Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper, but has also found use as a disinfectant and as an oxidizer. Hydrogen peroxide in the form of carbamide peroxide is widely used for tooth whitening (bleaching), both in professionally- and in self-administered products. Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays important roles in host defense and oxidative biosynthetic reactions.Industry ChemicalsTextile&Leather Chemicals Food Additive Specifications Textile ChemicalsItemsIndustrial useFood gradeStandardGB 1616-2003GB 22216-2008H2O2 concentration(m/m)% ≥35%50%30%/35%Free acid as H2SO4(m/m)% ≤0.0400.0400.02Evaporation residue(m/m)% ≤0.0800.0800.060Stability% ≥979798Total carbon(as C)(m/m)% ≤0.0250.0350.0080Nitrate (as NO3)(m/m)% ≤0.0200.025--Phosphoric(asPO4)(m/m)% ≤--0.0050Stannum (as Sn)(m/m)% ≤--0.0010Ferro (as Fe)(m/m)% ≤--0.00005Lead (as Pb) % ≤--0.0004Arsenic (As) % ≤--0.0001 Less ...
