I think the acetone is there as a "carrier" for the lubricant, to make it a bit easier to apply. It would then evaporate after being exposed to air.
It's concentration is likely very low, or it would damage the rubber.
Can't imagine DuPont saying to use it on rubber, knowing acetone in concentration would damage the rubber. It isn't all or nothing...depends on the concentration and for how long.
I'd use it. JMHO.
