Which term correctly describes surfactants that remain nonionic?

• A. Anionic
• B. Cationic
• C. Nonionic
• D. Amphoteric

Answer: (C)

Surfactants are classified by their electrical charge in solution. Those that do not ionize and stay neutral in water are described as nonionic. Anionic surfactants carry a negative charge, cationic carry a positive charge, and amphoteric can carry either depending on the pH. Nonionic surfactants have uncharged head groups, which is why they don’t form ions in solution. This neutral behavior often makes them less sensitive to water hardness and pH and can lead to milder interactions with skin. So, the term that correctly describes surfactants that remain nonionic is nonionic.
