Which option is NOT a function of kaolin?

• A. Absorbent property
• B. Astringent and toning effect on the skin
• C. Gentle cleansing
• D. Oil absorption

Answer: (B)

Kaolin is a mild, absorbent clay used in skincare to help remove surface oils and impurities without stripping the skin. Its main functions are to absorb excess oil, provide gentle cleansing by drawing dirt to the surface, and help keep the skin feeling clean without harshness. It also effectively absorbs oil, helping to control shine.

What it does not do is create an astringent or toning effect. Astringents tighten the skin and pores and are often achieved with ingredients like alcohol or tannins. Kaolin doesn’t cause that contracting or toning action, so that particular effect isn’t a function of kaolin.
