摘要： Waste printed, cellulosic fibrous material is deinked by using a biodegradable de-inking agent which is non-toxic to aquatic life, said agent comprising an ethoxylated aliphatic mono-ol having about 14-15 carbon atoms in the aliphatic chain and about 8-12 ethyleneoxy units per mole of said mono-ol or an ethoxylated aliphatic di-ol having from 14 to 30 carbon atoms in the aliphatic chain and from 8 to 24 ethyleneoxy units per mole of said di-ol wherein the hydroxy groups in the di-ol are present on adjacent non-terminal carbon atoms in the aliphatic chain.
