As I am sure you are probably aware, in order for regulations to go into effect in any country or union of countries, the lawmakers have to agree. Before that, they review information from expert sources. The expert sources have to have some sort of consensus. In some cases, hearing or feedback is sought from the public or the affected parties, such as happened in the US when we were asked to give feedback on what 'natural' means. In any case, it is not an easy or even forthright process. It takes time, a lot of effort and real concern for the welfare of the consumer; and it can also be a balancing act. There's a whole lot more to it than that, but I'm long-winded enough as it is.
Regarding what is 'natural' or even 'organic' in the US, these are meaningless words in the arena of cosmetics and soaps. The FDA does NOT have definitions for them (
reference) so labeling something natural or organic may be misleading, in that even the FDA recognizes 'natural' means something different to different people. And 'organic' is regulated by the USDA. So the label might state 'made with organic' whatever-ingredient, which is probably fine, but if the manufacturer claims '100% organic' it's the USDA who regulates that part of the labeling. The FDA still regulates the label as it pertains to the product's intended use and what it qualifies as by FDA definitions. Some soaps qualify as cosmetics and some qualify as drugs, which have stricter labeling requirements.
Regarding the soap (if it is a soap) in your post #104 in this thread: If that was sold in the US, it would qualify as a cosmetic because of the claims. Therefore, it would have to adhere to cosmetic regulations in the US if it were sold in the US. As long as the seller follows the rules for labeling the soap as a cosmetic, then they should be okay.
If they claim a cure or a psychological benefit or that the soap is for treating a medical condition, then it is a drug, and the drug regulations apply. (
