dimyrcetol (IFF)

Dimyrcetol (IFF), also known under numerous synonyms including 2,6-dimethyl-7-octen-2-ol and dihydromyrcenol, is a naturally occurring monoterpenoid alcohol used primarily as a fragrance ingredient. This compound possesses a molecular formula of C₁₀H₂₀O and manifests as a clear liquid in its pure form. It is characterized by a fresh, citrus-lime scent complemented by herbal and marine undertones, making it valuable in perfumery and personal care products. The chemical structure and properties of dimyrcetol are documented under PubChem CID 29096. Derived synthetically or isolated from essential oils, it demands appropriate storage conditions to maintain stability. It is commonly employed under the International Flavors & Fragrances (IFF) designation for consistent quality.

Dimyrcetol is found in trace amounts in natural essential oils where related terpene alcohols occur. It is widely utilized as a fragrance agent imparting citrus and lime notes. Its scent profile is particularly suited for fresh lime colognes, shampoos, soaps, detergents, and floral-fresh fragrances. Dimyrcetol's usage levels and safety in fragrance formulations comply with the IFRA Code of Practice (Global), where usage restrictions ensure consumer safety and product stability. Its moderate substantivity requires careful formulation to achieve desired scent longevity in diverse applications.

Dimyrcetol exhibits physical characteristics favorable for fragrance formulation. It is a clear liquid with a moderate specific gravity ranging from 0.857 to 0.866 at 20–25 °C, and a refractive index between 1.434 and 1.439 at 20 °C. The compound possesses a vapor pressure of approximately 0.166 mmHg at 25 °C, contributing to its volatility and odor release. Its estimated log P value around 2.9 indicates moderate lipophilicity, facilitating solvent compatibility, especially in alcohol-based systems. Dimyrcetol has a flash point near 80 °C (176 °F), implying typical handling precautions. Solubility is confirmed in alcohol and estimated moderate in water (~252 mg/L at 25 °C). Proper storage in sealed containers protected from heat and light extends its shelf life beyond 36 months.
