Bentonite ek clay hai jo montmorillonite se bhara hota hai. Isko masks aur cleansers mein use karte hain taaki skin ke excess sebum, oils aur impurities ko absorb kar sake. Yeh skin ko clean aur fresh feel deta hai. Cosmetic formulations mein iska use thickening aur stabilizing agent ke taur par bhi hota hai, jisse products ka texture theek rahta hai.
