    • 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. The optically functional nanoparticles provide at least one optical functional benefit to the bleaching solution owing to their uniform and stable suspension throughout the solution, including such benefits as uniform light absorption, light and radiation scattering, fluorescent emission, phosphorescent emission, coloration, and visual aesthetic benefits and the like. Further, optically functional benefits include those benefits provided to a substrate or surface treated with the aqueous bleaching solutions whereby the optically functional property is transferred either temporarily or permanently to the substrate or surface following contact with bleaching solutions containing the optically functional nanoparticles.
    • 本发明提供了用于底物处理的水性漂白溶液。 含水漂白溶液具有氧化剂源和多个光学功能纳米颗粒。 光学功能纳米颗粒是尺寸在约0.1纳米至约400纳米范围内的纳米颗粒。 含水漂白溶液可以任选地包括一种或多种氧化剂稳定的表面活性剂和任选的一种或多种氧化剂稳定的聚合物和助剂。 光学功能性纳米粒子在水性漂白溶液中非常稳定,并且由于其极小的尺寸而保持基本上悬浮在含水漂白溶液中,尽管其平均密度大于漂白溶液的平均密度。 光学功能纳米颗粒由于其在整个溶液中均匀稳定的悬浮液而对漂白溶液提供至少一种光学功能有益效果,包括均匀的光吸收,光和辐射散射,荧光发射,磷光发射,着色和视觉美学等优点 利益等。 此外,光学功能优点包括提供给用水性漂白溶液处理的底物或表面的那些益处,由此在与含有光学功能纳米颗粒的漂白溶液接触之后光学功能性质暂时或永久地转移到基底或表面。

    • A laundry additive composition is provided that includes at least one zeta potential modifier, a fluoropolymer, a hydrophobic agent with a melting point or glass transition temperature below 100° C., and an antimicrobial active for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel, as well as imparting microbiocidal or microbiostatic properties to the fabric and/or washing machine surfaces. Laundry additive compositions can be used as a pretreatment prior to washing, through soaking a fabric or garment. Alternately, they can be added to a washing treatment liquor that comprises either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh fabric protection benefits imparted to the fabric. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits and/or refresh the microbiocidal or microbiostatic properties imparted to fabrics and/or washing machine surfaces.
