The spray is called "Pathogen Capture and Neutralizing Spray" (PCANS) for now
This data suggest PCANS as a promising daily-use prophylactic against respiratory infections.
The study is paywalled, and the abstract doesn't list its ingredients beyond
The formulation consists of excipients identified from the FDA's Inactive Ingredient Database and Generally Recognized as Safe list to maximize efficacy for each step in the multi-modal approach.
Based on that description, its ingredients might not be very different from Covixyl, though it claims to be much more effective.
Edit: Apparently its already for sale, I included some details in a comment
This is a pre-print for a study that was done with mice. I love y'all, but don't go replacing your normal precautions with untested alternatives just yet.
Edit: I was shocked that no one else was able to read the full text of the article yet I could. I guess that Bypass Paywall for Firefox is damn good. The best I could do for you all is a copy-paste job because the website won't let me print out a PDF or anything.
Oof yeah this is pretty early in development. I do like the 100% survival rate in their experimental group vs 0% survival in the control group, it seems like it might have some potential.
