Bentonite Clay

INCI Name

Bentonite

Botanical Name

N/A

A naturally occurring mineral clay rich in montmorillonite, Bentonite is a high-performance absorbent used to mattify, clarify, and thicken formulations. It’s favored in masks, cleansers, and scrubs for oily or blemish-prone skin due to its strong oil-binding capacity and creamy slip when properly hydrated. Source cosmetic-grade, purified material with documented heavy-metal testing, and avoid inhalation of powders during manufacturing for best-practice safety.
