This Talcum Powder cancer scare lifted its head here some twenty five years ago, and it all emanated from some flawed research done but I cant remember where. The final result was the link was not probable and tenuous at best. I am sure you know that court cases that are not cut and dried can cost litigants an arm and a leg here especially if it went to the High court. So the news media hype on Talcum powder fizzled out, so Talc is freely available here.
May be it is far easier to go to court on such research on your side of the pond than here?
