Use of an organofluorine hydrocarbon compound as a binder for cosmetic powder compositions, and composition containing said compound

A cosmetic powder composition constituted by a particulate phase comprising pigments and/or fillers and a greasy phase, wherein the greasy phase represents 1.01% to 35% by weight of the total composition weight and comprises 0.1% to 15% by weight of at least one organofluorine hydrocarbon compound having a ratio of hydrogen atoms bonded to carbon atoms substituted by fluorine atoms ranging from 0.5% to 95%, and 98.99% to 65% by weight of a particulate phase free of fluorine compound comprising pigments and/or fillers, the organofluorine hydrocarbon compound having formula (I):

• (R.sub.F).sub.x --(A).sub.y --(R.sub.H).sub.z (I)
• where:
• x represents 1, 2 or 3, y represents 0 or 1, and z represents 0, 1, 2 or 3, provided that y and z are not simultaneously zero and that when z is 0, x is 2 or 3;
• R.sub.F represents an aliphatic or aromatic, saturated or unsaturated, linear, branched or cyclic fluorinated radical, in which the chain may be functionalized and/or interrupted by a divalent oxygen or sulfur atom, or a trivalent nitrogen atom and/or substituted by hydrogen atoms or halogen atoms other than fluorine atoms, provided that for any two carbon atoms of the backbone, no more than one of these substituents other than fluorine is present;
• R.sub.H represents an aliphatic or aromatic, saturated or unsaturated, linear, branched or cyclic hydrocarbon radical, in which the chain may be functionalized and/or interrupted by one or more divalent oxygen or sulfur atoms, or one or more trivalent nitrogen atoms;
• and
• A represents a di-, tri- or tetravalent radical selected from the group consisting of:
• ##STR9## and ethylenic unsaturations.
