Hydrogen peroxide is more effective but it is more dangerous.
Peroxide is more harmful if it comes in contact with hands whereas rubbing alcohol is much safer for cleansing hands
Hydrogen peroxide is most dangerous than the rubbing/ 70% alcohol. 70% alcohol and hydrogen peroxide are both antiseptics and disinfectants and rubbing alcohol is used to remove bacteria from medical devices whereas hydrogen peroxide in dilute concentration (3%) to remove stain.
Both are rapidly bactericidal, alcohol prob technically incrementally more rapid but of doubtful real significance. Industrial H2O2 at 30% is pretty aggressive but H2O2 disinfectants are at ~5 % or lower and are not "dangerous." I refer you to an SDs for one such product http://www.cfsph.iastate.edu/Disinfection/Assets/Disinfection101.pdf
What percent of H2O2? 5% is not highly effective bactericidally. . Many Gram negative bacteria have enzymes that can and do degrade H2O2 very quickly. 5% then is not very effective vs. them. However, high concentrations, such as 20% and 40% are stronger and are toxic. These concentrations indeed are dangerous (they burn) as they would burn your skin. For that reason, you may want to go with alcohols.
Regarding alcohols--use >70% EtOH rather than isopropanol (IPA).
IPA is not quite effective until you use 95% active and higher.
If your operating pH near neutral and
Please look at the Clorox product - marketed as a cleaner/disinfectant at < 5% H2O2. Obviously formulation dependent as it's combined with benzyl alcohol that doesn't have disinfectant activity by itself. O.ne could presume synergy. https://www.thecloroxcompany.com/wp-content/uploads/cloroxcommercialsolutionscloroxhydrogenperoxidedisinfectingcleanerjw2015-04-27.pdf
Hydrogen peroxide is more powerful. But in using your disinfectant, it is advisable to look at ideal characteristics of a disinfectant which include and not limited to: effective and stable over the range of pH values, not affect the physical properties, not produce any interaction, inactivate microorganisms quickly, be safe to use, be cost effective to use and so on.
Both are good and effective disinfectants. However, Hydrogen peroxide is harsh when in contact with the skin. It tends to distort the epidermal architecture when used in cleaning wound. Therefore, the surface of application should be taken into consideration when choosing which disinfectant to use.
Hydrogen peroxide is more effective because of its high oxidizing power.
Hydrogen peroxide activity due to from formation on free hydroxyl radicals (OH), wich oxidiye thiol group in enzymes and proteins, is more effective than isopropyl alcohol.
Hydrogen peroxide can also kill fungal spores.
Hydrogen peroxide is effective than 70% EtOH, but EtOH is definitely safer. If you are looking for a disinfectant for environmental cleaning such as lab bench, etc. I do recommend you to choose EtOH or one other option is sodium hypochlorite solution.
Hydrogen peroxide has superior disinfectant efficacy but it have shorter shelf life and can also be corrosive to metals.
