The colourfastness of wholly or partially dyed detergent and cleanser shaped bodies which contain builders, bleaching agents and other conventional ingredients of detergents and cleansers, as well as at least one dye that is not resistant to bleaching can be significantly improved, if the areas of the shaped body, in which the dye that is not resistant to bleaching also contain paraffin. This effect of colour stabilisation is especially pronounced in shaped bodies which are free of phosphates and which contain citrates. |
