In general you should indeed give each Deo without aluminum salts a good review - but that would ignore effect and fragrance. As already indicated, this 8x4 Deo works without aluminum salts. Since aluminum in the living world exists nowhere and the cases are increasing, in which the metal is associated with disease (the proof of the causal connection is still made mW) should - if possible - but without it. The 8x4 has a distinctive albeit little intrusive scent, the one does not necessarily should be combined with other scents - that comes to light in the way. The deodorant protection is slightly higher than one day. Longer acting deodorants should rather avoid anyway, because this fight already with quite rabid chemical bludgeons the body sweat.
