Finely divided, synthetic, crystallised, water-insoluble alkali metal aluminium silicates containing bound water are used. The alkali metal aluminium silicates correspond to the formula (Cat2O)x.Al2O3.(SiO2)y, in which Cat denotes an alkali metal ion, x denotes a number from 0.7-1.5 and y denotes a number from 0.8-6. These silicates have a particle size of 1-12 mu and a calcium binding ability of 100-200 mg of CaO/g of anhydrous active substance. The proportion is 2-30% by weight relative to the total weight of the hair cleaning composition. |
