Citronellol is an indispensable raw material for the formulation of all kinds of rose-based floral flavours and can be used in almost all cosmetic products.

In the ether, benzene or other organic solvents, in the conditions of constant access to hydrogen, with sodium metal reduction of citronellol and obtained.

In the ethanol solution by adding the catalyst ferrous sulfate, in the platinum black catalysed hydrogenation of citral and get geraniol, and then by the above method to get citronellol.
