Hydrogen Peroxide
CAS Number: 7722-84-1
Molecular Formula: H2O2
Molecular Weight: 34.01
Hydrogen Peroxide
Hydrogen Peroxide Concentrate USP Grade Specifications
H2O2 --- 34.01 --- CAS 7722-84-1
Hydrogen Peroxide Concentrate contains not less than 29.0 percent and not more than 32.0 percent, by weight, of H2O2. It contains not more than 0.05 percent of a suitable preservative or preservatives.
Acidity: Dilute 25 g with water to 250 mL, and mix thoroughly. Take 25 mL of the solution, add phenolphthalein, and titrate with 0.10 N sodium hydroxide: not more than 2.5 mL is required for neutralization.
Chloride: 1.5 g diluted with water to 25 mL shows no more chloride than 0.10 mL of 0.020 N hydrochloric acid (0.005%).
Other requirements: It responds to the Identification test and meets the requirements of the tests for Nonvolatile residue, Heavy metals, and Limit of preservative (90 mL of it being used) under Hydrogen Peroxide Topical Solution.
Hydrogen Peroxide Solution (30 per cent) BP Ph Eur Grade Specifications
Ph. Eur. --- CAS 7722-84-1
Action and use: Antiseptic; deodorant.
DEFINITION
Content: 29.0 per cent m/m to 31.0 per cent m/m of H2O2.
1 volume of hydrogen peroxyde solution (30 per cent) corresponds to about 110 times its volume of oxygen. A suitable stabiliser may be added.
CHARACTERS
Appearance: Colourless, clear liquid.
IDENTIFICATION
A. To 1 mL add 0.2 mL of dilute sulfuric acid and 0.25 mL of 0.02 M potassium permanganate. The solution becomes colourless with evolution of gas.
B. To 0.05 mL add 2 mL of dilute sulfuric acid, 2 mL of ether and 0.05 mL of potassium chromate solution and shake. The ether layer is blue.
C. It complies with the requirement for the content of H2O2.
TESTS
Acidity: To 10 mL add 100 mL of water and 0.25 mL of methyl red solution. Not less than 0.05 mL and not more than 0.5 mL of 0.1 M sodium hydroxide is required to change the colour of the indicator.
Organic stabilisers: Maximum 500 ppm.
Shake 20 mL with 10 mL of chloroform R and then with 2 quantities, each of 5 mL, of chloroform R. Evaporate the combined chloroform layers under reduced pressure at a temperature not exceeding 25C and dry in a desiccator. The residue weighs a maximum of 10 mg.
Non-volatile residue: Maximum 2 g/L.
Allow 10 mL to stand in a platinum dish until all effervescence has ceased, cooling if necessary. Evaporate to dryness on a water-bath and dry at 100-105C. The residue weighs a maximum of 20 mg.
Hydrogen Peroxide Topical Solution USP Grade Specifications
H2O2 --- 34.01 --- CAS 7722-84-1
Hydrogen Peroxide Topical Solution contains, in each 100 mL, not less than 2.5 g and not more than 3.5 g of H2O2. It contains not more than 0.05 percent of a suitable preservative or preservatives.
Identification: Shake 1 mL with 10 mL of water containing 1 drop of 2 N sulfuric acid, and add 2 mL of ether: the subsequent addition of a drop of potassium dichromate produces an evanescent blue color in the water layer which upon agitation and standing passes into the ether layer.
Acidity: To 25 mL add phenolphthalein, and titrate with 0.10 N sodium hydroxide: not more than 2.5 mL is required for neutralization.
Barium: To 10 mL add two drops of 2 N sulfuric acid: no turbidity or precipitate is produced within 10 minutes.
Heavy metals: Dilute 4 mL, previously shaken, with 20 mL of water, add 2 mL of 6 N ammonium hydroxide, and gently boil the solution until the volume is reduced to about 5 mL Dilute with water to 25 mL: the limit is 5 ppm.
Limit of nonvolatile residue: Evaporate 20 mL, previously shaken, on a steam bath to dryness, and dry the residue at 105C for 1 hour: the weight of the residue does not exceed 30 mg.
Limit of preservative: Extract 100 mL of well-mixed Topical Solution in a separator with a mixture of 3 volumes of chloroform and 2 volumes of ether, using 50 mL, 25 mL, and 25 mL, respectively. Evaporate the combined extracts at room temperature in a tared glass dish to dryness, and dry over silica gel for 2 hours: the residue, if any, weighs not more than 50 mg (0.05%).
Hydrogen Peroxide FCC Food Grade Specifications
H2O2 --- Formula weight 34.01 --- CAS: 7722-84-1
DESCRIPTION
Hydrogen Peroxide occurs as a clear, colorless liquid. The grades of Hydrogen Peroxide suitable for food use usually have a concentration between 30% and 50%. It is miscible with water.
Note: Although Hydrogen Peroxide undergoes exothermic decomposition in the presence of dirt and other foreign materials, it is safe and stable under recommended conditions of handling and storage. Information on safe handling and use may be obtained from the supplier.
Function: Bleaching, oxidizing agent; starch modifier; antimicrobial agent.
REQUIREMENTS
Identification: Shake 1 mL of sample with 10 mL of water containing 1 drop of 2 N sulfuric acid, and add 2 mL of ether. The subsequent addition of a drop of potassium dichromate produces an evanescent blue color in the water layer that upon agitation and standing passes into the ether layer.
Assay: Not less than the labeled concentration or within the range stated on the label.
Acidity: (as H2SO4) Not more than 0.03%.
Iron: Not more than 0.5 mg/kg.
Lead: Not more than 4 mg/kg.
Phosphate: Not more than 0.005%.
Residue on Evaporation: Not more than 0.006%.
Tin: Not more than 10 mg/kg.
