Abstract: There is described a process for the preparation of a cosmetic product with powders (1, 20, 57) having different features, specifically being multicoloured, carried out by the steps of precipitating cosmetic powders, compressing, forming cavities (9, 26, 49), and exciding excesses. It is possible to obtain a cosmetic product (1, 20, 57) partitioned into coloured sectors (2, 3, 21, 22, 41, 52) which may even be very small and form detailed patterns. Such an invention allows to reduce working costs and achieve high levels in the quality of the cosmetics from the aesthetical point of view. (FIG. 1).
