Tridecyl Trimellitate

What Tridecyl Trimellitate is & what it does

Tridecyl Trimellitate is a synthetic ester formed from trimellitic acid and tridecyl alcohol. In cosmetic and sunscreen formulas it functions as an emollient and skin-conditioning agent that gives products a smooth, spreadable feel. Its larger, branched structure makes it useful as a non-greasy emollient and texture enhancer.

What does Tridecyl Trimellitate do in skincare?

Tridecyl Trimellitate is a synthetic ester used as an emollient and skin-conditioning agent. It gives products a smooth, spreadable feel and helps improve texture without a heavy or greasy finish. In sunscreens and creams it mainly contributes to the sensory and emollient qualities of the formula.

Is Tridecyl Trimellitate comedogenic?

There is limited public data specifically rating Tridecyl Trimellitate for comedogenicity, so a firm rating cannot be given. As a large, branched ester it is often chosen as a lighter-feeling emollient. If you are acne-prone, monitoring how your skin responds to the full product is the most practical approach.

Is Tridecyl Trimellitate natural or synthetic?

Tridecyl Trimellitate is synthetic, produced by combining trimellitic acid with tridecyl alcohol to form an ester. It is not obtained directly from a plant or animal source. This kind of tailored ester is made to deliver consistent emollient and texture properties.
