R is hydrophobic tail and COO– Hydrophilic head. RCOO– ions present at the surface with COO– group inside and R group outside.
Increasing concentration to critical micelle concentration anions are pulled inside the bulk and Form a spherical shape of hydrocarbon chain pointing towards the centre and COO– pointing outside this are called as micelle.
