3                                                (a) the industrial chemical is an industrial chemical that:                                                                                                                                                                                                                medium to high risk
                                                 (i) is a solid, or is in a dispersion, at the time of introduction; and
                                                 (ii) consists of solid particles, in an unbound state or as an aggregate or agglomerate, where at least 50% (by number size distribution) of the particles have at least one external dimension in the nanoscale; and
                                                 (b) the industrial chemical is not soluble (within the meaning given by the Guidelines); and
                                                 (c) the introduction of the nanoscale portion of the industrial chemical is not incidental to the introduction of the non‑nanoscale portion of the industrial chemical
