Triisodecyl Trimellitate
What is Triisodecyl Trimellitate?
Triisodecyl trimellitate is a synthetic ester formed from trimellitic acid and branched-chain isodecyl alcohols, belonging to the class of trimellitate plasticizers adapted for cosmetic formulations. Primarily used in makeup products like lipsticks and foundations, as well as skincare items such as creams and lotions, it acts as an emollient by depositing a thin, flexible film on the skin's surface. This film lubricates, reduces friction for smoother application, and provides a non-greasy, velvety texture. As a skin conditioning agent, it helps maintain the skin's barrier integrity indirectly through its occlusive-like properties when combined with other ingredients, promoting even distribution and stability in emulsions. Its high molecular weight limits penetration, focusing effects on the outer skin layers for enhanced wear and comfort.
