Cosmetic composition in the form of a compact, impact-resistant powder

A pulverulent composition (C1) in the form of a powder comprising, per 100% of its mass:

• i) from 84.3% to 95.8% by mass of at least one filling agent (FA)
• ii) from 4% to 15% by mass of at least one colored pigment (CP)
• iii) from 0.2% to 0.7% by mass of at least one polymer of crosslinked anionic polyelectrolyte type (P) which comprises, per 100 mol %, from 65 mol % to 95 mol % of monomer units derived from partially or totally salified 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid, from 4.8 mol % to 25 mol % of monomer units derived from at least one neutral monomer chosen from the elements of the group consisting of 2-hydroxyethyl acrylate, N,N-dialkylacrylamides in which each of the alkyl groups comprises between one and four carbon atoms, and from 0.1 mol % to 5 mol % of monomer units derived from at least one monomer of formula (I):
• in which R represents a linear or branched alkyl radical comprising from eight to twenty carbon atoms and n represents a number of greater than or equal to zero and of less than or equal to twenty, and from 0.1 mol % to 5 mol % of monomer units derived from at least one diethylenic or polyethylenic crosslinking monomer;
• wherein the at least one polymer of crosslinked anionic polyelectrolyte type (P) is (i) a terpolymer of ammonium 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonate, N,N-dimethylacrylamide and tetraethoxylated lauryl methacrylate, crosslinked with trimethylolpropane triacrylate;
• or (ii) a crosslinked polyelectrolyte of ammonium 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonate, of 2-hydroxyethyl acrylate, of stearyl methacrylate and of lauryl methacrylate, crosslinked with trimethylolpropane triacrylate.
