过氧化苯甲酰的用途

大多数过氧化苯甲酰被用作引发聚合反应的自由基引发剂。其他主要应用包括其防腐和漂白性能。
痤疮治疗
Benzoyl peroxide for acne treatment is typically applied to the affected areas in gel or cream form, in concentrations of 2.5% increasing through the usually effective 5% to up to 10%. Research suggests that 5 and 10% concentrations are not significantly more effective than 2.5%, and 2.5% is usually better tolerated, though the majority of major studies comparing it to other treatments use the higher concentrations. It commonly causes initial dryness and sometimes irritation, although the skin develops tolerance after a week or so. A small percentage of people are much more sensitive to it and liable to suffer burning, itching, peeling and possibly swelling. It is sensible to apply the lowest concentration and build up as appropriate. Once tolerance is achieved, increasing the quantity or concentration and gaining tolerance at a higher level may give better subsequent acne clearance. Benzoyl peroxide works as a peeling agent, increasing skin turnover and clearing pores, thus reducing the bacterial count there as well as directly as an antimicrobial.[citation needed] It is often combined with salicylic acid, sulfur, erythromycin or clindamycin (antibiotics), giving rise to a combination drug, in benzoyl peroxide/clindamycin. It can also be given with adapalene (a synthetic retinoid) in adapalene/benzoyl peroxide, a unique formulation considering most retinoids are deactivated by peroxides and acids.
其他用途
过氧化苯甲酰的其他常见用途包括染发,以及作为牙齿美白系统中的活性成分。它也可用于面粉的制备中,并可用作聚酯热固性树脂的引发剂和催化剂(作为危害更大的甲基乙基酮过氧化物的替代品)。
In the U.S., the typical concentration for benzoyl peroxide is 2.5% to 10% for both prescription and over-the-counter drug preparations that are used in treatment for acne. Higher concentrations are used for hair bleach and teeth whitening. Benzoyl peroxide, like most peroxides, is a powerful bleaching agent. Contact with fabrics or hair can cause permanent color dampening almost immediately. Even secondary contact can cause bleaching. For example, contact with a towel that has been used to wash off benzoyl peroxide-containing hygiene products.[citation needed] In the paint industry, Benzoyl peroxide is used as hardener in order to start the polymerization process in resins for instance PMMA resins can be polymerized with DiBenzoyl Peroxide.
