Clear: The true color of C-60
For starters, for the better part of two decades now, a purple color has been the standard for determining if a product contains C-60. A purple color!
C-60 turns purple when mixed with Olive oil. Just about everybody who manufactures this stuff makes that claim.
As it turns out, that purple color comes from residual toluene left over from the manufacturing process.
Yeah, you read that right. RESIDUAL TOLUENE! Or, residual amounts of other solvents such as benzene or xylene.
