Hello,

If one were to acquire a substantial amount of 99,95% pure C60 powder, would it keep for years?

I know very little of the properties of c60, but I have a hard time imagining how it could turn bad. Or am I wrong on this?

How would you store it to ensure maximum shelf life? Freeze it?

Any info of c60 shelf life out there? (I'm talking about the pure fullerene powder; not C60 + olive oil)

Thanks.

If it was kept in a sealed container, dry and in the dark, preferably cool as well, I would expect it to keep for years.

Really, 60 powders should be kept in a sealed container, dry and in the dark. In that case, and in accordance with our experience, they can be stored tens years without loss of their quality.
Nevertheless, working with C60 powders it is necessary to avoid their prolonged contact with air, especially with humid air, because during like contact the microcrystals of C60 powder are capable to adsorb and keep strongly on their surfaces the oxygen, nitrogen and other molecules which are present or can be present in air, including especially molecules of water and ammonia.
Adsorption of similar molecules on C60 reduces essentially as molecular (non-cluster) solubility, and C60 solubility as a whole in hydrophobic organic solvents and in ÎÎ also.

Thank you.

Your post was very helpful.

I wonder how long it would keep in EVOO. At what I am guessing will be my monthly dosage for myself and my dog, a gram will last a little about 2 and half years.

Since I bought my EVOO in 500ml bottles, I will probably just keep one out all the time in a cool/dark place and freeze the other two until I am ready for them.
