What are biodegradable and non- biodegradable detergents ? What are the consquences of using latter class of detergents ?

Explanation

Biodegradable detergents are those which are decomposed by micro-organisms like bacteria into harmless products. Detergents having linear alkyl chains are biodegradable .
E.g : Sodium laurly sulphate , sodium -4(1-dodecyl) benzene sulphonate .
Non-biodegradable detergents are those which are non decomposed by microorganism. Detergents with branched chains are non-biodegradable .
E.g: Sodium-4-(1,3,5,7- tetramethyloctyl) benzene sulphonate etc .
Slow degradation of non-biodegradable detergents leads to their accumulation . Effluents containing such detergents reach the rivers , ponds , etc. These persist in water even after sewage treatment and cause foaming in rivers , pond and streams and their water gets polluted . Biodegradable detergents do not cause water pollution .
