Benzoyl peroxide is a chemical compound (specifically, an organic peroxide) with structural formula (C6H5−C(=O)O−)2, often abbreviated as (BzO)2. In terms of its structure, the molecule can be described as two benzoyl (C6H5−C(=O)−, Bz) groups connected by a peroxide (−O−O−). It is a white granular solid with a faint odour of benzaldehyde, poorly soluble in water but soluble in acetone, ethanol, and many other organic solvents. Benzoyl peroxide is an oxidizer, which is principally used in the production of polymers.Benzoyl peroxide with 25% water is primarily used as a radical initiator in polymerization processes and as an antiseptic and bleaching agent. It’s also found in acne treatments, hair and teeth bleaching products, and as a hardener in polyester resins.
