I want to start making and selling bath bombs but I have a few questions on them. 1. Labeling requirements for NY. I have only found UK, and EU questions about them, and I've been trying to do research on it. 2. Are they safe? Is citric acid, baking soda, essential oil, etc safe for prolonged contact. I know there are potential allergic reactions to them so I am curious to what I should "label" to cut down on liability. Example: "keep out of reach of children" "do not eat". Etc. 3. Are they considered cosmetics and have to be tested by the FDA?
