The specific mix of chemicals in F550 is a trade secret. The constituent chemicals themselves appear on F550's MSDS. I think the article is misleading on this point, saying that research is just starting on F550 (yes, academic research, at a program just started to evaluate all flame retardants) and that the EPA hasn't studied it (because the EPA isn't the agency most responsible for doing that).

PBDE's haven't been used for years.
