All made from edible food ingredients.
It does not contain petroleum-derived synthetic disinfectants such as benzethonium chloride, benzalkonium chloride, IPMP (isopropylmethylphenol), and CPC (cetylpyridinium chloride / cetylpyridinium chloride) that are chemically synthesized from light oil.
They are strictly restricted in the percentage of compounding in the product by the Ministry of Health, Labor and Welfare, and have side effects on their action.
However, in reality, among petroleum-based synthetic bactericides, overseas studies have shown that a concentration of 0.1% or more is effective, but in Japan, the concentration permitted in product formulations is 0.05% or less. There was a problem that it was difficult to expect actual clinical effects as a product.
On the other hand, even at low concentrations where no effect can be expected, disorders and side effects due to long-term use may occur, and there have been difficult issues in actual clinical use.
