Keep, or redirect to formaldehyde?
[edit]I'm not sure whether this article would be better as a mere redirect to formaldehyde, though there appears to be current research, at least, specifically into methanediol (a google search for "mehtanediol", at least, gives me that impression).
Opinions?

Methylene Glycol: Brazilian Blowout (TM) lists on MSDS (Hair Straightening technique utilizing formaldehyde heated as 'formica')
[edit]Please, will someone with an I.Q. please check the MSDS of "Brazilian Blowout." It is a very expensive and trendy technique for straightening hair. They claim: "no formaldehyde" yet, here it is on their Material Safety Data Sheet under another name. Cosmetologists are not trained to identify Methylene Glycol as such. Therefore, they fail to protect themselves and their clients, especially when 'finishing' the treatment with an extremely hot flat iron at 450 F. This is the exact temperature required to turn it to a gaseous state and bond 'formica' to the hair shaft.
Cosmetologists are trained by "Brazilian Blowout' that they are giving a "keratin" treatment.
Please list this ingredient accordingly that others may learn and protect themselves.
