Definitions

  • the present invention relates to a method and a composition for cleaning hard surfaces, to obtain a protective layer for robust water sheeting effect and/or a long lasting effect for cleaning. Moreover, the invention relates to a process for making the hard surface cleaning composition.
  • Forming a water sheeting layer during cleaning and after cleaning may deliver such benefits.
  • the hard surface will dry easily due to the water spreading area being larger upon sheeting. Also drying will be more uniform such that unappealing water mark will not be formed onto the hard surfaces, giving the consumer an appealing appearance, even when the hardness of water is high. The end cleaning result will be better.
  • the soil particulates will be distributed uniformly on the hard surface instead of aggregated within the water marks, due to the uniform water film. Therefore, another benefit is that the hard surface has visually cleaner appearance. Thus the period between cleaning can be prolonged, and so save effort and time for consumers.
  • Hard surface for the purposes of the present invention means any surface comprising a hard material such as glass, glazed ceramics, metal, stone, plastics, lacquer, wood, or combination thereof. Typically, the hard surface is in a household including window, kitchen, bathroom, toilet, furniture, floor, or the like.
