No, they don’t have to reveal everything. They have to account for everything down to 0.1%, or 1,000 parts per million, but they don’t have to identify everything if they’re using the “Manufacturer Inventory” or HPD pathways. They have the option of listing some ingredients as “proprietary,” but even for those they still have to identify what the function of that substance is in the product and what health hazards it represents, if any.
Question:
Does a manufacturer have to reveal everything that’s in a product to comply with the transparency option?
