Isoamyl decanoate

Isoamyl decanoate (CAS 2306-91-4), also known as isopentyl decanoate, is a medium-chain fatty acid ester used as a flavoring agent and emollient carrier in food and cosmetic applications.

It delivers a mild, fruity character that blends cleanly into complex flavor and fragrance systems. Its ester structure also makes it effective as a non-polar solvent and carrier for active ingredients.

In food flavoring, isoamyl decanoate contributes fruity, waxy top notes to confectionery, beverages, and dairy formulations where low-intensity background esters are required for the profile.

Cosmetic formulators use it as a skin-feel modifier and carrier oil in serums, sunscreens, and color cosmetics, where it improves spreadability without leaving a heavy residue on the skin.

It functions as a solvent for lipophilic fragrance compounds in perfumery, helping to dissolve and stabilize aromatic blends in leave-on and rinse-off products for various consumer goods.

In lipstick and lip gloss bases, it acts as a diluent for pigment dispersions and wax systems. Isoamyl decanoate is supplied as a clear, low-viscosity liquid for industrial use.

Food-grade and cosmetic-grade specifications are the standard commercial offerings, with food-grade material typically produced to purity levels meeting flavor industry requirements for safety.

Packaging ranges from small drums to IBCs depending on volume requirements. The material should be stored in a cool, dry place to maintain its chemical stability and shelf life.
