Overview

Montmorillonite is a clay ingredient that is part of the smectite clay group. This ingredient appears dull and earthy, but it does come in a range of different colors, including white, pink, blue and green.

Montmorillonite has many functions, including the ability to absorb water. This action causes it to swell, which also makes it a good viscosity controlling agent and emulsion stabilizer.

In addition, this ingredient can serve as an opacifying agent, which is useful in skincare products requiring coverage, such as a foundation. Due to this opacifying ability, montmorillonite also protects the skin against certain lights.
