Benzoyl peroxide is usually prepared by treating hydrogen peroxide with benzoyl chloride under alkaline conditions. 2 C 6 H 5 COCl + H 2 O 2 + 2 NaOH → (C 6 H 5 CO) 2 O 2 + 2 NaCl + 2 H 2 O. The oxygen–oxygen bond in peroxides is weak. Thus, benzoyl peroxide readily undergoes homolysis (symmetrical fission), forming free radicals: (C 6 H 5 ...
The peroxide value is defined as the amount of peroxide oxygen per 1 kilogram of fat or oil. Traditionally this was expressed in units of milliequivalents, although in SI units the appropriate option would be in millimoles per kilogram (N.B. 1 milliequivalents = 0.5 millimole; because 1 mEq of O2 =1 mmol/2 of O2 =0.5 mmol of O2, where 2 is valence).
Benzoyl peroxide and hydrogen peroxide are used as bleaching and "maturing" agents for treating flour to make its grain release gluten more easily; the alternative is letting the flour slowly oxidize by air, which is too slow for the industrialized era. Benzoyl peroxide is an effective topical medication for treating most forms of acne.
Erythromycin/benzoyl peroxide, sold under the brand name Benzamycin, is a topical gel containing of 5% benzoyl peroxide and 3% erythromycin primarily used to treat acne. [1] Erythromycin/benzoyl peroxide is a prescription medication.
It contains clindamycin, as the phosphate, a lincosamide antibacterial; adapalene, a synthetic retinoid; and benzoyl peroxide, an oxidizing agent. [2] It is applied to the skin . [ 2 ]
Cobalt salts are the most common type of promoter used. Common radical initiators used are organic peroxides such as benzoyl peroxide or methyl ethyl ketone peroxide. [8] Polyester resins are thermosetting and, as with other resins, cure exothermically. The use of excessive initiator especially with a catalyst present can, therefore, cause ...
A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution. [1]
