Trimethylolpropane Tricaprylate/Tricaprate

What is Trimethylolpropane Tricaprylate/Tricaprate?

Trimethylolpropane tricaprylate/tricaprate is a synthetic ester formed from trimethylolpropane, a polyol, and a blend of caprylic and capric fatty acids derived from plant or coconut sources. It belongs to the category of emollient esters commonly used in skincare formulations like moisturizers, lotions, and serums. In products, it works by spreading easily across the skin, mimicking natural sebum to lubricate and reduce surface friction. This action helps fill in minor irregularities, promoting a smoother texture while offering a light, quick-absorbing profile that avoids heavy residue. Its branched structure provides a dry-touch finish, making it ideal for modern, lightweight cosmetics where a velvety sensation is desired without oiliness.
