    摘要: A liquid deinking composition comprising (a) a fatty acid mixture containing 40 to 90 weight % of saturated fatty acids having 12 to 14 carbon atoms and less than 60 weight % of saturated fatty acids having 16 to 18 carbon atoms, (b) a nonionic surfactant with HLB of 2 to 12 in a proportion of (a)/(b)=5/95 to 40/60 (weight ratio), and (c) 0 to 20 weight % (based on the composition) of water. No crystals of fatty acids are precipitated at ambient temperatures, and the separation, solidification or precipitation of crystals due to a temperature change is not caused. Further, the handling property is improved because of the liquid form.
