I should have mentioned that the "dry" lubes that I fortify with 10-20% motor oil (after spraying into the squeeze bottle) is what I use on chains. The solvent content is fast-drying, so the bike can be brought into the house soon after lubing, or ridden soon after lubing without any tendency for any lube to fly off, as long as the chain is wiped down thoroughly after application.
The old rule is that "you can't wipe too much lube off of your chain".
Cost per ounce is low.

As far as the "nastiness" quotient, yes these are aerosol products having a propellant. Teflon is fairly inert, but is quite nasty if burned. And silicone is inert. The terrycloth rag that I wipe the chain down with after lubing ends up in a landfill, but only after many, many post-chain lubing wipe-downs. This same soiled cloth is great for wiping down old bikes, gives the most hopeless-looking bikes some color and gloss back.
