If it were a straight butane cartridge, then no - not at all (it's one of the items you need to acknowledge when checking in.)
Based on your description, the item likely falls under Toiletries and medicinal items. Butane is a common ingredient in a lot of deodorants, shaving creams, etc...
These are best in carry-on, provided they meet the Requirements section below.
