Description

Fatty Acids, C8-18 And C18-Unsatd., iso-Bu Esters is a synthetic ester derived from a blend of saturated and unsaturated C8-C18 fatty acids esterified with isobutyl alcohol. This versatile chemical intermediate is valued for its excellent solvency, lubricity, and hydrophobic properties, making it a key component in high-performance formulations. It is primarily sought by manufacturers in the lubricants, metalworking fluids, plastics, and personal care industries for its ability to modify surface properties and enhance product performance.

Application

• Lubricant and Metalworking Fluid Additive: Acts as a friction modifier, emulsifier, and corrosion inhibitor in synthetic and semi-synthetic lubricants and coolants.
• Plasticizer and Processing Aid: Used as a secondary plasticizer and internal lubricant in PVC and other polymer processing to improve flexibility and mold release.
• Personal Care and Cosmetic Ingredient: Functions as an emollient and skin-conditioning agent in creams, lotions, and makeup products.
• Industrial Cleaner and Degreaser: Serves as a key solvent and surfactant in heavy-duty cleaning formulations for machinery and parts.
• Textile and Leather Auxiliary: Employed as a softening agent, lubricant, and water-repellent finish in fiber processing and leather treatment.
• Coating and Ink Additive: Enhances flow, leveling, and substrate wetting in solvent-based coatings and printing inks.
