Usage
For use as-is with only dilution
Depending on the purpose and conditions of use, dilute the product with tap water so that the concentration of the active ingredients ranges from several mass ppm to several thousand mass ppm.
When blending with other agents to produce sanitizing detergents, etc.
Please check the stability and antimicrobial activity with other ingredients before use.
When used at low temperatures
Turbidity may occur at low temperatures. If turbidity occurs, heat the product to 50-60°C to make it homogeneous before use.
Precautions against misuse
When mixed with other drugs, precipitation may occur depending on the temperature and concentration used. When using this product in combination with other ingredients, check the stability of the mixture beforehand and use it within the range where there are no problems.
Examples of substances that are likely to cause precipitation include the following
Iodine tincture, phenol, sulfosalicylic acid, hydrogen peroxide, silver nitrate, tannic acid, sodium sulfosalicylate, potassium permanganate, potassium dichromate, etc.
