Abstract (en)
[origin: WO02053198A1] The invention relates to a water-absorbent composition containing, in relation to its weight, between 30 and 100 wt. % of non-water soluble hydrogels which can swell in water. Said hydrogels comprises the following characteristics: a centrifuge retention capacity (CRC) of at least 24 g/g; a saline flow conductivity (SFC) of at least 80 x 10<-7> cm<3>s/g; and a free swell rate (FSR) of at least 0,15 g/g and/or a maximum vortex time of 160s.
