What % of hydrogen peroxide in solution?

There is 1% of (food grade 3% H2O2 solution) in the final formulation.

Is this spray in a glass or plastic bottle?

It is in a pharmaceutical grade PET non-BPA bottle. This is the same bottle we have used for the past 15 years in all our nasal products.

Does anyone have a fishy smell to it? Like a fishy after scent? Or maybe my bottle is not right?

I have had several bottles and none of them smelled fishy. I just get the hydrogen peroxide "burn". I think you received a bad bottle. But, things smell differently to different people. The product works for me, although it is a temporary solution to my allergy congestion. Between Sinus Plumber, Nosin, and Flonase, I can get through allergy season.

Do you have msds for it? as some airport might make a fuss for the h2o2

Because the ingredients are all food grade and at low percentages in a distilled water base, it’s actually exempt from MSDS. Just by the ingredient label, they can see this product is basically a saline spray with hydrogen peroxide. If you ever have a problem, contact us directly and we will replace your bottle, but we sell to many airplane travelers and I’ve never heard of a problem. Thanks for the excellent question.
