  • Patent number: 8648150
    Abstract: The present invention is a method for producing a water absorbent resin which method is a method for producing surface cross-linked water absorbent resin particles, the method including the successive steps of: (a) adding a surface cross-linking agent and water to a particulate water absorbent resin in a mixer; and (b) reacting the resulting water absorbent resin mixture taken out from the mixer with the surface cross-linking agent in a reactor by heating or active energy ray irradiation, water vapor being used as part or all of the water added in the mixer. This makes it possible to provide a method for producing a water absorbent resin in which method a surface cross-linked water absorbent resin that has excellent properties can be obtained efficiently at low cost with high productivity.

  • Patent number: 8642527
    Abstract: The invention provides an aqueous bleaching solution for substrate treatment. The aqueous bleaching solution features a source of oxidant and a plurality of optically functional nanoparticles. The optically functional nanoparticles are nanoparticles in the range of about 0.1 nanometers to about 400 nanometers in size. The aqueous bleaching solution may optionally include one or more an oxidant-stable surfactants and optionally, one or more oxidant-stable polymers, and adjuncts. The optically functional nanoparticles are extremely stable in the aqueous bleaching solution and remain substantially suspended in the aqueous bleaching solution due to their extremely small size despite having an average density greater than that of the bleaching solution.
