<p>Detergent which is in the form of a powder and contains 5 to 35 % by weight of alkane sulphonates, 2 to 10 % by weight of alkali metal silicates and/or alkaline earth metal silicates and 5 to 75 % by weight of condensed alkali metal phosphates and/or amino polycarboxylic acids. The alkali metal silicates used have an Na2O:SiO2 ratio of less than 1:3.5. The use of the said specific alkali metal silicates makes it possible to produce dry, non-sticky detergents which are in the form of a powder and contain alkane sulphonates.</p> |
