Explain the following terms with suitable examples:
(i) Cationic detergents
(ii) Anionic detergents and
(iii) Non-ionic detergents
(i) Cationic detergents These are quarternary ammonic salts of amines with acetates, chlorides or bromide.
Example : Cetyltrimethyl ammonium bromide
(ii) Anionic detergents These detergents have large anionic part in their molecules. These are of two types:
(a) Sodium alkyl sulphates For example, Sodium lauryl suphate CH3(CH2)10CH2OSO3–Na+.
(b) Sodium alkyl benzene sulphonates For example, sodium dodecyl benzene sulphona
(iii) Non-ionic detergents These are esters of high molecular mass alcohols with fatty acids. For example, Plyethylene glycol stearate.
