Abstract
The invention concerns a solid alkalimetal silicate having a molar ratio SiO.sub.2 :M.sub.2 O 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 K.sub.2 O 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.
