Description

2-Octyldecanoic Acid is a branched-chain fatty acid, also known as isostearic acid, valued for its excellent stability and low melting point. This unique structure makes it a versatile intermediate and performance additive in demanding industrial formulations. It is particularly sought after by manufacturers in the lubricants, cosmetics, plastics, and specialty chemicals sectors for its ability to enhance product properties.

Application

• Lubricant & Grease Additive: Used as a friction modifier and to improve the thermal stability and viscosity index of synthetic lubricants and greases.
• Cosmetic & Personal Care Ingredient: Serves as an emollient and thickening agent in creams, lotions, and lipsticks, providing a non-greasy feel and good skin compatibility.
• Polymer & Plastic Additive: Acts as a lubricant and processing aid in PVC and other plastics, improving flow properties and surface finish.
• Metalworking Fluids: Functions as a corrosion inhibitor and lubricity agent in cutting oils and drawing compounds.
• Chemical Intermediate: A key raw material for the synthesis of esters, amides, and salts used in various surfactant and specialty chemical applications.
• Paint & Coating Additive: Employed to improve pigment wetting, dispersion stability, and flow in coating formulations.
