Answer the following:

Why is detergent better than soap in cleaning action?

Soap is one of the most common cleansing agents but they are capable of cleaning dirt only in soft water, soap does not form lather with hard water and therefore cleansing action does not become effective but detergents can clean dirt in hard as well as soft water with same effectiveness because detergent forms lather with hard water along with soft water, hence detergent is better than soap in cleaning action.
