Turnbuckle,
You mentioned that purple color C60evoo might be due to light olive oil(easily oxidizable), and you said C60 mixed with almond oil also has a color of purple, and C60evoo changed a color from purple to brown as it aged. Even so, in Baati's study, C60 mixed with olive oil for two weeks was colored with purple. What do you think of the normal(stable) color of C60 evoo?
There is no normal or stable color of C60EVOO. It depends on the color of the oil and the aging of the mix. Back in 2012 one member here (AgeVivo) obtained oil from the original researchers and posted pictures of it here. As you can see, the original oil appears to have little chlorophyll and thus won't turn whiskey colored, at least not immediately. But once filtered, it is generous to call the color "purple," and once AgeVivo obtained it (possibly years after it was originally mixed), you can see that its color has darkened and turned to mud. Not purple at all. Even the base oil seems to have changed color, becoming lighter while the mix became darker. In a saturated oil, by contrast, the color of dissolved C60 is the classic purple, and is stable, at least over a period of months. A small batch I made early this year never changed. Here is a more recent batch with the classic color also seen in non-reactive solvents such as in toluene.
BTW, AgeVivo then fed this Baati oil over a couple of years to three rats, which all got cancer.
