While I have a different opinion from a comment above that oil, soap, milk cannot be converted to a brand. Marico rules with parachute, dove have some premium soap, Amway have premium bodywash, bath and bodyworks, organic companies sell soaps and washes at premium and lastly pride of cow milk is almost double the cost of taste of India. Long story short, if intent, competence, innovation and commitment is there, any commodity can be turned to a brand. To protect that brand would need constant innovation and value addition.
For modi natural, it maybe able to make good brands but the return to investors would depend on corporate governance and ethics. Ruchi Soya also has market leader in soya products but investors were battered…I thing positive changes in corporate governance is what should be also watched at, if that is possible
