: Employed in the production of esters for emollients and thickeners in cosmetic formulations.
• Metalworking Fluids: Functions as an emulsifier and lubricity agent in cutting and grinding fluids.
