Abstract: A process which can extract a fatty acid from a triglyceride oil includes (a) contacting a triglyceride oil T1 made of a fatty acid with an aqueous solution W1 made of a quaternary ammonium salt and an aliphatic diol having 1 to 8 carbon atoms, where a triglyceride oil phase T2 and an aqueous phase W2 are obtained, where T2 has a reduced content of fatty acids compared to T1 and W2 has an increased content of fatty acids compared to W1; and (b) separating the triglyceride oil phase T2 from the aqueous phase W2. The quaternary ammonium salt includes a quaternary ammonium cation and a basic anion selected among hydroxide, alkoxide, alkyl carbonate, hydrogen carbonate, carbonate, serinate, prolinate, histidinate, threoninate, valinate, aspartate, taurinate, and lysinate.
