Bentonite is a naturally occurring hydrated aluminium silicate; a highly absorbent clay which is composed of minerals including iron, silica and aluminium, it is usually formed from volcanic ash which has been aged by time and can vary in color from dark grey to greenish-grey.
Uses: Bentonite clay is used as a thickener, emulsion stabilizer and suspending agent for opaque products. It hydrates quickly and easily in water and gives structure to the water phase of your creams or liquid products and is particularly well suited to pigmented make-up such as BB creams, Liquid Foundation or tinted moisturizers.
