Procedure

30.2 g of 5,8,11,14,17-cis-eicosapentaenoic acid (EPA, purity >90%) are treated with 12.1 of choline hydroxide according to one of the procedures described in examples 1 to 3. After charcoal treatment EPA choline salt is thus obtained with a nearly theoretical yield. The product is water-soiuble and its physicochemical and analytical characteristics conform to the expected values.
