Cosmetic makeup composition and / or caring for keratin materials, and makeup process

The present invention relates to a composition comprising, in a physiologically acceptable medium: a) a siloxane resin comprising at least 80 mole% of units (i) (R 'SiO) and (ii) (SiO) in which • R 'independently represents an alkyl group having 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group, with the proviso that at least 95 mol% of the R' groups are alkyl groups, • a and b have values ​​strictly greater than 0; • and the ratio a / b is between 0.5 and 1.5, and b) a propyl silsesquioxane resin comprising at least 80 mole% of units (R "SiO) wherein R" independently represents an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group, with the proviso that at least 80 mol% of the R "groups are propyl groups, the weight ratio between the resins a) and b ) being between 1/99 and 99/1, resins a) and b) being not bonded with each other by covalent bonds, and the number of M units of the final mixture being strictly less than the number of units (T + Q), c) at least one additional ingredient chosen from pasty compounds of non-animal origin, thickeners or rheological agents fatty-phase gelling agents except dimethicone crosspolymers, waxes in except candelilla wax, ozokerite and silicone waxes, gelling agents hydrophilic, fillers, film forming polymers, ionic surfactants with the exception of lauryl ether sulfate, fibers, and mixtures thereof.
