Hi Marti,
Hydrogen Peroxide in cleaning solutions must be ‘stabilized’ in order not to decompose before it is used. In fact, commercial solutions of Hydrogen Peroxide are usually stabilized before they are shipped and stored. So, the Hydrogen Peroxide we buy as an ingredient is already stabilized when we receive it. Hydrogen Peroxide is stabilized with chelating and sequestering agents. These agents are either inorganic/organic phosphates which are somewhat acidic or stannate which is alkaline. Colloidal stannate and sodium pyrophosphate are standard stabilizers. Organophosphonates are also common stabilizers. Don’t let the chemical names scare you. Salty tasting sodium pyrophosphate, for example, is often used as a food additive.
