The FDA only requires that companies label their products with ‘fragrance’ or ‘fragrances’ when in reference to the ingredients that provide any given product with a scent.
The FDA (or through any sort of federalized guidelines) should require that all products sold into US Markets be made with natural fragrances, and all products to have an extensive/transparent list of ingredients.
Any sort of sythentic product should have to adhere to the same testing standards as pharmaceutical drugs.
