Bentonite Clay - 5Kg Other Names: Montmorillonite Clay Description: 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 colour from dark grey to greenish-grey. Uses: Bentonite clay is used as a thickener, emulsion stabiliser 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 moisturisers. Use Levels: 0.5-3% Formulating Tips: Add to the water phase while stirring. Bentonite is heat stable so you can heat the water to decrease hydration time. Continue mixing until a smooth thickened water phase is formed with no lumps. The clay should be hydrated in pure water with no additives.
