plat·i·num (Pt),

(plat'i-nŭm),
A metallic element, atomic no. 78, atomic wt. 195.08, used for making small parts for chemical apparatus because of its resistance to acids; in powdered form (platinum black), it is an important catalyst in hydrogenation. Some of its salts have been used to treat syphilis. A derivative, cisplatin, is used as an antineoplastic agent.

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. Thank you Joseph83! What list of materials shall I look at? I know that the FDA doesn't regulate these products; also, I wonder if there is a masking name for platinum. I have so much of this in me, it just has to come from somewhere! I'm amazed that the EPA SUPPOSEDLY doesn't know where its coming from either.
