White bees wax and lard trigliceride fractions were converted with Me2N(CH2)(3)NH2 to amidoamines and then oxidized with H2O2 to resp. N-oxides. The products were studied for chem. compn. by gel chromatog. and for chem. properties by detn. of activity and mol mass distribution as well as contents of surface active agents and N-oxides. The hydrophilic-lipophilic equil. and soly. parameters were detd. by H-1-NMR spectroscopy.
