摘要：
A process and composition for deinking waste paper is disclosed. The process comprises administering an alcohol, randomly alkoxylated with a mixture of alkylene oxides to form a surfactant, to a sample of waste paper for which treatment is desired. The surfactant enhances the aggregation and densification of electrostatic toner particles, while promoting foaming in the aqueous slurry.
