Surfactants in shampoo are classified by the electrical charge of their head group. Which charge class is the primary CLEANSING surfactant in most shampoos?
a.Cationic (positive)
b.Nonionic (no charge)
c.Anionic (negative)
d.Amphoteric (both charges)
Explanation
Anionic surfactants such as sodium lauryl sulfate carry a negative charge and produce strong lather and grease removal, so they are the main cleansing detergents. Cationic agents condition, amphoterics are mild, and nonionics are used as emulsifiers and solubilizers.
