What stabilizer additives are in commercial solutions of hydrogen peroxide and why?
The main function of stabilizers is to reduce catalytic decomposition induced by transition metals and other contaminants. If the product is diluted, as in 3% topical solutions, or is used in formulations that could accelerate decomposition, a higher level of stabilization is required. If high purity is required, low levels of stabilizers must suffice. Stabilizers are traditionally metal chelating agents and colloids including stannates, pyrophosphates and organophosphonates. Stabilizer levels vary from 0 to several thousand mg/l each depending on the grade.
