Abstract: The adsorbent has a high absorption capacity for liquid to pasty ingredients of detergents and cleaners and has the following components: (a) 60 to 80 per cent by weight of a synthetic sodium silicate which is capable of cation exchange and contains bound water, (b) 0.1 to 8 per cent by weight of sodium silicate of the composition Na2O : SiO2 = 1 : 2 to 1 : 3.5, (c) 3 to 15 per cent by weight of a mixture of two different polyacrylic acids which have a different viscosity number, (d) 8 to 18 per cent by weight of water which can be removed at a drying temperature of 145 DEG C, (e) 0 to 5 per cent by weight of a nonionic surfactant containing polyol ether groups, where the adsorbent has an average particle size of 0.2 to 1.2 mm and the particles with a size of less than 0.05 mm do not comprise more than 2 per cent by weight and the particles with a size of more than 2 mm do not comprise more than 5 per cent by weight, and the bulk density is 400 to 700 g/l.
