Description

Fatty Acids, Coco, Esters With Trimethylolpropane is a synthetic ester derived from coconut fatty acids and trimethylolpropane, serving as a versatile non-ionic surfactant and emollient. This compound is valued for its excellent lubricity, oxidative stability, and compatibility with a wide range of cosmetic and industrial formulations. It is primarily sought by manufacturers in the personal care, lubricant, and polymer industries for its multifunctional performance.

Application

• Primary emollient and skin-conditioning agent in cosmetic creams, lotions, and sun care products.
• Key ingredient in the formulation of high-performance synthetic lubricants and metalworking fluids.
• Plasticizer and compatibilizer for PVC and other polymer systems to improve flexibility.
• Intermediate for the synthesis of more complex surfactants and ester quats.
• Additive in textile auxiliaries and fiber lubricants.
• Base fluid for environmentally acceptable lubricants (EALs) and biodegradable formulations.
• Conditioning agent in hair care and color cosmetic products.

Quality Control

Our Fatty Acids, Coco, Esters With Trimethylolpropane is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant industry standards. A comprehensive Certificate of Analysis (COA) documenting key parameters such as acid value, saponification value, and hydroxyl value is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., nitrogen blanket) is recommended. Keep away from strong acids and organic solvents.
