Mixing and Shelf Life of Spray Formula

Yes, this formula can be mixed by combining all the ingredients together and packaging it in a spray bottle.

Regarding the shelf life:

• Microbial Stability: The staff mentioned that the infused waters (which are the base here) already contain preservatives. With clean mixing procedures and sealed packaging, the product should be stable against microbial growth for 1-2 years.
• Efficacy: The exact duration for which the product's efficacy remains unchanged cannot be determined without actual testing over time.

So, regarding your question about storing it for 1 year after opening, if the mixing process is clean and the packaging is kept sealed when not in use, microbial stability should be fine for 1-2 years. However, the performance or effectiveness of the ingredients might change over that period, which would require testing to confirm.
