The aim is to improve the pourability and penetration power of powdered washing, bleaching or cleaning agents composed of a plurality of powdered components. This aim has been achieved by a universally usable additive in the form of a powdered, pourable product, containing anionic surfactants and builders, obtained by drying a flowable aqueous suspension of its contents, containing 2 % - 25 % by wt. of a synthetic anionic surfactant of the sulphate and/or sulphonate type, up to 5 % by wt. of soap, if the anionic surfactant is of the sulphonate type, and up to 10 % by wt. of soap if an additional or sole anionic surfactant of the sulphate type is present, not more than 7.5 % by wt. of a non-ionic surfactant, up to 10 % by wt. of amorphous or non-lamellar crystalline alkaline silicate, up to 50 % by wt. of inorganic salt containing water of crystallization, releasing water of crystallization at temperatures in the range of 1 DEG C to 45 DEG C, 20 % - 75 % by wt. of inorganic water-insoluble builders, consisting of alkali alumosilicateand/or crystalline lamellar alkali silicate and a total of less than 7 % by wt. of water, which can be expelled by heating to 200 DEG C. |
