Dr. Christina Peterson, a headache specialist near Portland, OR and founder of the Migraine Survival website, sent the following information about potassium dichromate, the dangerous active ingredient in HeadOn. She wrote:
“I would state it even more strongly. Here is the MSDS [Material Safety Data Sheet] for potassium dichromate. Here is just the toxicology section from the above:
‘Hexavalent chromium compounds are generally more toxic than trivalent chromium compounds. May be fatal if absorbed through the skin, if swallowed or inhaled. Contains chromium (VI), a known cancer hazard. Allergen. Corrosive. Skin eye and respiratory irritant. May act as a sensitizer. Typical PEL 0.5 mg /m3.’
[It is] an oxidizing agent, used in pyrotechnics, explosives and safety matches.
I can only imagine it is being allowed to be marketed because a) it is not generally absorbed through the skin and b) the concentration is fairly low. I certainly would not risk skin cancer when there is zero evidence of either efficacy testing or safety testing.”
For more information on potassium dichromate, Dr. Peterson provided links to the American Chemical Society’s Chemical Laboratory Information Profile and a detailed MSDS from chemical company Mallinckrodt Baker.
It’s not getting anywhere near my skin!
Thanks for the information, Dr. Peterson.
