Disinfectants

[Jay and Nancy Mone]

First of all, how are you measuring bacterial growth?  Id be rather 
skeptical that growth was enhanced in the presence of small amounts of 
disinfectants.
As far as how they work, bleach and hydrogen peroxide are both oxidizing 
agents.  They strip electrons from cellular molecules, which alters the 
functions of these molecules.
Doaps and detergents are often called anionic (meaning they carry a net 
negative charge), cationic (carries a net positive charge), or non-ionic 
(no charge).
