Not sure if I'm supposed to reply here as all of the threads are being moved across but couldn't believe it when I saw your thread so going to post and hope it's in the right place
I've just found out that I have issues with sunflower oil (I think it would be termed an intolerance rather than a full blown allergy) but it's literally stopped me living my life as I couldn't figure out what it was that was causing me to feel so ill all the time. Anyway...it seems that the intolerance has got worse over time. With regard to fragrances, a few years ago it was only one or two air fresheners or perfumes that bothered me, now it's many many more. I emailed The Perfume Shop to ask whether they could advise re ingredients but they simply got back to me and said that none of the perfumes they stock contain sunflower oil etc. I think this is incorrect as I've since researched it more thoroughly and some perfumes to do contain halianthus annuus and other ingredients which I think are alternative terms for sunflower derivates but I'm not completely sure.
I have issues with Neutradol air fresheners, Ralgex spray, Obsession perfume, Lee Stafford hair products and quite a few others. It seems to be the smell of the fragrance that causes me problems as I don't have to be using the product itself. Do you mind me asking what sort of reaction you have? For me it's like a migraine type feeling with a lot of pain in my face (similar to blocked sinuses), I kind of feel like my head is full of something and no painkillers seem to work. I just have to lie down and hope that it goes.
In my opinion, being affected by fragrance is the worst aspect of it because I can control what I eat, what make-up I wear etc but if I go out and someone happens to be wearing perfume that provokes a reaction then I feel unwell immediately.
Would be really interested to hear from anyone else who has a similar issue and if you've had any luck clarifying ingredients with manufacturers.
