Hi Eva!
I have some micronized zinc (i have both the coated an the uncoated so don’t worry about this ) I want to mix in my sunscreen witch has the folowwing UV-filters
Diethylhexyl Butamido Triazone ( aka Iscotrizinol, Uvasorb HEB )
Diethylamino hydroxybenzoyl hexyl benzoate (Uvinul A Plus)
Ethylhexyl triazone (Uvinul T 150)
Bemotrizinol (bis-ethylhexyloxyphenol methoxyphenyl triazine, Tinosorb S by BASF and as Escalol S
Does anybody here know if the zinc powder would un-stabilize the filters or should It be OK to mix in?
Those filters are fine with zinc oxide, but your sunscreen is probably not. You can't just add zinc oxide to an existing sunscreen. It will likely ruin it.
