Analysis of experimental data on the structural relaxation time ${\tau }_{\alpha }$ in various glass formers revealed its universality at the critical temperature $T_c$ of the mode-coupling theory. In most glass formers studied $\ln {\tau }_{\alpha }{(T}_c)=-(6.5\mathrm{}–7.5).$ Possible reasons for such a universality are discussed.
