What this ingredient generally does

Montmorillonite is a clay-based mineral that does several jobs: it adjusts thickness, absorbs, and keeps the mix from separating. In practice it helps hold the water and oil parts together and controls how the product flows. It can also act as a mild scrubbing particle and a light stabilizer that helps protect the formula from light.
