Pre-Calculated Safety Assessment
Conditional — safe only within SCCS limits: aluminium assessed as AGGREGATE systemic exposure, not per-compound (SCCS/1644/22 Table 18): all cosmetic routes summed = 0.80 ug Al/kg/day vs POD 180 ug/kg/day = MoS 225; safe in all cosmetic categories at maximum use-levels (Tables 4/6); aerosol sprays require under 20% of particles below 10 um
