Here is a home made C60-evoo preparation that has worked well for me after reading the guidance of other frequent Forum contributors like Turnbuckle, Niner and others.
Recipe:
1.0 gram SES 99.9% purified C60
1200 mL Trader Joe's Kalamata EVOO, $8.99/1L
Transferred 1.0 gram SES C60 powder into Vktech Mortar and Pestle,Stainless Steel (Amazon). Ground dry C60 powder vigorously for about 2 minutes until dry grinding did not appear to comminute the powder further. To ground powder in mortar added with a plastic pipette 2 mL evoo. Wet ground about 30 seconds to an inky deep brown slurry. Using same pipette transferred slurry into 1500 mL clear narrow mouthed glass jar. Then from the Trader Joe's Kalamata EVOO bottle dripped into the mortar about 3 - 5 mLs EVOO and worked with pestle to rinse off all internal surfaces of mortar & pestle. With each small aliquot of EVOO used to rinse mortar & pestle transferred each portion into the 1500 mL clear glass jar. Repeated rinses of mortar & pestle about ten times with 3 - 5 mL EVOO until all stainless steel surfaces looked shiny and clean. At this point was confident that all the C60 powder was transferred into 1500 mL clear glass jar.
To the 1500 mL clear glass jar poured the remaining EVOO from the 1L bottle from Trader Joe's. Opened a second 1 L bottle of Trader Joe's Kalamata EVOO. Measured out 200 mL into a Pyrex measuring cup, then poured this into the 1500 mL clear glass jar. The total EVOO liquid in the clear glass jar should total about 1200 mL. Capped the jar with a polyseal cap and shook vigorously.
Shook clear glass jar with C60/EVOO mixture vigorously for 30 seconds 2 - 3 times per day. Within 72 hours the c60 appeared to have completely solublized into the EVOO to provide a light rose colored water clear liquid. After sitting for a few hours just a whisper of black residue was visible on the bottom of the jar.
I decant off the liquid into 9 brown glass 125 mL wide mouth polyseal cap jars, leaving a small amount of EVOO with the whisper of black residue in the clear mix jar to discard. You can filter the C60-EVOO liquid easily with 0.45 micron glass fiber syringe filters, but it seems as though the C60 has fully dissolved as the EVOO adduct. I freeze these jars then thaw one by one for use.
This method is way faster and the resulting C60-EVOO solution has a color much closer to that from the C60oliveoil.com versus the coca-cola color of products from VW or BuckyLabs. The first time I prepared C60-EVOO I crudely crushed the 99.9% SES C60 in a small bowl with the back of a spoon. It took literally 3 weeks for the C60 to solublize and the resulting C60-EVOO liquid was coca-cola color, not faint reddish. So it appears that the longer the C60 is at room temperature in air it progresses toward the coca-cola color as I've used the same Trader Joe's EVOO and the color of this as purchased olive oil product doesn't seem to vary greatly to my eye.
I've wondered if C60oliveoil.com does something similar, crushing to a fine powder &/or inerts their mixing process with an atmosphere of nitrogen, argon or carbon dioxide to preclude oxidation.
Anyway, thought I would share.
