I think, perhaps, there is more work reading  the legalities of packaging than producing a product. According to the FDA Packaging and Labelling cosmetics, ... if an ingredient is "trade secret" they (the manufacturer) under certain conditions, are under no obligation to include it on the ingredients list.

Packaging really is an artform in itself. After all, that is what we are buying. The contents within are incidential and don't need mentioning. Apparently

And there is a little confusion with Health Canada, if an item is on the hotlist, manufacturers are permitted to use if within the HC amounts. If it is not on the cosmetic hotlist.... can they still use it even if there are MSD's stating that it causes skin irratation and not tell us? I need to reread, and ask another question.

Are not the ingredients listed so the consumer can make an informed decision? How can we?

It is kinda misleading,... seeing a pattern yet?
