There are several federal agencies that play a part in the regulations that cover soap and cosmetic labeling.  Checking their websites will provide details.  Also checking the actual regulations in the Code of Federal Regulations is good.

Helping the handcrafted soap and cosmetic industry has been my passion for nearly 20 years now. With this blog and answering questions sent to me, I try to provide accurate information freely and to assist those making soap and cosmetics to follow the rules and regulations. While others may charge for answering questions or create paywalls to access the data, I will always try to provide the important and necessary information freely to all.

If you feel this information has been valuable to you, helped you, and would help others -- and if you can afford it -- a small payment to help offset the time, effort and cost of providing this information would be greatly appreciated!
