Here's one example:

It is my post, but I learned about IFRA here at SMF, as well as the soapmaking seminars I have attended in the first couple of years of soapmaking. And I am not the only member here who has made that recommendation or included a link to the actual IFRA website for finding safe usage amounts.
Here's the link to the International Fragrance Association (IFRA) standards website where I go when I want to look up safe usage information:
http://www.ifraorg.org/en-us/standards#.XLtbR6ROm00
I do understand that the EU does have stricter rules in regards to certification of cosmetic products which in the EU includes soap, but am not as familiar with them since I have no experience in that arena. But I do notice that there are sections on the IFRA site that specify EU and UK information, but I haven't read the linked articles. The US federal regulations for soap are somewhat different, as not all soap is considered cosmetic, so that is one major difference. Although some smaller municipalities (states and local governments) who do sometimes have stricter regulations within the US.
I am not saying I don't believe you about the site you mentioned. I just wanted to point out that IFRA is used by some fragrance sellers in the US (here is one example of a US seller of FO's that uses IFRA in its sales of FO's:
https://rusticescentuals.com/Jasmine-White.html) and that some (maybe many) soapmakers in the US do follow IFRA guidelines because it is wise to do so.
And another example of a US company that sells IFRA compliant fragrances (and includes allergen information as well):

No you did not offend me at all. I just was attempting to clear up what I felt was a misunderstanding.
I tried looking up the website you mentioned, but my Google search for "whicknwhacks" was not forthcoming.
Do you have a link? I would be pleased to read through it and learn a bit more about what you are saying in regards to the American brands of FO's they are selling. But to be clear, not all FO's or EO's are safe in soap or any other product to touch the skin, so that would not surprise me. Some fragrances are sold to be used only in wax melts, etc. So maybe that's the type of fragrances they buy from the US. I don't really know, of course, but that seems most likely to me. I could be wrong of course, because, as we all know, not every company that makes or sells products is necessarily scrupulous.
Okay, I found the site (your previous post left out a letter, which is why I couldn't find it at first), if this is it:
https://www.whicksnwhacks.com/about-us-1-w.asp
I will read a bit on the site to get a picture of what you are seeing.
Okay, is this what you are referring to:
"Although these oils are passed for use in soap and body products in the USA, due to additional EU requirements they are not considered to be suitable for use in bath and body products in the EU without additional allergen testing to comply with EU regulations."
That makes sense to me. It's the allergen testing that the EU requires that the source in the US has not provided. Allegen testing of cosmetic products in the US is probably not as strict as the EU, at least not yet, and who knows if it will ever be the same.
Of course they don't say what vendors in the US they got those products from, so that's not to say all US vendors don't include the required information. After all many US soap manufacturers also sell in the EU and they are required to follow the rules for sales in the EU, same as the EU based companies. So those companies (Proctor & Gamble, is one example - they make Irish Spring, which is available in the UK, as I found it there.)
