Abstract
An N-alkylpolyhydroxyamine salt of an n-6 or n-3 essential fatty acid (EFA) that is beyond the 6-desaturation step, or of any polyunsaturated fatty acid, other than those belonging to the n-6 and n-3 series, having 16 to 26 carbon atoms and up to six double bonds, the double bonds being in the cis or trans configuration, the salt being formed with the fatty acid either as such or in the form of a covalent derivative, through the carboxyl group, of a bifunctional compound itself having a free acid function.
