 How to make antiseptic solutions

  • For norovirus, sterilization with sodium hypochlorite is effective.
  • Sodium hypochlorite is included in commercial "home chlorine-based bleach" (approximately 5% of density).

Precaution when we handle antiseptic solution

  • Please perform ventilation enough.
  • As you provide stimulation for skin, please use plastic gloves. In addition, please do not use for disinfection of finger, skin.
  • As you provide bleaching, discoloration does not use to curious clothing, and please sterilize by other methods (hot water disinfection more than 85 degrees Celsius).
  • When you used for metal because there is property to let metal corrode, please wet-wipe carefully.
  • Because disinfection effect decreases when organic matter including filth (vomit, flight) is left, please sterilize filth after having been eliminated beforehand.
  • Because effect may come off with progress of time, let's use up antiseptic solution each time.
