Definitions

  • the present invention relates to a powder detergent composition.
  • Household cleaners are used in various places and situations in the living environment, and therefore the dirt they are used to remove varies widely from dirt that is easy to remove, such as dust and food spills, to dirt that is very difficult to remove, such as denatured oil dirt.
  • strong alkaline cleaning properties are required for denatured oil dirt in the kitchen, while for floors with dirt that has a small dirt load, a cleaner that has a lower surfactant concentration and does not leave an unpleasant feeling such as sliminess or foam residue is required, and it is not easy to satisfy all of these versatile usability requirements.
  • Hand washing is suitable for cleaning not only the overall dirt attached to the fibers, but also for cleaning difficult-to-remove dirt, for example, organic dirt such as sebum dirt attached to collars and inorganic dirt such as mud attached to socks.
  • many workers wash textile products using detergent, for example, a cleaning solution obtained by dissolving powder detergent in water, but in addition to high cleaning power, workers are also required to have a slippery feeling on the clothes that makes it easy to rub them by hand or wash them with a brush, that is, a clean feeling.
