  • Applications

    3-Methyl-gamma-decalactone is a fragrance ingredient widely used in perfumery to impart fruity notes, notably peach and apricot, and to contribute to fruit profiles in flavor applications under controlled use. In cosmetics and personal care, it is commonly employed as a fragrance component for products such as moisturizers, shampoos, and soaps. In household products, it serves as a fragrance additive in detergents, fabric softeners, and cleaners. It is also used in coatings, finishes, and inks as a fragrance additive to impart fruity aroma, and may function as an intermediate in the synthesis of other aroma compounds.
