Definitions

  • the present invention relates to the cleaning of industrial or domestic industrial hard surfaces, in particular of the ceramic, tiling or glass type, aimed at imparting hydrophilic properties to them.
  • a more particular subject of the invention is the use of polymers having both properties of interaction with the hard surface and hydrophilic properties to give the latter remanent hydrophilization properties so as to avoid the subsequent presence of traces due in particular to the drying of the drops of water deposited on said surface.
  • detergent formulations allow effective cleaning of hard industrial, domestic or community surfaces. They generally consist of an aqueous solution of surfactants, in particular nonionic and anionic surfactants, alcohol (s) to facilitate drying, and optionally sequestering agents and bases to adjust the pH.
  • surfactants in particular nonionic and anionic surfactants
  • alcohol (s) to facilitate drying
  • sequestering agents and bases to adjust the pH.
  • a major shortcoming of these detergent formulations is that the subsequent contact of the hard surface with water can lead to the presence of traces during drying. This contact with water after applying detergent can come, for example, from rainwater in the case of windows, mains water on a bathroom tile, or rinse water when cleaning requires rinsing. They can also come from drying dishes in the open air in the case of detergent formulas for cleaning dishes by hand, or from drying dishes automatically in the case of detergents for dishwashers .
  • said formula can either be used in the cleaning cycle (detergent formula) or during rinsing (rinsing liquid).
