| abstract |
The invention relates to a washing or cleaning agent, wherein use thereof generates hydrogel layers on hard or soft (in particular textile) 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°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, the generation of a soft touch in textiles and the specific and retarded releasing of active substances embedded in the hydrogel layers, such as aromatic substances or antimicrobial active substances, for example. |
