Re: labeling requirements in the US as Carolyn mentioned. Just in case you are interested. Soaps can be classified as only soap, or as a cosmetic, or as a drug, or as a cosmetic and a drug. When the latter two, there are specific labeling requirements. The best source I think for clarity of labeling requirements is Marie Gale's book, Soap and Cosmetic Labeling. But since she bases her book on the regulations of the Federal Government, you can peruse the Federal Regs as well. Marie Gale's website on Soap & Cosmetic labeling: https://www.mariegale.com/soap-and-cosmetic-labeling-book/ Marie Gale's labeling Quick Guide FAQ's: https://www.mariegale.com/quick-labeling-faq/ Here are links to the FDA site (USA) regarding labeling requirements. Summary of Labeling Requirements: https://www.fda.gov/Cosmetics/Labeling/Regulations/ucm126438.htm Cosmetic labeling guide (pertains to some soaps, depending on claim or customer perception): https://www.fda.gov/Cosmetics/Labeling/Regulations/ucm126444.htm Small Business & Homemade Cosmetics Fact Sheet : https://www.fda.gov/Cosmetics/ResourcesForYou/Industry/ucm388736.htm Some say that if you sell your soap and say it is only soap, that it can be sold without a label. However, that's not entirely true in all cases. If public perception believes that pine tar soap is medicinal, then no matter what you say, you need to label it as if it were a drug because you cannot know that your customers won't be buying it for medicinal use. Meeting the labeling requirement as such protects you as a business owner. Additionally, fragrances and especially some Essential Oils should be listed because there are safety precautions that are important for those who would be affected. It is important to buy from a reputable vendor who lists safe usage rates in soap and to follow those, as well as to list the possibly problematic ones on your labels. Examples of some essential oils cautions by vendors: See these sites for cautions on EOs they sell that should not be used by pregnant women: https://www.rockymountainsoap.com/pages/pregnancy-and-essential-oils http://www.wholesalesuppliesplus.co...ke-articles/Essential-Oils-And-Pregnancy.aspx This is not an entirely exhaustive listing. Just a few references that may help when it comes to labeling.
