Question
Explain their cleansing action?
✓
Answer
The cleansing action of both soaps and detergents results from their ability to lower the surface tension of water, to emulsify oil or grease and to hold them in a suspension in water. This ability is due to the structure of soaps and detergents. In water, a sodium soap dissolves to form soap anions and sodium cations.
