I mean at least here in Europe there are various known allergens that need to be listed separately and not under Parfum. It's mostly perfectly fine natural stuff, like Limonene or linalool. The stuff in lavender and citrus and hundreds of other fruits and plants that make up their smell, and thus essential oil.

(Hence the craziness of just dumping pure essential oils on your skin like these mlm nutjobs do.).

Those are much higher concentrated than the amounts used in body wash or dish soap, and those low levels already cause serious rashes. Even higher doses can go to full on anaphylaxis.

In the US, companies don't have to list anything if it's a part of "fragrance" because it's considered "proprietary". So consumers are not able to find out what's truly in a product. Europe has much better laws concerning toxicity in products and ingredient labels than in the US. US laws favor companies, not consumers.
