detergents are non biodegradable while soaps are biodegradable comment?

Soaps are formed by the reaction of alkaline (lye) and fats and oils.Tes are the sodium salts of fats and oils. Fats and oils can easily be broken down into simple molecules by  microbes and hence soaps are biodegradable.

Detergents are synthetic compounds generally ammonium or sulfate salts of long chain carboxylic acids.These sythatic compounds can not be broken down into simple molecules by microbes and hence soaps are non biodegradable
