Tridecyl Isononanoate
What is Tridecyl Isononanoate?
Tridecyl Isononanoate is a synthetic ester formed from tridecyl alcohol, a C13 fatty alcohol, and isononanoic acid, a branched-chain carboxylic acid. It belongs to the category of emollients and skin conditioning agents in cosmetics. This ingredient functions by creating a lubricious barrier on the skin surface, which fills in micro-roughness to promote smoothness and improve the glide of formulations during application. Its branched molecular structure ensures a dry, non-oily touch while facilitating even distribution in products like lotions, serums, and makeup. In formulations, it helps stabilize emulsions and enhances sensory attributes such as silkiness. Derived through esterification processes, it mimics natural skin lipids to maintain suppleness without heaviness, making it suitable for daily-use items across various skin types.
