Isotridecyl Isononanoate is a synthetic ester valued for its emollient properties, lightweight texture, and ability to enhance product spreadability. It softens and smooths the skin by forming a protective barrier that prevents moisture loss. Unlike heavier oils or emollients, this ester absorbs quickly into the skin, delivering hydration without a greasy or sticky after-feel. It is commonly used in facial moisturizers, anti-aging creams, and body lotions. In its raw form, Isotridecyl Isononanoate appears as a colorless to pale yellow liquid and has a faint characteristic odor. This ingredient is easy to incorporate into various formulations without altering the product’s overall appearance. The chemical formula of Isotridecyl Isononanoate is C22H44O2.

What is ISOTRIDECYL ISONONANOATE used for?
Isotridecyl Isononanoate is used in cosmetics as a lightweight emollient and skin-conditioning agent, providing smoothness and moisture without a greasy feel. It is commonly found in skin care products like lotions, creams, and serums, where it softens the skin and enhances product spreadability. In hair care, Isotridecyl Isononanoate adds shine and smooths the hair, improving manageability and reducing frizz without weighing it down. Its ability to dissolve and disperse pigments and UV filters makes it useful in sunscreens, foundations, and lipsticks, ensuring even application and a long-lasting, silky finish.
Origin
Isotridecyl Isononanoate is made by the esterification reaction between isotridecyl alcohol (a branched alcohol) and isononanoic acid (a branched fatty acid). This chemical reaction is catalyzed under controlled temperature conditions, where water is eliminated as a byproduct. Once the ester is formed, it is purified to obtain the final ingredient.
