The first food and drug act in the US since 1906 went into effect in 1940, it now covered cosmetics. It covered all cosmetics involved in interstate commerce. This law was designed to prevent adulteration, mis-branding and deceptive packaging. No cosmetic could therefore contain poison or harmful substance and could not promise to eradicate wrinkles or anything else it could not actually do! The Industry adjusted to the changes and survived providing the public with better quality and accurately labelled cosmetics.
