What historical legislation distinguishes between drugs and cosmetics?

The Cosmetic Act of 1938 is pivotal in defining the distinction between drugs and cosmetics within the United States. This legislation established the legal framework for regulating cosmetic products, outlining specifications regarding labeling, safety, and efficacy. The act provided clear definitions which classify cosmetics as products intended for beautifying or altering the appearance, while drugs are defined as substances intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease. By creating this distinction, the Cosmetic Act helps ensure consumer safety by holding cosmetic manufacturers accountable for the safety of their products, while also allowing for appropriate regulation of drugs, which have different intended uses and safety requirements.

The other legislative acts mentioned do not focus directly on the classification of drugs and cosmetics. For example, the Food Drug and Cosmetic Act of 1954 is an extension and update of earlier laws, but it does not specifically create the differentiation established in the 1938 act. The Pure Food Act of 1906 primarily addressed food safety and standards without delving into cosmetics. Meanwhile, the National Health Act of 1944 was concerned with health measures and funding rather than the specific regulation of drugs and cosmetics. Thus, the Cosmetic Act of 1938 is the key legislation for understanding the distinction.
