Abstract: For every $ {H_0}$-space (i.e. a space whose rationalization is an $ H$-space) we construct a space $ J$ depending only on $ {H^\ast}(X;{\mathbf{Z}})$ and a rational homotopy equivalence $ J \to X$ (i.e. $ J$ is a universal space to the left of all $ {H_0}$-spaces having the same integral cohomology ring as $ X$ is constructed generalizing the James reduced product. We study also the integral cohomology of $ {H_0}$-spaces and we prove that under certain conditions it contains an algebra with divided powers.
