I was skeptical about the 'no sting' claim because salt water usually hurts me, but the baking soda buffer makes a huge difference. It feels incredibly smooth, like water.
These little packets are life savers for trips. I threw a handful in my dopp kit for a weekend in dusty Palm Springs. So much easier than carrying a jar of salt around.
When I have a cold and my nose is already raw from blowing it, this is the only mix I can use. It doesn't irritate the lining at all. Very soothing.
No grit left at the bottom of the bottle. I drop it in, give it one shake, and it's perfectly dissolved. High quality stuff.
I didn't realize regular table salt had anti-caking agents until I read this page. Switching to this pharmaceutical grade mix feels much cleaner. No iodine taste either.
