Not sure if you were intended to exclude some botanical oil based skeeter repellents.
this from the first link in the Google hit list:
In response to a question about bears being attracted to citronella, in the February 2003 issue of Backpacker magazine the “bear expert” wrote about “several years” of research in “Alaska to test how bears respond to different sights, sounds and smells. Citronella powerfully attracts some male and female bears. For some individuals of both sexes, it elicits rolling and rubbing that can last for 5 to 10 minutes… We know of no attacks on people triggered by wearing citronella, but because of its bear attraction power we don’t recommend wearing it in bear country.”
cautions against perfumes and shampoos, i’m guessing are also aimed at the botanical aspect of them and not merely the chemical solvent aspect.

[Note: above list is “lifted” from MountainNature.com]
don’t know if the above list is comprehensive/exhaustive. there’s those catch all items “Berries and Fruits”, “Herbs and others” and “Grass and Grass-like Plants”. since they’re omnivores, anything that might smell like bear-food is a potential attractant.
