This invention relates to a process for producing a substantially fibre-fre e carboxymethyl cellulose which predominantly exhibits elastic properties, to the use thereof as a superabsorbent material, and to the use thereof as an adjuvant substance for achieving suitable rheological and water retention properties for the cosmetics, pharmaceutical and food sectors, and for industrial applications, e.g. as an additive for coating materials, for the sealing of cables and for use in tunnelling and i n civil and underground engineering.
