Abstract (en)

[origin: WO9524526A1] A method of de-inking non-impact printed paper comprises contacting repulped paper with a formulation comprised of a derivatized ethylene oxide/propylene oxide polymer and a petroleum hydrocarbon distillate. The process separates the ink from the paper and agglomerates the separated ink into particles of a size sufficient that they can be efficiently removed from the paper fibers.
