Why is HOCl more efficient at killing pathogens?

Hypochlorous Acid (HOCl) vs. Sodium Hypochlorite (Chlorine Bleach)
Hypochlorite ion carries a negative electrical charge, while hypochlorous acid carries no electrical charge. The hypochlorous acid moves quickly, able to oxidize the bacteria in a matter of seconds, while the hypochlorite ion might take up to a half hour to do the same. Germ surfaces carry a negative electrical charge which results in a repulsion of the negatively charged hypochlorite ion to the area of the germ surfaces, making hypochlorite ion less effective at killing germs. The ratio of the two compounds is determined by the relative acidity (pH) of the water. Water treatment specialists can adjust the pH level to make hypochlorous acid more dominate, as it is more efficient at killing bacteria. The hypochlorous acid's lack of electrical charge allows it to more efficiently penetrate the protective barriers surrounding germs.
