Question

When using Product Name (20nm Silver Pure) at 1-1.5% for disinfection (killing germs), is it necessary to add anything else besides water to reach 100%?

Answer

Using Silver for Disinfection

When using a liquid silver product like "Silver (2000ppm, Ionic, Colorless Solution, pH 4-6)" or "Nano Silver (2000ppm, Colloidal, Yellow Solution)" at a concentration of 1-1.5% for disinfection, you can add just water to reach 100% if you are creating a simple water-based solution.

However, if you are formulating a more complete product, such as a cosmetic, you will typically need to include other ingredients besides water to achieve the desired formulation properties.

Important Considerations:

  • Compatibility: Be aware of compatibility issues. The silver solutions may be affected by certain ingredients. For example, the "Silver (2000ppm, Ionic, Colorless Solution, pH 4-6)" product description mentions avoiding all types of salt/electrolyte (including EDTA) and cationic surfactants. The "Nano Silver (2000ppm, Colloidal, Yellow Solution)" description also mentions avoiding salt/electrolyte and cationic surfactants.
  • pH: Pay attention to the recommended pH range for the specific silver product you are using to ensure stability.

In summary, while you can dilute the silver solution with just water for a simple disinfectant, creating a full formulation usually involves other ingredients, and their compatibility with the silver is essential.
