Cosmetic ingredients may not be listed on the prohibited list of ingredients. In addition, cosmetic ingredients may not be harmful when consumers use the product according to the labeled instructions or customary or expected way. There is one exception for coal-tar hair dye. FDA can not take action against a cosmetic company with coal-tar hair dye so long as the appropriate warning appears on the labeling "Caution - This product contains ingredients which may cause skin irritation on certain individuals and a preliminary test according to accompanying directions should first be made. This product must not be used for dyeing the eyelashes or eyebrows; to do may cause blindness."
The following cosmetic ingredients have specific regulations either restricting its use or prohibiting its use:
Prohibited cattle materials due to "Mad Cow Disease"
Sunscreens in cosmetics. This results in the cosmetic being classified as a drug. It's not that sunscreen can not be added to a cosmetic product, but the use is restricted and there are specific drug regulations that the cosmetic must now comply with.

Specific color additives are permitted in cosmetic ingredients. In addition, each color additive is limited to what part of the body and/or face it can be used. Furthermore, color additives in any product are regulated by FDA and require that some color additive batches be tested and certified by FDA prior to being used in a product being distributed in the US.
