Description

Triethylene Glycol Caprate-Caprylate is a synthetic ester derived from triethylene glycol and a blend of capric and caprylic fatty acids. This versatile chemical intermediate is valued for its excellent solvency, low volatility, and favorable skin-feel properties, making it a key component in high-performance formulations. It is primarily sought by manufacturers in the personal care, cosmetics, and pharmaceutical industries for its role as an emollient, solvent, and carrier.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and solvent in skin creams, lotions, sunscreens, and makeup products, providing a smooth, non-greasy texture.
• Pharmaceuticals: Used as a solubilizer and carrier in topical drug delivery systems and ointments.
• Industrial Lubricants & Plasticizers: Serves as a base or additive in synthetic lubricants and as a plasticizer for certain polymers.
• Chemical Synthesis: Functions as a biodegradable intermediate or reactant in the production of specialty esters and surfactants.
• Cleaning & Degreasing Formulations: Employed as a solvent in industrial and institutional cleaning products due to its efficacy on oils and greases.
