I hate lawsuits over every little thing too but I'm glad this is being made public.
My MIL has MCS (Multiple Chemical Sensitivity) which is a subjective ailment. She's allergic to all synthetically created fragrances which means not only perfume but also most products such as laundry detergent, fabric softener, soaps, air fresheners, deodorant, make-up, lotions, candles, shampoo, conditioner, hairspray, dishsoap, etc.
We stopped using many of these products years ago due to her issues. Our candles are unscented, cleaning products boil down to vinegar, lemons and baking soda, and we try to buy anything fragrance free. Sadly, even fragrances that are not synthetic are beginning to bother her. This could be pschosematic (sp?) but I can't blame her for being gun-shy when she smells something now. Her skin turns red, ears begin to swell, she gets a headache and can't breathe.
My kids are in their teens and like to use cologne. Since my MIL is now nearly bed-ridden due to emphysema, asthma, and bone-density issues, I've let the kids use cologne. It may seem to you like an odd choice but what I'm saying is that she doesn't come over to our house anymore. I can't tell you how unsuccessful I've been in getting the cologne to wash out of the kids clothes. My record is washing them 3 times in a row and still not getting out the cologne. Either our natural laundry detergent is not effective or that cologne just imbeds itself to a point where it's very noticeable by us because of not having scented products around for so long. We actually buy new Tshirts untainted by cologne if the kids go to visit her.
In some sense I've hi-jacked this thread but it had such a great audience with people who have allergies to cologne that I thought it would be a good venue to raise this awareness.
The worst place of all for a person with this sensitivity (other than the perfume counter at a department store) is the hospital or doctor's office. Every time my MIL go there, she gets more sick because of the number of people who use fragranced items. There are specific instructions that they need to follow--no perfume, perfumed soap, etc. Inevitably, someone uses something fragranced. I can't blame them, everything that's sold seems to be fragranced these days and it's so tempting to smell good.
My heart goes out to all of you with this allergy because this problem is not being taken seriously yet.
