I am allergic to methylchloroisothiazolinone which which is found in some ET products.
I had been using products for years with it in and suddenly reacted severely from using the soothing moisturiser (j think it was that one)
This lead to patch testing, which was handy!
I now have massive reactions if i come into contact with it.
Now it wasn't the product that was bad, it was a straw that broke the camels back kind of situation.
I mention this because it is now a known allergen and more people are reacting all the time.
It's a shame because I liked the range and would have took it on.
I spoke to a nice person from ET at PB who was very helpful and they said they are taking steps to remove it but it takes time.
