mcp acetate

MCP acetate, chemically recognized as 2-methyl-3-(2-methyl-5-isopropenylcyclopentenyl)propyl acetate, is a synthetic ester used in fragrance formulations. It appears as a clear oily liquid offering a distinctive oily woody aroma with amber, patchouli, and warm undertones. Known also by synonyms such as methyl cyclopentenolone acetate and methylcyclopentenolone acetate, this compound is characterized by a complex cyclopentenyl-based structure linked to an acetate group. It is primarily sourced via chemical synthesis techniques tailored to fragrance industry standards. MCP acetate is documented in chemical databases including PubChem, where its molecular structure and physicochemical properties are detailed. Its organoleptic qualities contribute significantly to woody and amber olfactory notes in perfumery blends.

MCP acetate is employed predominantly as a fragrance agent due to its warm, woody, and amber scent profile. It serves as a substitute for natural ingredients such as ambrette oil, providing similar olfactory characteristics while facilitating sustainable sourcing and consistency. This compound complements accords of sandalwood, lily of the valley, and patchouli by imparting oily and resinous nuances. Biological occurrence in nature is not typical, as it is synthetically produced to meet consistency demands in fragrance formulations. MCP acetate aligns with IFRA (Global) standards, which guide its safe usage within fragrance products and specify concentration limits. Its versatility makes it valuable in fine fragrances, personal care products, and household scenting applications where ambergris or woody notes are desired.

MCP acetate is an oily liquid with solubility characteristics consistent with other ester-based fragrance ingredients. Its chemical structure, featuring a cyclopentenyl ring and an acetate functional group, influences its volatility and odor diffusion properties. These characteristics enable a balance between a persistent woody base note and the warmth typical of amber scents. The compound's refractive index and boiling point suggest moderate stability under typical formulation and storage conditions. Its lipophilic nature favors integration into oil-based perfume bases while maintaining blend stability. These physico-chemical properties support its role as an amber and woody note enhancer in complex fragrance constructions.
