    • Selected combinations of particular solvents and surfactant are compatible with lipolytic enzymes in that after a first application of the compositions of the present invention the cleaning effort required to remove soils in subsequent cleaning cycles is reduced. The invention provides a cleaning composition for hard surfaces which comprises: a) a solvent having at least one alcoholic hydroxyl group and at most one ether linkage, b) a surfactant, and, c) a lipolytic enzyme. It is believed that the selected solvents interact with the enzyme to somehow prevent the surfactant from interfering with the activity of the enzyme, in a synergistic interaction in that the addition of either enzyme or solvent to a surfactant increases cleaning effort as compared with surfactant alone whereas the addition of both solvent and surfactant reduces cleaning effort as compared with surfactant alone.
    • 特定溶剂和表面活性剂的选定组合与脂肪分解酶相容,因为在第一次施用本发明的组合物后,减少在随后的清洁循环中去除污垢所需的清洁力。 本发明提供了一种用于硬表面的清洁组合物,其包括:a)具有至少一个醇羟基和至多一个醚键的溶剂,b)表面活性剂,和c)一种脂肪分解酶。 相信所选择的溶剂与酶相互作用以某种方式防止表面活性剂干扰酶的活性,在协同相互作用中,因为向表面活性剂中加入酶或溶剂会增加清洁力,而与单独使用表面活性剂相比, 与单独使用表面活性剂相比,溶剂和表面活性剂的添加减少了清洗力。

    • An improved process is described for obtaining triazacyclononanes (I), especially 1,4,7-trimethyl-1,4,7-triazacyclononane. The first step involves reacting diethylenetriamine (DET) with a sulfonylation agent to form a sulfonamidated DET, in an aqueous medium with an inorganic base. In a second step, but preferably within the same reactor vessel without isolating intermediates, the sulfonamidated DET aqueous mixture is contacted with an aprotic organic solvent in the presence of a cyclizing unit such as ethylene glycol ditosylate or ethylene dibromide, thereby resulting in a cyclized sulfonamidated triamine compound. Thereafter the protecting groups are removed and the amine is alkylated, preferably within a single reaction vessel without isolation of intermediates.
    • 描述了用于获得三氮杂环壬烷(I),特别是1,4,7-三甲基-1,4,7-三氮杂环壬烷的改进方法。 第一步涉及在具有无机碱的水性介质中使二亚乙基三胺(DET)与磺酰化剂反应形成磺酰胺化的DET。 在第二步中,但优选在不分离中间体的相同反应器容器内,在环化单元例如乙二醇二甲苯磺酸酯或二溴乙烷存在下,将磺酰胺化的DET含水混合物与非质子有机溶剂接触,由此导致环化磺酰胺化 三胺化合物。 此后,除去保护基团,并将胺烷基化,优选在单个反应容器内,而不分离中间体。

    • 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.
    • 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。
