Abstract
The invention concerns a fatty alcohol obtainable by a method which consists in reducing the carbonyl function of a vegetable or animal oil, the method consisting in reacting said vegetable or animal oil with appropriate amounts of polymethylhydroxysiloxane (PMHS) in the presence of a catalytic system prepared from a metal salt or complex and a reduction agent, followed by hydrolysis of the resulting siloxane with a basic agent and separating and purifying the desired alcohol thus formed. Said alcohol can be used in a perfume composition, in particular as solubilizing agent.
