A method of oxidative molecular cleavage of a fatty compound, includes:&#x2014;forming a liquid composition, referred to as a fatty composition, consisting of at least one aliphatic carboxylic acid, the fatty composition including the fatty compound; characterized in that it then involves:&#x2014;adding, to the fatty composition, a solution of at least one quaternary ammonium salt in water capable of forming an emulsion from the fatty compound and water, then;&#x2014;adding, to the emulsion, a liquid solution of at least one tungstophosphoric acid in a composition including hydrogen peroxide (HO), in such a way as to form, in situ in the emulsion, a quantity of a phase-transfer catalyst, formed from tungstophosphoric acid and at least one quaternary ammonium from the quaternary ammonium salt(s), and to allow the oxidative molecular cleavage of the fatty compound.
