Detergents are classified as cationic (acetates/chlorides of quaternary ammonium salts), anionic (long-chain sulphonate/sulphate salts), and non-ionic (esters from polyethylene glycol and stearic-type acids). Which of the following is the non-ionic detergent used in liquid dishwashing detergents?

1. CH3-(CH2)15-N+(CH3)3 Br-
2. CH3-C6H4-SO3- Na+
3. CH3(CH2)10CH2OSO3- Na+
4. C9H19-C6H4-O-(CH2-CH2-O)5-CH2-CH2OH

Correct answer: C9H19-C6H4-O-(CH2-CH2-O)5-CH2-CH2OH

Solution

The polyethylene-glycol-based ether with no charged head group is the non-ionic detergent commonly used in liquid dishwashing detergents.
