clary acetate
Clary acetate is an herbal, woody fragrance ingredient used predominantly as a clary sage and cypress oil replacer in perfumery.
General Material Description
Clary acetate is a synthetic fragrance compound classified chemically as an acetate ester with the molecular formula C12H20O2. It appears as a clear liquid, notable for its warm, herbal, and woody odor profile. Known also under names like plinyl acetate and by its IUPAC denomination cyclopentanol, 1,2-dimethyl-3-(1-methylethenyl)-, acetate, this compound is listed in controlled vocabularies such as PubChem. It is primarily derived via chemical synthesis involving cyclopentanol derivatives and acetic acid esters. Due to its distinct aromatic properties, clary acetate finds application in fragrance formulations, where it supplements or replaces natural oils. As an ester, it shares typical solubility behavior and volatility traits characteristic of many aromatic esters used in perfumery.
Occurrence, Applicability & Potential Uses
While clary acetate does not occur naturally in significant amounts, it is a valuable synthetic counterpart to natural clary sage and cypress oils. This compound is utilized extensively as a fragrance agent providing herbal, pine, woody, and fir notes. It is recognized by standards including IFRA (Global), which governs safe usage levels in fragrance concentrates. Its applications often include fine fragrances, personal care products, and household scents where herbal and woody nuances are desired. The ester’s odor profile supports versatility in replacing or enhancing natural counterparts, offering formulators consistent olfactory qualities and supply stability.
Physico-Chemical Properties Summary
Clary acetate exhibits a boiling point range between 219 and 223 °C at atmospheric pressure, contributing to its moderate volatility in formulations. Its specific gravity lies between 0.945 and 0.965 at 20 °C, and its refractive index ranges from 1.451 to 1.471 at the same temperature, reflecting its optical density. The compound’s vapor pressure of 0.81 mmHg at 25 °C indicates sufficient volatility to be effective in vapor-phase scent release. Flash point measured at 181 °F (approximately 83 °C) suggests an intermediate flammability hazard requiring consideration in handling. It is soluble in alcohol but has limited solubility in water. These properties influence formulation behavior, stability, and application methods in fragrance systems.
FAQ
What is clary acetate and what are its primary characteristics?
Clary acetate is a synthetic fragrance compound known for its warm and herbal woody odor. Chemically, it is an acetate ester with the formula C12H20O2 and is used predominantly as a replacer for clary sage and cypress oils in perfumery. Its clear liquid appearance and distinct scent profile make it suitable for imparting herbal, pine, and woody notes in various fragrance products.
How is clary acetate used and where is it typically applied?
Clary acetate is utilized mainly as a fragrance ingredient in perfume compositions and personal care products. It acts as a synthetic alternative to natural oils, providing consistent aromatic effects of clary sage and cypress. Its usage extends to household fragrances as well, supporting herbal and woody scent accord constructions. Regulatory standards such as IFRA (Global) provide guidance on maximum usage concentrations in fragrance concentrates, emphasizing its role in safe and controlled application.
What regulations and safety information exist for clary acetate sourcing and use?
Clary acetate is regulated under fragrance industry standards including the IFRA Code of Practice (Global), which recommends usage limits up to 8% in fragrance concentrates and restricts its use in flavor applications. Safety classifications from European authorities identify it as an irritant with precautionary recommendations to avoid skin contact. Toxicological data indicate oral and inhalation toxicities require exposure controls, and it is categorized under GHS as an irritant without additional hazard pictograms. Suppliers typically provide safety data sheets outlining handling and storage requirements.
