Product Description
1-Hexanol is a colorless liquid with a boiling point of 157 °C and a relative density d₄²⁰ ≈ 0.819. It is readily miscible with ethanol, propylene glycol, and most oils, giving it broad compatibility across flavor, fragrance, and personal-care systems. Its aroma is a fresh green note reminiscent of young shoots and leaves, with subtle winey, fruity, and fatty undertones.
1-Hexanol and its carboxylic acid esters occur naturally in trace amounts in citrus fruits, berries, tea leaves, and a variety of essential oils — including geranium, lavender, and violet leaf oils — as well as in banana, apple, and strawberry aromas. This natural occurrence makes it a valuable ingredient in flavor and fragrance compositions.

Application Scenarios
Flavor and fragrance. 1-Hexanol is a natural constituent of essential oils such as geranium oil, contributing fresh green top notes. In perfume compositions, it is added in trace amounts to violet, osmanthus, magnolia, and ylang-ylang bases to introduce a fresh, leafy green character. In food flavors, it is used at low dosage in coconut, berry, and other fruit flavor systems.
Industrial and chemical uses. It also serves as a solvent and chromatographic reference standard, and as an intermediate in organic synthesis for surfactants, plasticizers, and other fatty-alcohol derivatives, as well as certain pharmaceutical intermediates (including preservative and sedative-type compounds).
Regulatory status. 1-Hexanol is an approved edible flavoring under China's GB 2760 standard, mainly for coconut and berry flavors.
