The law does not require cosmetic products and ingredients, except for color additives, to be approved by FDA before they go on the market. However, cosmetics must not be adulterated or misbranded. This means that they must be safe for consumers when used according to the labeling, or as people customarily use them, and they must be properly labeled. To learn more, see Key Legal Concepts: Interstate Commerce, Adulterated, and Misbranded.
With the exception of color additives and ingredients that are prohibited or restricted by FDA regulations, you may use any ingredient in your cosmetic, as long as it does not cause the product to be adulterated in any way. You are legally responsible for making sure your cosmetics are safe and properly labeled, in compliance with all the laws and regulations that apply to them.
Remember, however, that not all “personal care products” are regulated as cosmetics under U.S. law. For example, some are regulated as drugs. If your product is a drug under U.S. law, it must meet the requirements for drugs, such as premarket approval.
