Honestly, the lighter is a cool idea and all, but in an abduction situation I would seriously discourage trying it. She'll be damn lucky if she has time to retrieve the can, figure out which way its aimed, rotate accordingly and squeeze off a stream without having to use up another hand (her only free one), fumble for bic lighter (small and hard to pick out of a crowded purse), orient it correctly, ignite it and line the two up in the direction of the attacker and squeeze of a fireball.

Keep it simple.

One shot of BrakeCleen in the face - aim for the upper lip and not the eyes. The point is to induce unconciousness. If you only hit his eyes, he's still awake and can lunge forward and still grab you but if any of that stuff gets in his lungs, he'll drop like a wet dishrag and be out cold for a good while. Besides, if you hit his upper lip some will probably get in his eyes anyway but you could easily hit his eyes and completely miss his nose.

Its not lethal - he'll wake up after a while with a migraine.

Other than playing around in the garage, I'd pass on the deodorant idea - not all of them work as flamethrowers and I don't think any of them would incapacitate an abductor - none of them contain solvents in sufficient concentrations.
