  • Patent number: 6267842
    Abstract: A water-based treatment agent for tissue paper suppresses any feeling of slipperiness or wetness in ordinary tissue paper and toilet paper so the paper has a dry touch, ample smoothness, and a clean, smooth, tactile impression. It also provides the paper with a superior softness. The water-based treatment agent consists of a silicone oil emulsion in which crosslinked silicone particles with a mean particle size of 0.01-100 &mgr;m are contained in silicone oil droplets with a mean particle size of 0.05-500 &mgr;m, which are dispersed in water. The particle size of the crosslinked silicone particles is smaller than the particle size of the silicone oil droplets.
