For me it's avocado oil. I'm sensitive to a few other things (anything rosemary scented is right out, and I suspect I'm becoming a little bit sensitive to lanolin, unfortunately for my love of MWF), but avocado oil is the allergen I always dread, because it shows up in so many artisan soaps and usually isn't mentioned in the marketing blurb like lanolin often is, so I get my hopes up for a soap only to learn it's a no-go when I check the ingredients. It's to the point that I no longer get excited about hearing about a new artisan soap, because odds are I can't get it because it's probably got avocado in it.
Anyone else have ingredients that you have to scour every new product's ingredients for?
