Green Clay (Montmorillonite) – Cosmetic Uses in Absorbent and Cleansing Products
What Is Green Clay (Montmorillonite)?
Montmorillonite is a refined clay composed of hydrated aluminium silicate. Its characteristic green colour can result from trace amounts of minerals such as iron within the clay structure.
Montmorillonite has properties similar to kaolin and is widely used in cosmetic and personal care formulations.
Cosmetic Uses of Montmorillonite
Montmorillonite is primarily used as an absorbent, bulking and viscosity-controlling ingredient. It can also contribute to the stability of emulsions and other cosmetic formulations.
It is particularly suitable for products where clay's absorbent properties and ability to modify formulation texture are desirable, including masks, cleansing products and other skin care preparations.
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed the safety of montmorillonite and related ingredients and concluded that they are safe as used in cosmetics and personal care products.
