Question

Which of the following is an example of a non-ionic detergents?

Options

• Sodium lauryl sulphate

• Cetyltrimethyl ammonium bromide

• Polyethylene glycol ether

• Sodium stearate

Answer 1

Polyethylene glycol ether

Explanation:

Non-ionic detergents do not carry any electrical charge on their hydrophilic head. Instead of an ionic group, they use –OH (hydroxyl) or –O– (ether) groups from polyethylene glycol (PEG) chains to attract water through hydrogen bonding. This makes them very mild, gentle, and stable in both acidic and alkaline conditions.
