CAS:94-36-0 Benzoyl Peroxide powder
Products Description
Benzoyl peroxide is a commonly used drug in topical treatments for acne. It has been formulated as products with either a single active ingredient, or with [erythromycin], [clindamycin], or [adapalene]. After administration, the peroxide bond is cleaved, allowing benzoyloxy radicals to nonspecifically interact with proteins. This treatment decreases keratin and sebum around follicles, as well as increasing turnover of epithelial cells.
