Patient discussion about platinum.

Q. I was told that platinum is used in fragrances for the fullness of the spray. Please tell me more! Three years ago I was diagnosed with off the lab chart levels of platinum in my body. I have no hobby or avenue for exposure other than my work. I have sold fragrances for over ten years. Even the Regional EPA Air Quality person doesnt know where I am getting this. I was told by a health director who made some calls. He told me that platinum is used in fragrances for the "fullness of the spray". Would you please tell me more about this? Thank you!

A. i never heard of it. but i know that there are alot of materials in fragrance spreading instruments that are not healthy. some do use metal salts, and in a large quantities it can be harmful. about Platinum- you can look on the lists of materials or send it to a lab to check it out.
