Measures against new coronavirus infections

The Printemps Hotel Group uses "stable sodium hypochlorite" products that are certified by the Ministry of Health, Labor and Welfare and are used in the medical field.

Weakly alkaline and highly sterilizing effect!

Weakly alkaline pH 8.3

  • Highly safe for the human body

  • Extremely high sterilization effect

  • A product that improves on the shortcomings of existing sodium hypochlorite


​The new coronavirus has protrusions called spikes on its surface, which are the second layer of lipid membranes. This spike is made of protein and can only be destroyed with "alcohol disinfectant" or "alkaline sodium hypochlorite" . When weakly acidic hypochlorite water is sterilized by air spray, this bilayer lipid membrane cannot be destroyed, so it is weakly alkaline and stable sodium hypochlorite for viruses with these two total lipid membranes. Can be said to be effective.
