Synthetic detergents
1. Synthetic detergents are sodium alkyl sulphates or sodium alkyl benzene sulphonates with alkyl group having more than ten carbon atoms.
2. Synthetic detergents are prepared from the hydrocarbons of petroleum.
3. Calcium and magnesium salts of detergents are soluble in water and, therefore, no curdy white precipitates are obtained in hard water and hence, can be used even in hard water.
ADVERTISEMENTS:
4. They can be used in acidic medium as they are the salts of strong acids and are not decomposed in acidic medium.
5. The synthetic detergents are not biodegradable.
