ABSTRACT:
A process is disclosed for deinking pulp which has been made from paper printed with oil based ink. The process uses a surfactant component with and at least one alkoxylated diamine selected from Formula I: ##STR1## where X, Y, W and Z may be alike or different and are each independently selected from the group consisting of
