  • the air-water jet device is incorporated into a hand washing device.
  • the liquid source may be any water source, either provided to the air-water jet device straight from the water mains, through a pump, through a pressured container holding the water or by any other means, or even by gravity (i.e. by placing the water reservoir above the height of use of the air-water jet.
  • the feed liquid may be any liquid.
  • aqueous composition For regular skin cleansing an aqueous composition is typically preferred.
  • the nozzle for the liquid is called water nozzle herein below, but it is understood that the water nozzle may pass water or any other liquid, including aqueous liquids and other skin treatment composition optionally comprising benefit agents.
  • the air source may be any air source, either provided through a compressor, separate from, or built into the hand washing device, or through a compressed air line, such as often available in hospitals.
  • the air may be heated. It is preferred that the air temperature is at least 30° C., more preferably at least 35° C., still more preferably at least 40° C., but typically less than 70° C., more preferably less than 65° C., or even less than 60° C.
