ABSTRACT:
The application relates to a preferably golden color luster pigment based on lamellar substrates, in particular mica, which have been coated with metal oxides, the metal oxide layer containing both titanium and iron and the pigment containing mainly a pseudobrookite layer formed by simultaneous precipitation of the metal oxides. This golden color luster pigment is suitable for cosmetic articles because of its physiological acceptability and is particularly suitable for silicate melts because of its resistance to heat and chemicals.
