A machine dishwashing composition is provided wherein two specifically defined nonionic surfactants are utilized which in combination have been shown through empirical research to surprisingly yield improved results. One of the nonionic surfactants is an alcohol alkoxylate (as defined) and the other nonionic surfactant is a block copolymer of ethylene oxide and propylene oxide (as defined). The use temperature for efficient cleaning while using the composition extends over a broad range up to at least 140°F. in the absence of deleterious foaming even in the presence of protein soil (e.g., egg and/or milk soil).
Further, an aqueous rinse-aid composition for kitchen utensils is provided wherein an anionic hydrotrope and a blend of two specifically defined nonionic surfactants are utilized which has been shown through empirical research to surprisingly yield improved results. One of the nonionic surfactants is an alcohol alkoxylate (as defined) and the other nonionic surfactant is a block copolymer of ethylene oxide and propylene oxide (as defined). The composition is suitable for use at a temperature of up to at least 180°F. in the absence of excessive foaming, spotting and film formation. The components of the composition exhibit good compatibility during storage even if elevated temperatures are experienced thereby maintaining reliable performance upon usage. Rapid high velocity rinsing at a high temperature is made possible in the absence of deleterious foam generation to yield dishes and tableware that can be readily dried without the need for the time consuming hand removal of deleterious spots and/or film.
本发明提供了一种机器洗碗组合物,其中使用了两种特别定义的非离子表面活性剂,通过经验性研究表明,这两种非离子表面活性剂的组合能令人惊讶地产生更好的效果。其中一种非离子表面活性剂是醇烷氧基化物(如定义),另一种非离子表面活性剂是
环氧乙烷和环氧
丙烷的嵌段共聚物(如定义)。在使用该组合物时,有效清洗的使用温度范围很广,可达到至少 140 华氏度,即使在存在蛋白质污垢(如鸡蛋和/或牛奶污垢)的情况下也不会产生有害泡沫。
此外,我们还提供了一种用于厨房用具的
水性冲洗组合物,其中使用了阴离子
水溶液和两种特别定义的非离子表面活性剂的混合物。其中一种非离子表面活性剂是醇烷氧基化物(如定义),另一种非离子表面活性剂是
环氧乙烷和环氧
丙烷的嵌段共聚物(如定义)。该组合物适合在温度至少高达 180°F 的条件下使用,不会产生过多的泡沫、斑点和成膜。即使在温度升高的情况下,组合物的各成分在储存期间也能表现出良好的相容性,从而在使用时保持可靠的性能。在不产生有害泡沫的情况下,可以在高温下进行快速高速冲洗,从而使餐具和食具可以很容易地干燥,无需费时用手去除有害斑点和/或薄膜。
