Uses and Benefit A surfactant (Surface-Active Agent).
Advantages:
1.   Very effective as a bactericide.
2.   It will form gels, emulsify oil and lower the surface tension of water.  A lower surface tension allows the soap to come in contact with the greater surface area than with water alone.

Why it is better than ordinary Liquid Soap?

Disadvantages of ordinary soap:::
1.   When used in hard water, soap can produce a scum - calcium and magnesium salts present in hard water react with the soap to cause this to happen.  Soapless or synthetic detergents do not leave a residual film behind.
2.   Considerable rinsing is required to remove soap scum.
3.   Soap may produce a greasy build-up on the surface which can be slippery.
4.   More expensive than synthetic detergents.
