Also behavior of surfactant in the bulk of the solution was studied. Different stabilization efficiency of studied mono-carboxylic acids was explained. The new model for description of small-angle neutron scattering data for magnetic fluids with surfactant excess was proposed and successfully used. Structure parameters of the given systems were obtained by using of the proposed model. It was observed that sharp deterioration of ferrofluids stability is occurred at the surfactant excess bigger than 25 volume %. From experimental results it was obtained that for stearic acid solution in benzene large aggregates is formed at the acid concentration bigger than 5 volume %. Attraction between acids molecules is bigger in the magnetic fluids than in pure solvent that leads to deterioration of magnetic fluids stability.
