Patent

CA 2307625

This invention relates to a process for producing a substantially fibre-free 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 in civil and underground engineering.

L'invention concerne un procédé de fabrication d'une carboxyméthylcellulose sensiblement exempte de fibres, dotée essentiellement de propriétés élastiques, ainsi que son application comme matériau superabsorbant et son utilisation comme agent auxiliaire pour l'établissement d'une rhéologie et d'une rétention d'eau appropriées dans des domaines tels que cosmétique, pharmacie, produits alimentaires et, également, des applications techniques, par exemple, comme additifs pour des peintures, l'étanchéification de câbles et l'utilisation en exploitation souterraine et construction de tunnels.
