Question

Baby shampoo contains which of the following surfactants as detergent?

• A. \( \text{Sodium lauryl sulphate} \)
• B. \( \text{Cationic surfactant} \)
• C. \( \text{Amphoteric imidazole derivatives (Miranda)} \)
• D. \( \text{Alkyl sulfonates} \)

Hint:

Baby shampoos use amphoteric surfactants to minimize irritation while effectively removing dirt and oil.

Answer 1

The Correct Option is C

Amphoteric imidazole derivatives are mild surfactants used in baby shampoos to reduce irritation and dryness. Unlike harsh detergents like sodium lauryl sulfate, they maintain a gentle cleansing action while preserving scalp moisture. Their amphoteric nature allows them to act as both acidic and basic detergents depending on pH conditions.
