gardenia acetal

Gardenia acetal is a synthetic fragrance compound with the molecular formula C₁₃H₁₈O₂, classified chemically as 2,4,6-trimethyl-4-phenyl-1,3-dioxane. It appears as a colorless to pale liquid with a medium-strength floral odor characterized by fresh, citrus, and gardenia-like notes. Also known by various synonyms including Floropal, Floracetal, and Vertacetal, this compound is widely used in perfumery as a key green-floral ingredient. The linked PubChem resource provides further chemical and structural information. Gardenia acetal is typically synthesized for fragrance applications rather than extracted from natural sources, enabling consistent quality and olfactory effects in formulated products.

Gardenia acetal does not occur naturally but is a synthetic molecule designed for use as a fragrance agent in cosmetic and perfumery products. It contributes distinct citrus-clean, fresh green-floral notes that evoke gardenia petals and complementary hints of grapefruit and chrysanthemum. This compound finds application in various product forms including body lotions, shampoos, soaps, powders, and cleaning agents where its odor remains stable and vibrant. The fragrance industry utilizes gardenia acetal to impart freshness and complexity to floral and citrus accords. Usage guidance aligns with IFRA (Global) standards, permitting concentrations up to 6% in fragrance concentrates while recommending against flavor use.

Gardenia acetal has a moderate boiling point range of 278 to 279°C at standard atmospheric pressure, reflecting its stability under typical formulation conditions. Its vapor pressure of 0.007 mmHg at 25°C indicates low volatility, facilitating long-lasting scent substantivity, which has been measured at approximately 68 hours at full strength. The compound exhibits intermediate lipophilicity with an estimated logP of 2.9, aiding solubility in alcohols and partial solubility in water, although generally considered poorly water-soluble. Its flash point is relatively high at 237°F (approximately 114°C), supporting safe handling in manufacturing. These properties contribute to its favorable performance as a robust and stable fragrance ingredient compatible with diverse cosmetic matrices.
