_____ are cleaners containing surfactants that cause the product to foam and rinse off easily.

• A. Cream cleansers
• B. Foaming cleansers
• C. Gel cleansers
• D. Oil cleansers

Answer: (B)

Surfactants give cleansers their ability to foam and to rinse off easily. These molecules have a water-loving end and a oil-loving end, so when they’re mixed with water and agitated, they create a lather that traps dirt and oil. That foam makes it easier to lift contaminants from the skin and then rinse them away with water, leaving the skin clean.

Foaming cleansers are designed to produce that abundant foam because of their surfactants, which is why they’re the best match for the description. Cream cleansers are typically richer and less foamy, often formulated with emollients, so they don’t foam as much. Gel cleansers can be foaming, but the statement emphasizes cleaners that foam and rinse off easily, which aligns with foaming cleansers. Oil cleansers rely on dissolving oils rather than foaming, so they don’t fit the description of producing foam.
