To the uninitiated, formulation of shampoos seems easy! It’s a one-phase, water-based surfactant blend that foams! Simple, isn’t it? While that may indeed be the case when compared to inherently unstable systems, such as emulsions, many complications may arise that make it a more complex task than may first meet the eye.

Personal care products for men and women have traditionally been formulated differently. Products for men are usually characterized by the presence of alcohol, which has rarely been used in cosmetics for women. The appeal to the two groups is also distinct, with men seeking well-being and health and women pursuing health and beauty. Men treat their skin in response to a need, such as shaving, cleansing, and treating cuts and nicks. They are less prone to viewing skin care as an aging-prevention or appearance-enhancing practice. Analysts report, however, that this attitude is changing.

Both the cosmetic industry and the Food and Drug Administration (FDA) have had a long and interesting history. FDA’s history began in 1906 with the enactment of the Pure Food and Drug Act. This was the first attempt to regulate the safety of products (or additives). For almost 100 years Congress has set the standards and published them in the United States Code (USC). FDA and other federal agencies promulgate regulations through notice and comment rulemaking. Proposed regulations are published in the Federal Register (FR) and the public is given an opportunity to comment. The agencies then publish in the Federal Register final regulations together with a preamble discussing each comment. Industry and regulatory scientists eagerly follow these changes and access them on the Web. Final regulations are compiled in the Code of Federal Regulations (CFR).
