Sodium Hexametaphosphate
Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are all sodium polyphosphates made of repeating units of NaPO3. Sodium Metaphosphate generally refers to a long chain of NaPO3 units that is not soluble in water, which is why it is sometimes called insoluble metaphosphate. Sodium Trimetaphosphate has three NaPO3 units, and Sodium Hexametaphosphate has six NaPO3 units. Both the Trimetaphosphate and the Hexametaphosphate are soluble in water. In cosmetics and personal care products, Sodium Metaphosphate, Sodium Trimetaphosphate and Sodium Hexametaphosphate are used in the formulation of makeup foundations, mascara, bath products, and moisturizing and skin care products.
