Why Does Hydrogen Peroxide Foam On Our Wounds? - Science ABC

Hydrogen peroxide reacts with an enzyme present inside the body that decomposes while releasing foam. However, it is also stored inside cells, in such a manner that it does not destroy the cell itself.

Have you ever read the ingredients listed on a bottle of household disinfectant, chlorine-free beach, or a packet of hair dye? You’ll find something common to all three – Hydrogen Peroxide.

Hydrogen peroxide has been used since 1920s as a mild antiseptic to clean some injuries and abrasions. When dabbed over a wound or cut, it leads to the formation of a white sizzling foam that covers the injury, providing protection from infection thanks to its anti-bacterial properties.

Have you ever wondered why hydrogen peroxide bubbles on our wounds when it is applied as an antiseptic, yet it doesn’t have the same reaction on a table or our hair when used as a disinfectant or hair dye? If this has ever tickled your curiosity, you’ve come to the right place.
