摘要： The invention provides a homogeneous, aqueous, cleaning composition which comprises surfactant and solvent, and is characterized in that it forms a solvent-water emulsion on evaporation of at least a portion of the solvent. In such systems the solvent system is selected such that it comprises: a first solvent component in an amount such that it is present at a level above the miscibility limit of that component with water, and, a second solvent component which is sufficiently volatile that, in use, it evaporates from the composition to leave a mixture of the first solvent component and water, said second solvent component being present at a level such that first solvent component is solubilised in the composition. By using the second solvent to assist in the solution of the first solvent it is possible to obtain compositions which are clear, stable, isotropic compositions. In use, the second, volatile solvent component evaporates from the overall composition and the remaining first solvent component and water phase-separate, thus forming an emulsion, whereby the cleaning action of the first solvent component is potentiated. The emulsion formed generally has a coarse dispersed phase. This yields the advantages of a stable non-emulsion product as regards storage, dosing and manufacture, employs a relatively low level of solvent and provides the cleaning benefits of a free-solvent system.
摘要翻译：本发明提供了包含表面活性剂和溶剂的均匀的含水清洁组合物，其特征在于，在蒸发至少一部分溶剂时形成溶剂 - 水乳液。在这样的系统中，选择溶剂系统，使得其包含：第一溶剂组分，其量使得其以高于该组分与水的可混溶性极限的水平存在;和第二溶剂组分，其具有足够的挥发性，在使用中，其从组合物蒸发以留下第一溶剂组分和水的混合物，所述第二溶剂组分以使得第一溶剂组分溶解在组合物中的水平存在。通过使用第二溶剂来辅助第一溶剂的溶液，可以获得澄清，稳定的各向同性组合物的组合物。在使用中，第二挥发性溶剂组分从总体组合物和剩余的第一溶剂组分和水相分离蒸发，从而形成乳液，从而增强第一溶剂组分的清洁作用。形成的乳液通常具有粗分散相。这产生了关于储存，计量和制造的稳定的非乳液产品的优点，采用相对低水平的溶剂并提供自由溶剂系统的清洁益处。

摘要： In order to improve the dispersion of nonionic surfactant into wash water from a granule in which the nonionic surfactant is carried on a water-insoluble granular material, the nonionic surfactant is intimately blended with a water-insoluble liquid. Preferred water-insoluble liquids include hydrocarbons, for example, paraffins.
