Isotridecyl Isononanoate
What is Isotridecyl Isononanoate?
Isotridecyl Isononanoate is a synthetic ester created by combining isotridecyl alcohol, sourced from branched fatty alcohols, with isononanoic acid. Its unique branched structure results in low viscosity, providing a dry, velvety touch distinct from heavier oils. Primarily used in lightweight cosmetics like serums, moisturizers, foundations, and sunscreens, it functions as an emollient by replicating skin lipids to temporarily fill surface irregularities and boost product spreadability. As a skin conditioning agent, it helps preserve the skin's natural suppleness and flexibility, facilitating better delivery of other formula components without a greasy residue. This makes it suitable for everyday products emphasizing quick absorption and comfortable wear.
