What is Isoamyl Alcohol?
Isoamyl Alcohol is a speciality solvent that finds extensive use for flavours and fragrances and is used in the production of many synthetic flavours. Its relatively low eco-tox profile finds it use growing in other areas.

Isoamyl alcohol is used as solvent for the preparation of synthetic apricot, banana, cheery, greengage, malt, orange, plum and whiskey flavours, and is a raw material in the production of synthetic banana oil. It is one of the components of the aroma of the black truffle. It is also used for estimation of fat in milk and milk products.
It is the main ingredient of Kovac’s Reagent used for the bacterial diagnostic Indole Test.
Its blend of properties makes it suitable for use as a foam suppressant, affecting the surface tension of micro-emulsions and causing foam breaking.
As a solvent it is finding increasing use in a wide number of industrial applications. In solvency power, it falls between common hydrocarbon solvents and lower molecular weight ketones. Paraffin wax is soluble in hot Isoamyl Alcohol.
In formulation, some high molecular weight esters and polar plastics incorporate Isoamyl Alcohol based systems eg cellulose esters. Shellac and urea formaldehyde.
It is a diluent in some printing inks, lacquers and gums.
In pharmaceuticals, it is the initial raw material for a number of drug preparations such as Barbamil, Validol, Corvalol and amyl nitrite.
A derivative of Isoamyl Alcohol, the p-methoxycinnamate is used as a UV absorber in some cosmetic formulations, and the product itself finds application as a cosmetic flavouring and in perfume.
