cassis oxime 10%

Cassis oxime 10%, chemically known as 2,4,4,7-Tetramethyl-6,8-nonadien-3-one oxime, is a synthetic fragrance compound notable for its distinctive fresh floral and cassis odor profile. This material belongs to a class of oxime derivatives characterized by their capacity to impart green, fruity, and natural blackcurrant-like aromas in perfumery. The compound has the molecular formula C₁₃H₂₃NO and a molecular weight of approximately 209.33 g/mol. It is typically supplied as a 10% solution, commonly referred to under the trade name Labienoxime (Givaudan). Cassis oxime 10% is sourced through chemical synthesis and is valued in fragrance formulations for its ability to add complexity and depth to fruity and green scent accords. More detailed chemical data can be found via linked entries such as PubChem.

Cassis oxime 10% is not naturally occurring but synthesized for use in fragrance applications. It is widely employed as a fragrance agent due to its fresh cassis, floral, and green aromatic properties. This compound is effective in enhancing the realism and tenacity of blackcurrant, grapefruit, and herbal accords. It blends well with ingredients such as methyl pamplemousse, paradiasamide, and various lactones to enrich peach, pineapple, and tropical fruit notes. Its usage complies with IFRA (Global) standards, which recommend maximum concentrations of 0.5% in fragrance concentrates. The ingredient is not authorized for flavoring, limiting its potential use primarily to perfumery and cosmetic formulations.

Cassis oxime 10% exhibits a moderate lipophilicity with an estimated logP value near 4.14, suggesting good compatibility with alcohol-based solvents commonly used in fragrance formulations. It is soluble in alcohol and slightly soluble in water at about 0.6 mg/L at 25°C. The material demonstrates good stability in alcoholic solutions, antiperspirant sprays, detergents, soaps, and toiletries under varying pH conditions, but shows moderate to poor stability in highly alkaline or bleach-containing environments. Its flash point is measured around 100°C (212°F), indicating relatively low volatility and safety under typical handling conditions. These physical and chemical characteristics contribute to its durability and substantivity on fabric and skin, enhancing fragrance longevity.
