I don't mean to necropost (if this counts as a necropost I am SUPER SORRY). I recently communicated with Bulkoils.com. In the beginning they wouldn't tell me their vanillin content because they said it was a trade secret. When I explained the reason why I asked they told me whether or not the scents I was asking after were 0% vanilla. It can be aggravating to ask about an entire list, and this doesn't even begin to address acceleration/ricing/seizing... but they will communicate if you e-mail. I don't think they test their FOs in soap, they seem to be much more of a candlemaking FO site.
