The cleansing action of Soap: When a dirty cloth having oily spot is put in water containing dissolved soap, the oil is not dissolved in water. The soap molecules are salts of sodium and potassium of long-chain carboxylic acid. The acid end of soap is hydrophilic i.e. water-loving and gets dissolved in water and the carbon chain dissolves in oil. Soap molecules form the structure of a micelle in which one end of the soap molecule is attached to the oil droplet and the other end towards the water. The formation of soap micelles thus removes oil particles from the surface and the surface is cleaned.
