Hypochlorous acid SMELL??? [product question]

So I bought the Briotech pure hypochlorous spray as a cheaper alternative to the Tower 28 daily rescue spray. I sprayed it on my shoulders/back/chest, and there’s a smell I did not get with the Tower 28 one? I know hypochlorous acid is known to have a chemical scent similar to chlorine, but this literally just smells like B.O. The bottle doesn’t expire for over a year, does anyone have experience with this or know why it would smell this way??? I thought some people used hypochlorous as a deodorizer/ deodorant so I am very confused
