Description

Fatty Acids, C16-18, Isotridecyl Esters are a high-purity synthetic ester derived from palmitic and stearic acids. This compound serves as a versatile, non-ionic intermediate and functional fluid with excellent solvency and lubricity properties. It is essential for formulators in the lubricants, plastics, and personal care industries seeking stable, low-volatility ingredients. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• Lubricant & Metalworking Fluid Additive: Acts as a friction modifier and emulsifier in synthetic and semi-synthetic lubricants, drawing compounds, and coolants.
• Polymer & Plasticizer Intermediate: Used in the synthesis of specialized plasticizers and as a processing aid to improve flow and mold release in polymer formulations.
• Personal Care & Cosmetic Emollient: Functions as a skin-conditioning agent and emollient in creams, lotions, and makeup, providing a non-greasy feel.
• Industrial Cleaner & Degreaser Formulation: Serves as a key solvent and coupling agent in heavy-duty industrial and institutional cleaning products.
• Textile & Leather Processing Aid: Employed as a softener, lubricant, and anti-static agent in fiber processing and leather finishing.
• Paint & Coating Additive: Enhances pigment wetting, flow, and leveling in solvent-based coatings and printing inks.
