3-Methyl-2-cyclopenten-1-one

3-Methyl-2-cyclopenten-1-one, commonly known as Cyclotene, is a cyclic ketone with a distinctive sweet, caramel-like, maple, and roasted cocoa aroma that occurs naturally in coffee, chocolate, and other thermally processed foods. It is widely used in cosmetic and personal care formulations as a fragrance ingredient to impart warm, gourmand, and confectionery-type scent profiles. Formulators value Cyclotene for its ability to add depth and sweetness to fragrance blends at relatively low use concentrations, making it a cost-effective choice for creating indulgent, food-inspired scent experiences in products such as body lotions, lip balms, and hair care.
