SEMITI NANO-30 vs BASF Z-COTE HP1
SEMITI NANO-30 is nano TiO2; BASF Z-COTE is nano ZnO. Different actives — many formulators stack them for full UVA-I + UVA-II + UVB.
These are different active ingredients, not direct competitors. BASF Z-COTE HP1 is nano-coated ZnO (zinc oxide); SEMITI NANO-30 is nano-coated TiO2. Each has distinct UV protection profile and formulation considerations.
