Who is in charge of regulating claims like Natural and Organic for personal care?

Technically it is the Food and Drug Administration but they have not set official definitions for either Natural or Organic.

If you see an organic seal on a product, that is from the US Department of Agriculture and it is a food-based certification. It is certified and means the content of the product has been certified to be at least 95% organic. Our Organic Coconut Oil is 100% organic.
