Merck has introduced Colorona Precious Gold, a new effect pigment that exhibits natural gold-like effects. This golden lustre comes from the manufacturing process, with the advanced coating technology lending previously unachievable colour intensity. The controlled deposition of multiple layers of metal oxide onto a mica substrate level give the pigment hiding power and colour intensity. Merck says this makes the
pigment unique compared to other gold pigments. It is considered effective in a multitude of cosmetic applications, particularly eye, lip and nail products.
Merck offers Colorona Precious Gold with a particle size of 10 - 60mm and the pigment can be used in both low and high concentrations.
