Benzoyl Peroxide (BPO) is a powerful organic peroxide utilized primarily as a radical initiator in polymer chemistry. Our Technical Grade product is typically supplied in a wetted form (75% Purity) to ensure safe handling and transport.
In the pharmaceutical sector, it is a leading acne treatment active, recognized for its potent antibacterial and keratolytic properties. It effectively oxygenates skin pores, neutralizing P. acnes bacteria while promoting cell turnover.
For industrial applications, BPO is indispensable in the curing of polyester resins and the bleaching of edible oils. It serves as a critical cross-linking agent for specialized rubber compounds and thermosetting plastics.
