Cellulose ether compositions based on rapidly dissolving, pulverulent, water soluble cellulose ethers contain swellable and suction active superabsorbents to prevent the formation of lumps when dissolved. The cellulose ether composition can be converted into compression moulded pieces which retain the rapid solubility and dissolve without forming lumps.
