You can view the MSDS for CBG Biotech's "Formula 83" xylene substitute at
www.cbgbiotech.com/msds/MSDS-Formula83071007.pdf It's described as a "naphthenic hydrocarbon blend". I'd note the low flash point (7 C, 45 F), considerably lower than xylene's. Other aliphatic or naphthenic (cycloalkane) mixtures offered as clearing agents have considerably higher flash points. Remember that if you want to recover it by distillation, you must make sure that your still has a distillation routine for it, and you cannot change clearing agents without changing the distillation routine, nor can you mix the solvents and recover them by distillation. If your lab manager shares cost information with you (in my experience most do not) then cost will certainly be a consideration, if it's indeed cheaper than xylene. According to the MSDS, disposal is done like any other aliphatic or naphthenic clearing agent.
