The FDA has tried to establish official definitions and guidelines for the use of certain terms such as natural and hypoallergenic, but its regulations were overturned in court. That means that cosmetics companies can use these terms on ingredient labels to mean anything they want, with the result that they almost always mean nothing at all. The term all-natural has considerable market value in promoting cosmetic products to consumers, but a close look at an ingredient label reveals that plant extracts make up only a small percentage of the product. Plus, when a plant is added to a cosmetic, preserved, and stabilized with other ingredients, it loses its natural qualities (Source: FDA Consumer Magazine, May–June 1998, revised May 1998 and August 2000).
