Hair shampoos/conditioners are made up of cationic detergents. These are quaternary ammonium salts of amines with chlorides, bromides, or acetates, e.g., cetyltrimethylammonium bromide.
(ii)
Anionic detergents are used in toothpaste e.g. sodium dodecylbenzenesulphonate. It can be prepared as follows:
(iii) C17H35COO−Na++Na2CO3+Rosin
Laundry soaps contain fillers like Sodium Rosinate, Sodium silicate, Borax, and Sodium carbonate. Sodium rosinate makes the soap lather well.

(iv) CH3(CH2)16COO(CH2CH2O)nCH2CH2OH
Dishwashing powders are non-ionic detergents, and it can be prepared as:
CH3(CH2)16COOH+HO(CH2CH2O)nCH2CH2OH−H2O−−−−→CH3(CH2)16COO(CH2CH2O)nCH2CH2OH
