patchouli cyclohexanol
Patchouli cyclohexanol is a fragrance compound with an earthy, vetiver-like scent used primarily in perfumery applications.
General Material Description
Patchouli cyclohexanol is an alicyclic alcohol recognized chemically as 2-(1,1-dimethylethyl)-4-methylcyclohexanol with the molecular formula C11H22O. It appears as a colorless liquid characterized by an earthy and vetiver-like odor, reflecting its notable presence in fragrance compositions. This compound, also known under synonyms such as rootanol and o-tert-butyl-4-methylcyclohexanol, is derived synthetically for use primarily as a fragrance material. Due to its distinct olfactory properties, patchouli cyclohexanol integrates well into accords seeking to replicate natural earthiness and woody notes. It is indexed in chemical registries like PubChem where it is linked under CID 106739, providing structured data to the scientific and formulation community.
Occurrence, Applicability & Potential Uses
Patchouli cyclohexanol does not occur naturally but is synthesized for application in fragrance agents. It serves as a substitute or enhancer for natural oils such as cypress, fir needle, or galbanum, contributing an earthy and woody character reminiscent of patchouli and vetiver. Its odor profile is suitable for reinforcing balsam, herbal, and root accords. The compound has been evaluated under IFRA (Global) standards, which guide its maximum safe concentration at 2.0% in fragrance concentrates. Due to its unique aromatic qualities, it finds use in perfumes, personal care products, and potentially in flavoring contexts emphasizing pine or pea-like notes; however, regulatory guidelines currently restrict its application in food flavoring.
Physico-Chemical Properties Summary
Patchouli cyclohexanol demonstrates a moderate molecular weight around 170 Da and exhibits a calculated partition coefficient (log P) near 3.6, indicating its lipophilic nature. Its vapor pressure at 25 °C is low, approximately 0.024 mmHg, reflecting limited volatility, conducive to sustained scent release in formulations. The flash point, measured at 100 °C (212 °F), suggests it has a moderate flammability risk under standard handling conditions. This compound is soluble in alcohols and somewhat soluble in water with an estimated solubility of 105 mg/L at 25 °C. These properties influence its formulation behavior, making it compatible with many perfumery bases and solvents while requiring consideration for safety measures during manufacture and use.
FAQ
What is patchouli cyclohexanol and how is it used in perfumery?
Patchouli cyclohexanol is a synthetic aromatic compound classified as a cyclohexanol derivative, known for its earthy and vetiver-like odor qualities. It is primarily used as a fragrance agent to replicate or enhance natural earth and woody scents in perfumes and personal care products. Its distinctive aroma allows perfumers to create accords with balsamic, herbal, and root character, often substituting for more variable natural extracts.
Where does patchouli cyclohexanol occur naturally and what are its key applications?
This compound does not occur naturally and is manufactured synthetically for fragrance use. It is applied mainly in perfuming agents where it replaces or complements natural essential oils such as cypress, fir needle, or vetiver. Its applications extend to formulations requiring earth, mint, or pine notes. While it has some flavor-like attributes resembling pea or pine, regulatory standards currently advise against its use as a flavoring agent.
What regulations and safety standards apply to patchouli cyclohexanol?
Patchouli cyclohexanol is regulated under IFRA (Global) standards, which recommend usage limits of up to 2.0% in fragrance concentrates to ensure consumer safety. It is classified as an irritant to skin and eyes per European hazard labeling, necessitating adequate handling precautions. Toxicity data are limited, and users should follow guidelines including avoidance of direct skin and eye contact. Comprehensive safety information is accessible via regulatory bodies such as ECHA in the EU and RIFM assessments.
