							Soaps are sodium or potassium salts of long chain carboxylic acid or fatty acids which shows cleansing mechanism in water by micelle formation.


The non polar head gets dissolved in oil or dirt stain on the cloth and the polar end dissolves in water and they form a cluster like structure called soap micelle. On agitation oil and dirt is removed from the cloth. This is the cleansing mechanism of the Soap.
