Question

Can Nano Silver 20nm Powder be used in the production of laundry detergent for the following purposes:

  • To claim germ-killing (antimicrobial) properties after washing?
  • To reduce musty odors in fabrics after washing?

Answer

Yes, Nano Silver 20nm Powder can be used in the production of laundry detergent to provide antimicrobial benefits and reduce musty odors.

Benefits and Usage:

  • Antimicrobial Properties: Nano Silver is highly effective at inhibiting the growth of bacteria, fungi, and viruses. This helps in sanitizing the fabric during and after the wash.
  • Odor Reduction: Musty smells in laundry are often caused by the growth of bacteria and mold on damp fabric. By controlling these microorganisms, Nano Silver helps prevent odors from developing.
  • Usage Rate: The recommended usage rate is 0.01% - 0.1%.
  • Mixing: Since it is a powder and insoluble, it can be dry-blended directly into powder detergent formulations. Ensure thorough mixing to achieve even distribution throughout the product.

Considerations:

  • Appearance: The powder is dark gray. However, at the recommended low usage rates, it typically does not affect the color of the detergent or stain the clothes. It is always recommended to perform a patch test or a small-scale wash test.
  • Claims: While Nano Silver has proven antimicrobial properties, specific "disinfectant" or "germ-killing" claims on your final product packaging may be subject to local regulations regarding biocides and household hazardous substances. You should verify the regulatory requirements in your specific region.
