Dissolving DeoMax and Using Silver as Preservative in Mouthwash

Based on the conversation with the staff:

• Question 1: How to dissolve DeoMax?
  The staff recommends mixing only DeoMax with water first. Use a mixer at 500 RPM for approximately 5 minutes, without applying heat. The staff tested this method and found that DeoMax can dissolve completely in water this way, even at high concentrations.

• Question 2: How to keep DeoMax dispersed?
  If DeoMax is properly dissolved in water using the method above, it should not settle. If it still settles after adding other ingredients, it might indicate incompatibility between some ingredients in the formula, as initially suggested by the staff. The staff did not provide a specific method to keep it dispersed if precipitation occurs in the final formula, but ensuring complete initial dissolution in water is the key first step.

• Question 3: Can Nano Silver or Micro Silver be used instead of Global Guard in a liquid mouthwash? If not, which thickener can be used to disperse silver for preservation?
  According to the staff, Nano Silver or Micro Silver are not suitable for use as a preservative in a liquid mouthwash format because they will settle over time if left standing, which reduces their effectiveness in controlling microbial growth within the product. If the purpose is to help kill germs in the mouth before use, shaking the bottle would be appropriate. However, for preservation within the mouthwash product itself, this settling is problematic. The staff did not suggest a thickener for this purpose, as they advised against using silver for preservation in this liquid format.
