Soaps & Detergents- are the sodium salts of higher molecular masses fatty acids & aromatic acids. • Types of detergents-cationic detergent –the dtergent in which the large hydrocarbon part is cation • Example: cetyltrimethylammoniumbromide. • Anionic detergent: the detergent in which the large hydrocarbon part is anionic • Example:Sodiumdodecylbenzenesulphonate, • sodiumlaurylsulphate.
Nonionicdetergent:Thedtergent having no cationic and anionic part. • Example:Polyethyleneglycolsteriate . • Difference between soaps &detergent • 1.Soaps are biodegradable Detergents are nonbiodegradable. • 2.Soap form lather with soft water while detergents form lather with soft &hard water.
