  • Applications

    (E,E)-2,6-decadienal, CAS number: 134998-59-7, is regarded mainly as an odorant and aroma ingredient for fragrance applications. In perfumery it can contribute aldehydic, green and fatty notes and is often evaluated for use as a fragrance component in cosmetics and personal care products, as well as in household cleaners and air fresheners. It may also serve as a intermediate in the synthesis of other specialty fragrance compounds used in polymers, coatings, and inks. Where permitted by regulations, it can be explored as a flavor/aroma additive in processed foods.
