Washing or cleaning agents, wherein the application of hydrogel layers are produced on hard or soft (especially textile) surfaces, comprising hydrogel having a molecular weight less than 3500 g / mol, wherein the hydrogel is water-soluble at concentrations below the minimum Gelbildungskonzentration, wherein the minimum Gelbildungskonzentration is that concentration at which first forms in a binary solution of water and hydrogel at T = 25 ° C a yield strength of at least 0.05 Pa, and wherein said minimum Gelbildungskonzentration is below 2 wt .-% hydrogel, based on the system consisting of water and hydrogel. This washing or cleaning agent, inter alia, allow the hydrophilization of the surfaces, the generation of a soft handle of textiles as well as the targeted and sustained release of incorporated into the hydrogel active substances, such as. As fragrances or antimicrobials.

L'invention concerne un agent detergent ou de nettoyage liquide renfermant un polysaccharide inhibant le grisage. L'invention concerne egalement l'utilisation de l'agent detergent ou de nettoyage liquide, ainsi qu'un procede pour sa production.
