What is Benzalkonium Chloride?

It is a chemical preservative that is used in some nasal sprays, like Ocean Nasal Spray, widely prescribed by doctors. The chemical has been banned in some European countries and has been shown to be harmful to skin, eyes and nasal membranes and to aggravate rhinitis medicamentosa.

To soothe irritated or dry sinuses we recommend Sinus Survival Herbal Nasal Spray as a soothing botanical alternative.
