What's T-9 
A Boesheild product. It is sold and used for stuff other than bike chains. The aircraft industry use it as do gunsmiths and enthusiasts to name a few other uses. It comes in aerosol cans, squeeze bottles, and in larger (gallon etc) cans. Bike shops tend to have the small squeeze bottles or sometimes the aerosol cans. I think it is paraffin based.
It says it's paraffin based on the bottle.
A mechanic once advised me "Use the cheapest chain you can find and change them every 800 miles" I may try that in future: not the most convenient for a long tour but I find the chain cleaning quasi ritual a PIA and I'm not sure it makes them last any longer.
