Body wash, cleanse themselves with water should be enough. Why must use soap at once? Yes, so much cleaner with soap, can remove impurities. But, ever thought how the soap?
Soap-making material formed of various fatty acid chains. At each end of the chain there is an ion, usually sodium or potassium ions.

Soap molecule consists of two parts, which are hydrophilic and hydrophobic.Hydrophilic part is the part that likes water or polar. The hydrophobic part is the part that does not like water or nonpolar nature.
Polar impurities are usually soluble in water, so that this kind of dirt does not need to be cleaned with soap. Stools that are nonpolar, such as oil or fat will not go away if only cleaned using water. When soap mixed with water, the fatty acid chains will bind impurities, especially oily and fatty. Then, the ions contained in the fatty acid chain ends before going on duty to bring bond fatty acids and these impurities into the water.
Finally, dirt can be removed and taken away along with the water. It can not be done by ordinary water because water can not mix with the oil, so the dirt would not simply be lifted by the water.
Noteworthy: Most soap only works on fresh water. How to salt water as in sea water? Most soaps can not work on sea water because sea water contains too many minerals, especially sodium.
Sodium ions contained in the soap will be difficult to dissolve in water because the water already contains a lot of sodium ions. This soap will make it difficult to remove the dirt and take it away. However, soap made from potash generally still able to work in sea water because the levels of potassium in sea water is not as much sodium.
