Product Application of 1-Hexanol CAS#111-27-3
1-Hexanol is a vital flavour raw material and widely applied in the blending of essential oils including geranium oil, delivering vivid top notes to fragrance compositions. Added in trace dosages to violet, osmanthus, magnolia and ylang-ylang formulas, it brings out and strengthens fresh, tender green aromatic characters.
In the food flavour sector, it is incorporated moderately into coconut, berry and diverse fruit flavour systems. Compliant with China GB2760-86 standard, it is permitted for use as an edible flavour substance, primarily deployed in coconut and berry flavour creations.
Beyond flavour & fragrance fields, 1-Hexanol boasts diversified industrial value. It acts as a solvent and chromatographic analytical reagent, and works as an organic synthesis intermediate. It can be adopted to manufacture surfactants, plasticizers and fatty alcohols. Within pharmaceuticals, it is applied for synthesizing preservatives and sedative products.
