  • Applications

    3-(2,6,6-Trimethyl-1-cyclohexen-1-yl)-2-propenal is used primarily as an aroma ingredient and fixative in fragrance formulations, helping to retain and diffuse scent in perfumes. In cosmetics and personal care, it often serves as a fragrance component in creams, lotions, and shampoos. In household products, it may be added to cleaners, laundry products, and air fresheners to impart or enhance fragrance. In industrial manufacturing, it is considered an intermediate for the synthesis of downstream aroma compounds and may be incorporated in encapsulation systems or polymer/coating formulations to enable controlled scent release. Given its aldehyde functionality and terpenoid framework, it can also be evaluated as a fragrance modifier in plastics or coatings formulations.
