Based on the context, eagerly I well come feed back topics . The purpose is to learn from each other . I might as well put questions , specially , in certain Science Matters writings as enhancement of thinking .

Soap

-is a mixture of the sodium salts of long chain fatty acids such as palmitic acid , C15H31CO2H , stearic acid ,C17H35CO2H and oleic acid , C17H33CO2H .These acids occur as esters of the tri-hydroxy alcohol , glycerol , in animal fat and in vegetable oils .

Soap is made by boiling fat with NaOH solution and the reaction is known as hydrolysis or saponification . ( Complete chemical reaction can only be displayed with the help of ChemDraw software package .)

Detergent

In the sense of being a cleaning agent , soap is detergent .However , the term is commonly used in reference to synthetic cleaning agents such as alkyl benzene sulphonates .

Comparison

As with soap , the ionic end dissolves preferentially in water , and the hydrocarbon chain dissolves preferentially in oils and greases .Why ?

The synthetic detergents are more soluble than soap and , because their magnesium ( Mg ++ ) and Calcium ( Ca ++ ) are soluble , more effective in hard water . The alkyl chain can be of variable length and degree of branching .Detergents with branched alkyl chains are more resistant to breakdown by bacteria , and are therefore called non-biodegradable , the core point of the whole discussion .
