C14H10O4 — 242.2 — 94-36-0
Action and use: Used topically in the treatment of acne.
DEFINITION:
Content:
dibenzoyl peroxide : 70.0 per cent to 77.0 per cent;
water: minimum 20.0 per cent.
Content:
dibenzoyl peroxide : 70.0 per cent to 77.0 per cent;
water: minimum 20.0 per cent.
CHARACTERS:
Appearance: White or almost white, amorphous or granular powder.
Solubility: Practically insoluble in water, soluble in acetone, soluble in methylene chloride with the separation of water, slightly soluble in ethanol (96 per cent).
It loses water rapidly on exposure to air with a risk of explosion.
Mix the entire sample thoroughly before carrying out the following tests.

IDENTIFICATION:
First identification B.
Second identification A, C, D.
A. Ultraviolet and visible absorption spectrophotometry.
B. Infrared absorption spectrophotometry. Comparison Ph. Eur. reference spectrum of hydrous benzoyl peroxide.
C. Dissolve about 25 mg in 2 mL of acetone. Add 1 mL of a 10 g/L solution of diethylphenylenediamine sulfate and mix. A red colour develops which quickly darkens and becomes dark violet within 5 min.
D. To 1 g add 5 mL of ethanol (96 per cent), 5 mL of dilute sodium hydroxide solution and 10 mL of water. Boil the mixture under reflux for 20 min. Cool. The solution gives reaction of benzoates.

TESTS:
Acidity: Dissolve a quantity of the substance to be examined containing the equivalent of 1.0 g of dibenzoyl peroxide in 25 mL of acetone, add 75 mL of water and filter. Wash the residue with two quantities, each of 10 mL, of water. Combine the filtrate and the washings and add 0.25 mL of phenolphthalein solution. Not more than 1.25 mL of 0.1 M sodium hydroxide is required to change the colour of the indicator. Carry out a blank test.
Related substances: To pass the test.
Chlorides: Maximum 0.4 per cent.
