The invention provides an inorganic particle dispersion comprising a novel block copolymer capable of improving dispersibility of inorganic particles, particularly an inorganic particle dispersion for a cosmetic. n The inorganic particle dispersion, particularly the inorganic particle dispersion for a cosmetic of the present invention comprises a dispersion medium, an inorganic particle dispersed in the dispersion medium, and a block copolymer comprising a hydrophobic segment and a hydrophilic segment, wherein the hydrophobic segment comprises a monomer unit composed of at least one monomer selected from the following Formula 1 and Formula 2, wherein at least a portion of the hydrophilic segment is adsorbed on the inorganic particle, and the hydrophobic segment is oriented outwardly relative to the inorganic particle: n n n n n n n n n n n n where R 1 is hydrogen or a methyl group, R 2 is hydrogen or fluorine, m is an integer of 0 to 6, and n is an integer of 1 to 15, n n n n n n n n n n n n n n n n where R 1 is hydrogen or a methyl group, R 3 and R 4 are each independently an alkyl group having 1 to 6 carbon atoms, m is an integer of 1 to 6, and p is an integer of 5 to 70. |
