उत्तर
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.
