Performance test
Minimum inhibitory concentration (MIC) against bacteria and fungi
The minimum inhibitory concentration (MIC) of "CATION DMS-75E" against bacteria and fungi is shown in the table below. Please note that these data are measured values for a single product, and values may change when other ingredients are combined.
Minimum inhibitory concentration (MIC, our measured value) against bacteria and fungi
| Bacterial strain | MIC mass ppm (active ingredient) | |
|---|---|---|
| CATION DMS-75E | （Comparative example） Didecyl chloride dimethylammonium chloride | |
| Pseudomonas aeruginosa | 25 | 25 |
| Escherichia coli | 6.3 | 6.3 |
| Staphylococcus aureus | 0.8 | 0.4 |
| Aspergillus niger (black mold) | 6.3 | 6.3 |
Test Method
The minimum growth inhibition concentration test method described in the Handbook of Bacteria and Mold Prevention (Gihoudo Shuppan Co., Ltd.) was followed.
Medium: Normal bouillon liquid medium (for bacteria)
GP liquid medium (for fungi)
Inoculum solution: Approximately 106 CFU/mL
Compatibility with water
Water only
When mixed with water only, "CATION DMS-75E" may thicken, separate into two layers, or become cloudy, depending on the blending ratio.
Compatibility of CATION DMS-75E with water (water only)
| CATION DMS-75E/water ratio (mass ratio) | Appearance of formulation (25°C) |
|---|---|
| 85／15 | Clear liquid |
| 80／20 | Transparent liquid (two-layer separation) |
| 60／40 | Transparent liquid (two-layer separation) |
| 40／60 | Transparent liquid (two-layer separation) |
| 30／70 | Clear viscous liquid |
| 10／90 | Clear viscous liquid |
| 5／95 | Murky-liquid |
| 1／99 | Murky-liquid |
Test Method
"CATION DMS-75E" and water were blended in the ratios listed in the table above, and the appearance was visually observed after one day of standing at 25°C.
Use with other agents
As mentioned above, "CATION DMS-75E" is not water soluble by itself, but can be blended with nonionic surfactants and other agents to form a clear liquid.

Usage
Usage
For diluted use
Depending on the purpose and conditions of use, dilute the product with tap water so that the concentration of the active ingredient is several mass ppm to several thousand mass ppm.
When blending with other agents to produce sanitizing detergents, etc.
Please check the conditions of blending with other ingredients, antimicrobial efficacy, and stability of blending before use.
For long-term storage
White precipitates may occur after long-term storage, but this is due to salt precipitation and does not affect the performance of the product. It will dissolve when mixed with water or other ingredients.
Precautions against misuse
“CATION DMS-75E” is a cationic surfactant and may not perform as expected if combined with anionic agents such as soap or anionic surfactants. Do not use in combination with anionic agents.
Please be sure to read the "Safety Data Sheet" (SDS) for each product and sub-material (chemical) before handling the products listed on this website. The SDS can be obtained from here. https://www.sanyo-chemical.co.jp/products/en/sds/
