  A composition for disinfecting contaminated drinking water. The composition can include a disinfecting agent for disinfecting or sanitizing the water and a masking agent for masking or minimizing undesired characteristics of the disinfecting agent, such as taste and odor. The disinfecting agent can be a halogen-based disinfecting agent, such as a chlorine-based disinfecting agent. The masking agent can be a chlorine-compatible masking agent or flavorant, such as a citrus fruit derived flavor. The composition can also include a substrate. The substrate can be a clay, zeolite, water-soluble carrier, water-insoluble carrier, or mixtures thereof. The flavorant can be loaded onto the substrate. The composition can include other components, such as a primary coagulant, a coagulant aid, a bridging flocculant, a polymeric material, an alkali agent, an autocatalytic oxidant, and mixtures thereof.

  一种用于对受污染的饮用水进行消毒的组合物。该组合物可包括用于对水进行消毒或杀菌的消毒剂，以及用于掩盖或尽量减少消毒剂的不良特性（如味道和气味）的掩蔽剂。消毒剂可以是卤素消毒剂，如氯消毒剂。掩蔽剂可以是与氯兼容的掩蔽剂或调味剂，如柑橘类水果衍生香料。组合物还可以包括一种基质。基质可以是粘土、沸石、水溶性载体、水不溶性载体或它们的混合物。调味剂可以加载到基质上。该组合物还可包括其他成分，如初凝剂、助凝剂、架桥絮凝剂、聚合物材料、碱剂、自催化氧化剂及其混合物。

  [EN] The invention provides inter alia a liquid electrostatic spray composition consisting of: (i) a non-aqueous component which is substantially free of propellants and ethanol; and (ii) 0.1-25% w/w water component being water as adjuvant to modify the viscosity and/or resistivity and/or surface tension of the composition optionally together with additional electrolytes; the composition containing one or more active ingredients; and the composition having at 20°C a resistivity in the range 1 x 10³ to 1 x 10⁶ Om, a viscosity in the range 1 to 5 cP and a surface tension in the range 20-40 mN/m.
  [FR] L'invention concerne entre autres une composition de pulvérisation électrostatique liquide contenant (i) un constituant non aqueux pratiquement exempt d'agents de propulsion et d'éthanol et (ii) entre 0,1 et 25% en poids d'un constituant aqueux, à savoir de l'eau, en tant qu'adjuvant afin de modifier la viscosité et/ou la résistivité et/ou la tension superficielle de la composition, facultativement au moyen d'électrolytes supplémentaires. Cette composition renferme au moins un ingrédient actif et présente à 20°C une résistivité comprise dans une fourchette de 1 x 10³ à 1 x 10⁶ Om, une viscosité allant de 1 à 5 cP, et une tension superficielle se situant entre 20 et 40 mN/m.
