Nano Silver in Custom Tester Cream

Regarding your question about including nano silver in a custom tester cream formulation, and based on the previous response from our staff:

The ingredients that can be included in a tester formulation are limited to those specifically available for selection on the website's tester page.

While we do have products containing "nano silver" or "silver" in our database, such as:

• Nano Silver 20nm Powder
• Silver (2000ppm, Ionic, Colorless Solution, pH 4-6)
• Nano Silver (2000ppm, Colloidal, Yellow Solution)

Whether any of these can be added to a custom tester cream depends entirely on whether they are listed as selectable options on the tester formulation section of the website. Please check the available options directly on the website to see if nano silver or any silver-based ingredients are listed.
