Pearlescent titanium dioxide flakes

Pearlescent pigments contain small flakes or platelets of the mineral mica that are additionally coated with a very thin layer of titanium dioxide. The simultaneous reflection of light from many layers of small platelets creates an impression of luster and sheen. By varying the thickness of the coating on the surface of the mica particles, pigment manufacturers can achieve a range of colors for the pearlescent effect. 

These products exist in different forms, such as compact powders, which are the most commonly used. They are conditioned in cases with one shade only or a selection of several. The coloured product is apphed with a flexible brush or foam applicator. The raw materials are principally pearlescent agents dispersed in a powder base composed of talc (which give softness and easy ghde), kaolin, titanium dioxide or calcium carbonate. Lipophilic binders are necessary to ensure compacting and the dispersion of pigments. They help to avoid flaking or the formation of dust and give a soft texture. Likewise, volatile sihcones help to avoid the chalky effect owed to powders.
