DESCRIPTION:

BRIEF SUMMARY
This application is a 371 of PCT/FR93/00099 filed Jan. 29, 1993.
The subject of the present invention is a cosmetic make-up composition, the latter containing a transparent titanium oxide and silicon oxide pigment.
Make-up products such as loose or compacted powders, foundations, blushers, eye shadows, lipsticks as well as nail varnishes contain, in variable proportions, pigments intended to confer on these products some color as well as optionally inorganic fillers intended especially to provide a good covering power.
In order to obtain a covering effect, titanium dioxide may be used as opacifying white pigment. However its use renders the spreading of the compositions on the skin difficult and brings about its whitening. If it is desired, in addition, to obtain a pearlescent effect, a pearlescent pigment such as titanium oxide-coated mica (mica-titanium) or bismuth oxychloride should be added. However, the use of mica-titanium can have disadvantages linked to poor spreading and to the lack of smoothness.
Furthermore, when it is desired to enhance the pearlescent effect, it is possible to increase the amount of mother-of-pearl but in this case, problems of cohesion are encountered which necessitate increasing the amount of binder such that it causes inconvenience during application. Finally, it should be noted that mother-of-pearls are particularly fragile particles which, when they are ground, lose their pearlescent effect.
If it is desired to confer a pronounced colored effect, it is necessary to use colored organic or inorganic pigments, but increasing the amount of pigments causes, on the one hand, a color saturation and, on the other hand, problems of homogeneity of the pigments in the formula.
If it is desired to enhance the colored effect of the pigments, iron oxide for example may be incorporated, as described in Patent Application JP 61-295234, into the lamellar titanium dioxide coating layer.
After various studies with a view to overcome the abovementioned disadvantages, it was observed, surprisingly, that by using, as pearling agent in a cosmetic make-up composition, a transparent pigment consisting of at least 60% by weight of titanium oxide and at most 10% by weight of silicon oxide, it was possible to obtain excellent cosmetic properties, these transparent pigments conferring at the same time a satisfactory pearliness and an appropriate level of coverage, a high spreadability and a smoothness which is not observed with conventional pearly pigments. A more homogeneous film is also obtained in which the transparent pigments are well distributed.
These transparent pigments, because of their shiny, pearly and colored iridescent effect, and by virtue of their cosmetic properties, are particularly suitable for a cosmetic use without the disadvantages of the pigments of the prior state of the art being encountered. Furthermore, these transparent pigments are less fragile than the mother-of-pearls, which makes it possible to grind them without losing their pearlescent effect.
The subject of the present invention is therefore a cosmetic make-up composition containing, in a suitable cosmetic carrier, a transparent pigment consisting of at least 60% by weight of titanium oxide in lamellar form and at most 10% by weight of silicon oxide, the mean size of the pigments being between 1 and 300 .mu.m and the thickness between 0.001 to 0.3 .mu.m.
Preferably, the transparent pigments consist of at least 90% by weight of titanium oxide, in lamellar form, and at most 6% by weight of silicon oxide.
According to a preferred embodiment of the invention, the mean size of the transparent pigments is between 5 and 50 .mu.m, and the thickness between 0.01 and 0.2 .mu.m and more particularly between 0.1 and 0.2 .mu.m.
The transparent pigments of the cosmetic composition according to the invention are described in European Patent Application EP 377 326 to which reference is made herein. These transparent pigments are, according to this application, obtained by dissolution of a major part of the silicon oxide of silicon
