    We need soap for various purposes. One of the most important usage of soap is that it helps washing out harmful germs that stick on the other surface of our hand due to the natural oils.

    Recently, considering the increased usage of soap due to COVID-19 pandemic, the manufacturers to have started producing soaps with different scent, different features.

    Apart form this, the soap is also used in form of detergent to clean cloth material.
