Thanks for all the responses!
I do think I'm pretty sensitive to purfume and get pretty nauseous from it when in an enclosed space.
I'm encouraged though that the smell is a mild vanilla cupcake, because I remember that the version I sniffed was more perfumey and definitely quite strong. I never tried the old version with a different name, but I know she changed the formula of the Clean Cream a little early on. Maybe she changed the scent at that time too.
