    摘要： The invention concerns a solid alkalimetal silicate having a molar ratio SiO₂:M₂O from about 1.5 to about 3, in which M is an alkalimetal substantially consisting of sodium and potassium. The silicate contains from about 1 and up to about 5% by weight of K₂O based on the dry material and the water content being from about 16 to about 25% by weight based on the total weight.
    Further, the invention concerns a method of its preparation, its use and a cleaning agent composition containing the silicate above.

    摘要翻译： 本发明涉及一种固体碱金属硅酸盐，其具有摩尔比SiO 2 :M 2 O约1.5至约3，其中M是基本上由钠和钾组成的碱金属。 硅酸盐基于干物质含有约1重量％至约5重量％的K 2 O，并且基于总重量，水含量为约16至约25重量％。 此外，本发明涉及其制备方法，其用途和含有上述硅酸盐的清洗剂组合物。
