fruity cyclopentanone
Fruity cyclopentanone is a medium-strength fragrance compound with a fruity, floral, and lactonic scent profile used mainly in perfumery.
General Material Description
Fruity cyclopentanone, also known by synonyms such as 2,2,5-trimethyl-5-pentylcyclopentanone and commercial names like Veloutone, is a synthetic organic compound primarily utilized as a fragrance ingredient. This molecule features a cyclopentanone core substituted with methyl and pentyl groups, yielding the molecular formula C13H24O and a molecular weight of approximately 196.33 g/mol. It presents as a stable, colorless liquid with a distinctive medium-strength odor characterized by fruity notes reminiscent of peach and apricot, complemented by floral jasmine, lactonic nuances, and a hint of lavender. The compound is accessible primarily through synthetic routes and is listed under PubChem (CID 103402). Its stability and complex scent profile make it highly valuable in fragrance formulations aiming for soft floral and fruity characteristics.
Occurrence, Applicability & Potential Uses
Fruity cyclopentanone does not occur naturally in significant quantities and is synthesized for commercial use predominantly as a fragrance agent within fine fragrances and personal care products. It provides a versatile floral and fruity character reminiscent of jasmine, honeysuckle, tuberose, lilac, and woody notes, enhancing diverse perfume categories. Under the IFRA (International Fragrance Association, Global) Code of Practice, its use is recommended up to 2% concentration in fragrance concentrates. This compound is not intended for flavor applications. Its stability contributes to long-lasting olfactory effects in formulations, expanding its applicability to products such as shampoos, soaps, and shower gels, where it also imparts herbal and lavender nuances.
Physico-Chemical Properties Summary
Fruity cyclopentanone exhibits a moderate volatility with a vapor pressure of approximately 0.026 mmHg at 25°C and a relatively high estimated logP value of 4.16, indicating substantial lipophilicity. Its flash point, measured by the Tag Closed Cup method, is around 194°F (90°C), suggesting moderate flammability under heat. The compound is soluble in alcohol and has limited water solubility estimated at 8.956 mg/L at 25°C. Its chemical stability allows usage in multiple product types at trace to low-percent levels without significant degradation. These properties influence formulation strategies, favoring incorporation into alcohol-based perfume bases and ensuring persistence on skin or substrates without rapid evaporation or breakdown.
