Usage Percentage and Amount of Nano Silver Powder in Spray
คำถาม
I am making a 200ml spray formulation using `Nano Silver 20nm Powder`.
1. I calculated that using 1% would require 2 grams of the powder. Is this calculation correct?
2. What is the recommended usage percentage for `Nano Silver 20nm Powder` in a spray formulation?
คำตอบ
Nano Silver Usage in 200ml Spray
You are correct that 1% of 200ml (assuming the density is close to water, where 1ml ≈ 1g) is 2 grams.
However, based on the product information for Nano Silver 20nm Powder, the recommended usage rate is 0.01-0.1%.
Using 2 grams in 200ml would result in a 1% concentration, which is higher than the recommended range.
For a 200ml spray, the recommended amount of Nano Silver 20nm Powder is between 0.02 grams (at 0.01%) and 0.2 grams (at 0.1%).
It is advisable to follow the recommended usage rates for optimal results and safety.
