I recently bought some C60OO and it's colour was brown.
I read in the Baati et. al. (2012) study that:
- C60 can aggregate in even the best solvents, turning the solution brown
- the oil used in the study was purple, suggesting little or no C60 aggregation products
- that C60 aggregates may be toxic, unlike the micro filtered solution in the study.
However:
- examination of the cell contents implied brown traces were evidence of C60 accumulation - implying there may be C60 aggregates in the cells.
What colour was the C60oo shipment you received?
Has anyone confirmed the product's composition - like with HPLC?
Do you think the brown C60oo is less safe?
