For any pair M, N of von Neumann algebras such that the algebraic tensor product M ⊗ N admits more than one C*-norm, the cardinal of the set of C*-norms is at least 2א0. Moreover, there is a family with cardinality 2א0 of injective tensor product functors for C*-algebras in Kirchberg's sense. Let ${\mathbb B}$=∏nMn. We also show that, for any non-nuclear von Neumann algebra M⊂ ${\mathbb B}$(l2), the set of C*-norms on ${\mathbb B}$ ⊗ M has cardinality equal to 22א0.
