The present invention relates to pulverulent water-swellable hydrophilic polymers such as are employed, for example for the absorption of water and aqueous solutions, in particular body fluids such as blood and urine, to which have been added, to reduce dusting, one or more auxiliaries, the vapour pressures of which are not more than 0.1 mbar at 20??? C. and the melting points of which are not mor
