IFRA is the International FRagrance Association - a trade association for the fragrance industry first formed in 1973 (though pre-cursor organisations go back to the sixties). It is, in short, the fragrance industry itself. It isnít government in any country.
The Standards that IFRA maintain, and that so often look like the bane of every perfume-lovers life, are compulsory for IFRA members and guidelines for everyone else. They are an attempt by the industry to pre-empt government regulation of the industry - it has been largely successful outside the EU and even within the EU has certainly prevented a lot of the legislative intervention that might otherwise have occurred.
I canít say Iím a fan of the Standards, nor am I a member of IFRA but I do at least prefer having one set of rules to follow that apply pretty much everywhere, rather than umpteen variations throughout the world - though of course that isnít completely true either, it does help.
