guaethol allyl ether

Guaethol allyl ether, also known under synonyms such as carnotene, guaethol allyl ethyl ether, and guaiacyl allyl ethyl ether, is a chemical fragrance ingredient characterized by a clear to pale liquid appearance. It belongs to a class of allyl ethers derived from guaiacol structures and imparts a distinctive floral odor profile with spicy and woody undertones. The compound is referenced in chemical databases such as PubChem and is chiefly sourced through synthetic organic processes designed to control purity and olfactory consistency. It is used mainly in perfumery and fragrance applications where complex floral nuances are desired.

This compound does not occur naturally in large amounts but is manufactured for commercial fragrance use. It provides a medium-strong floral note reminiscent of carnation, enriched with spicy and woody accents. Guaethol allyl ether finds its primary application as a fragrance agent in perfumery formulations and related products. It contributes substantivity, lasting approximately 128 hours at full concentration, supporting sustained olfactory impact. Regulatory guidance from IFRA (Global) permits usage levels up to 1.0000 % in fragrance concentrates, emphasizing controlled and safe application. Not recommended for flavor use, it remains specialized for olfactory enhancement in cosmetic and personal care formulations.

Guaethol allyl ether exhibits specific gravity values ranging from 1.0228 to 1.0288 at 25 °C, indicating a density slightly greater than water. Its refractive index varies between 1.5195 and 1.5255 at 20 °C, consistent with aromatic ether compounds. The compound is soluble in alcohol solvents but insoluble in water, reflecting its nonpolar and moderately hydrophobic character. The flash point is measured at 210 °F (approximately 99 °C), signifying moderate volatility and underlying flammability considerations. These properties influence its behavior during formulation, favoring incorporation into alcohol-based matrices and requiring standard handling precautions for flammable liquids.
