Green clay (Montmorillonite)
Montmorillonite is a type of refined clay, composed of hydrated aluminium silicate. It often has a natural color that is caused by the presence of trace amounts of minerals such as iron in the structure of the clay. It has similar properties to kaolin. The Food and Drug Administration (FDA) has approved Pyrophyllite as a color additive exempt from certification. Pyrophyllite is allowed to be used as a color in externally applied cosmetics and personal care products and drugs if it conforms to FDA specifications. It is not allowed to be used in products intended for the lips or the eye area. The Food and Drug Administration (FDA) has reviewed the safety of Calcium Silicate and Bentonite and determined that they are Generally Recognized as Safe (GRAS) for use as direct food additives (Calcium Silicate at up to 2% of weight of food). Aluminum Silicate is approved for use in polymers with incidental contact with food. The safety of Aluminum Silicate and Montmorillonite has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that the ingredients were safe as used in cosmetics and personal care products.
