SOAP

Soap is sodium salt or potassium salt of long-chain fatty acid


general formula:

RCOONa^{+       or}         RCOOK⁺

R : containing 12 to 18 carbon atoms. it can be saturated or un saturated.

The history of soap manufacturing 

Early  soapmaker  disperse wood ashes in water, added animal fat to the solution,  then boil the mixture to make soap. modern day soap making uses vegetable oil in place of animal at and caustic alkali in place of wood ashes. Vegetable oil is a natural ester. When the vegetable oil is  boiled with caustic alkali, it is hydrolysed into soap which is actually a salt of fatty acid. the process is called saponification.
