The invention relates to a washing or cleaning agent, wherein use thereof generates hydrogel layers surfaces, comprising a hydrogel former having a molecular weight less than 3500 g/Mol, wherein the hydrogel former is water-soluble at concentrations below the minimum gel formation concentration, wherein the minimum gel formation concentration is the concentration at which a yield point of at least 0.05 Pa is formed in a binary solution of water and hydrogel former at T=25&#xb0; C., and wherein said minimum gel formation concentration lies below 2 wt % of hydrogel former, relative to the system consisting of water and hydrogel former. The washing or cleaning agents according to the invention enable the hydrophiliation of surfaces, and the specific and retarded releasing of active substances embedded in the hydrogel layers, such as aromatic substances or antimicrobial active substances, for example.
