REDUCED concentrations are not only a bad deal if you do the math you find you really are just paying MUCH more $$ for mostly just water. Worse, it also means someone diluted it – you don’t know how or with what – and it means they are not buying 35% – and Food Grade is NOT produced except in 35% and 50% concentration (50% can NOT be purchased at a consumer level). Lower concentrations are actually FAR more expensive and are very risky to your health in terms of quality. We HIGHLY recommend against lower concentrations and EVERY study done has ONLY been based upon 35% CONCENTRATION. There ARE good reasons to buy and use ONLY 35% Food Grade Hydrogen Peroxide – not the lower concentrations people highly dilute with tap water in their home or apt and labeled as “Food Grade,” whether it is or not – – not just for actual cost savings due to dilution – but also you don’t know what you really are getting with home or apartment based businesses using tap water to dilute what ever actual hydrogen peroxide quality they are using.
