There is nothing smart about SP using titanium dioxide as a filler. A quick reading of Wikipedia confirms it has safety issues having to do with yellow nail syndrome. Anyhow, discussion of it is off-topic for this thread.I guess that's because SmartPowders includes titanium dioxide and other fillers which I don't think is the case of VosunChem.
I think this is legit but I don't have proper material to make further testing.
Powder is almost white, SP's is whiter but that's because of titanium dioxide.
