Transparent lyotropic ferronematic dispersions are synthesized by admixing a cationic ferrofluid to the lyotropic liquid crystal PL/1D/Wt. The transparency is spontaneous and time-independent. It is observed in zero magnetic field in white and polarized light for disordered layers of ferroliquid crystals of thicknesses ~1 cm in both isotropic and nematic phases. Justification of the low extinction of light in the systems of the lyotropic origin is presented.
