Abstract: The present invention relates to intensely coloured and light-stable effect pigments based on transparent, undoped SiO2 flakes, which are distinguished by the fact that they are covered with an iron-oxide layer having a thickness of 30-150 nm, and all SiO2 flakes have an identical thickness, and the thickness of the SiO2 flakes is 250-400 nm, and to the use thereof in pigment mixtures, in cosmetic formulations and for colouring foods and pharmaceutical products.

Abstract: Cosmetic or dermatological stick preparations, which are finely disperse systems of the water-in-oil type, comprising a) an oil phase which ?comprises from 10 to 70% by weight, based on the weight of the fatty phase, of fatty and/or wax components which melt above a temperature of 40° C., b) a water phase, c) at least one modified phyllosilicate which exhibits both hydrophilic and also lipophilic properties, which thus has amphiphilic character and positions itself at the water/oil interface, and d) at most 0.5% by weight of one or more emulsifiers and method for their preparation.
