'Synthetic detergents are better than soaps'. Justify this statement​

Synthetic detergents can be used for washing purposes even when the water is hard, whereas soaps are not suitable for washing with hard water. This is because of the fact that synthetic detergents can lather with hard water. Hence, Synthetic detergents better than soaps.

Synthetic detergents work on both soft and hard water, while soap works only with soft water.
