Detergents are amphipathic molecules, meaning they contain both a nonpolar tail having aliphatic or aromatic character and a polar head.Ionic character of the polar head group forms the basis for broad classification of detergents they may be ionic charged, either anionic or cationic, nonionic uncharged, or zwitterionic having both positively and negatively charged groups but with a.
