Eudesmol

Updated: 2026-10-10

Overview

Eudesmol is a naturally occurring sesquiterpenoid alcohol with three major stereoisomers (α, β, γ). As a primary constituent of eucalyptus oil and other botanical extracts, it serves as a versatile intermediate in fragrance and therapeutic product manufacturing. The compound has gained industrial significance due to its dual role as a fragrance enhancer and bioactive agent. The global market for eudesmol is expanding, driven by demand for natural ingredients in cosmetics and wellness products. Its sustainable sourcing from renewable plant materials makes it attractive for eco-conscious formulations. Producers typically isolate it through fractional distillation or supercritical CO2 extraction.

Physical and Chemical Properties

Eudesmol's viscosity and low volatility contribute to its value as a fragrance fixative. The α-isomer displays the strongest odor characteristics, described as warm woody with spicy undertones. Its hydroxyl group enables derivatization for specialized applications, such as esterification for enhanced solubility in cosmetic emulsions. Thermal stability tests show decomposition begins at 150°C under atmospheric pressure. Flash point is approximately 110°C, necessitating careful handling during high-temperature processing. The compound exhibits optical activity with [α]D values varying by isomer (+10° to +40° in ethanol).

Main Applications

In perfumery, eudesmol forms the base note in oriental and woody fragrance compositions. It synergizes well with sandalwood and patchouli derivatives. The food industry uses it sparingly as a flavor modifier in herbal candies and beverages at concentrations below 0.01%. Pharmaceutical research investigates its potential as an adjuvant in anti-inflammatory creams, where it may reduce prostaglandin production. Recent studies suggest hepatoprotective effects at concentrations of 5-20 μM in vitro. Cosmetics utilize its antimicrobial properties in natural deodorants and acne treatments.

Safety and Storage

Regulatory status varies by region - generally recognized as safe (GRAS) for fragrance use but requires allergen labeling in EU under Regulation (EC) No 1223/2009. Proper storage in amber glass or stainless steel containers prevents photooxidation, which can generate unwanted carbonyl compounds. Material Safety Data Sheets classify it as a Category 4 irritant. Recommended PPE includes nitrile gloves and vapor masks when handling concentrated forms. Shelf life typically exceeds two years when stored under nitrogen atmosphere at controlled temperatures.

B2B Procurement Guide

Industrial buyers should request chromatograms showing isomer distribution, especially for pharmaceutical applications where specific stereochemistry may be required. Batch-to-batch consistency is critical - require certificates showing <5% variance in key parameters. Consider supplier capabilities for custom derivatization (e.g., acetylation) if direct use is impractical. Bulk shipments (>100kg) often qualify for 15-30% discounts but require verification of temperature-controlled transport conditions. Emerging producers in Brazil and China offer competitive pricing but may lack ISO认证.
