Like, it just goes on your skin and you wash it off. Is there something special in the soap that attacks bacteria specifically?
In: 0
Soap molecules have an end that sticks to water (hydrophilic) and an end that sticks to oils (hydrophobic). A bacteria’s cell membrane, which is basically its skin, is made up of molecules with a very similar structure. Due to this similarity soap molecules can mix into the bacteria’s cell membrane, which breaks it open and kills the bacteria.
