Review on 🔄 Supersmile Powdered Mouth Rinse: Clinically Proven Breath Freshener and Teeth Whitener - TSA Approved On-the-Go Packets - No Sugar or Alcohol by Kerri Edwardz

I buy it and only use it when I travel. It's nice to be able to keep up with oral hygiene without having to lug around a bottle of mouthwash (which is mostly water, and water is heavy). Couple this with the TSA's restrictions on carrying liquids in carry-on baggage on flights. These active packages win every time. Personally, I split the pack into two uses (pour half the powder into a glass and mix the water in the glass). I think using a fully concentrated solution is like using baking soda and tastes bad. Half the dose isn't that bad.
