Explain the cleansing action of soaps.

(N/A) micelle consists of a hydrophobic hydrocarbon-like central core. The cleansing action of soap is due to the fact that soap molecules form a micelle around the oil droplet in such a way that the hydrophobic part of the stearate ions is in the oil droplet and the hydrophilic part projects out of the grease droplet like bristles.
The polar groups can interact with water; the oil droplet surrounded by stearate ions is now pulled into the water and removed from the dirty surface. Thus,soap helps in the emulsification and washing away of oils and fats. The negatively charged sheath around the globules prevents them from coming together and forming aggregates.
