Benzoyl Peroxide is an organic compound with structural formula C₅H₅−C(=O)O−)₂, abbreviated as BzO₂. It is a peroxide with a keratolytic, comedolytic, antibacterial, irritant, and anti-inflammatory action. It decomposes to release oxygen which is lethal to the bacteria Propionibacterium acnes. Benzoyl Peroxide appears as odourless white granules or powder. It is sparingly soluble in water. It enhances the turnover rate of epithelial cells, through peeling the skin. The Benzoyl Peroxide is an oxidizer, which is generally utilised in the generation of polymers.
The chemical structure of a molecule in the Benzoyl Peroxide involves the arrangement of the atoms and the chemical bonds that holds all the atoms collectively. The Benzoyl Peroxide molecule comprises 29 bonds. There are 14 multiple bonds, 5 rotatable bonds, 19 non-H bonds, 2 double bonds, 12 aromatic bonds, and 2 six-membered rings. In the structure of Benzoyl Peroxide, the carbon atoms are intended to be placed at the edges, and the hydrogen atoms attached to carbon atoms are not indicated. Each carbon atom is estimated to be associated with sufficient hydrogen atoms to render the carbon atom with 4 bonds.

Q1. How to Use Benzoyl Peroxide Cream or Gel?
Answer: Benzoyl Peroxide products are available as cleansers, foam, or lotion. Some products require a prescription, and some can be purchased without a prescription. To use the benzoyl peroxide cream, we need to wet the area of treatment, then take a small amount of the lotion in our hands and smoothly massage in the affected area. We should keep the liquid on our skin for 1 or 2 minutes and then rinse off the skin thoroughly with water and gently pat the area dry with a towel.
Q2. What are the Uses of Benzoyl Peroxide?
Answer: Benzoyl Peroxide is used for skin treatment. We should always wash our hands before and after using Benzoyl Peroxide. If the skin starts peeling off or gets dry, Benzoyl Peroxide should be used as it helps to treat the dry skin. Benzoyl Peroxide can also discolour or bleach our hair, towels, clothes, and bedding. It should be kept away from coloured fabrics and hair. With the help of the Benzoyl peroxide, the polymerization process of resins can also be started. Benzoyl Peroxide can also be used as a bleaching agent in bread and cheese.
