The present invention relates to antimicrobial, porous particles, especially porous, non-platelet-like SiO2 particles, comprising an organic, or inorganic antimicrobial compound, or composition, with the proviso that the porous particles are not porous SiOz flakes, wherein 0.70<z<2.0, especially 0.95<z<2.0, which provide enhanced (long term) antimicrobial efficacy. |
