So you are telling me that not having a warning label is OK? I disagree. If a pet product should have a warning label, a product for human use should have one also. Yes, you might still get sued, but I bet having a warning label would be better than not listing a warning. If you want to take a chance that is your lookout but I feel better adding a warning label. Even Zest bar soap contains a warning.
Since the original poster asked the following question I assume hers will be considered a cosmetic bar. "I add EO's to my M&P soaps, let's say for a 4oz bar I add approximately 10 drops. Do I need to add the warning about EO's to my labels since it's such a small amount. and, when listing colorants what is the
proper labeling for cosmetic safe?"
Labeling a cosmetic soap bar:
The US Food and Drug Administration (FDA) regulates the labeling requirements for cosmetic products. The label for a bar of soap must contain the following six components:
Ingredients in descending order of predominance
Net weight of soap
The word "soap" displayed on the Principal Display Panel (PDP). This is usually on the front panel of label.
Name and place of business. The street address may be omitted if your business is listed in a current city or telephone directory.
A warning statement whenever necessary or appropriate to prevent a health hazard that may be associated with the product.
Directions for safe use
