It is shown that hypothetical neutrino-majoron coupling can suppress neutrino
flavor oscillations in the early universe, in contrast to the usual weak
interaction case. This reopens a window for a noticeable cosmological lepton
asymmetry which is forbidden for the large mixing angle solution in the case of
standard interactions of neutrinos.
