Trimethylolpropane Triethylhexanoate

What is Trimethylolpropane Triethylhexanoate?

Trimethylolpropane triethylhexanoate is a synthetic ester formed by reacting trimethylolpropane, a branched polyol alcohol, with ethylhexanoic acid derived from natural fatty acids. This produces a clear, odorless liquid with a low viscosity, ideal for cosmetic applications. It belongs to the class of emollient esters used in skincare products like lotions, creams, foundations, and sunscreens. In formulations, it acts by lubricating the skin surface, reducing friction for better application, and creating a protective barrier that minimizes water evaporation. Its branched structure ensures a dry, non-oily feel, blending well with silicones and oils to improve stability and sensory qualities. This ingredient excels in lightweight formulas, promoting even distribution and a silky after-touch without heaviness.
