Making Usable, Quality Opaque or Transparent Soap  Suzanne T. Mabrouk
First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

Our Everyday Cup of Coffee: The Chemistry behind Its Magic  Marino Petracco
Coffee beverages are so popular all over the world that there is hardly any need to describe them. But underlying this seemingly commonplace beverage there is a whole realm worth serious scientific study. The complexity of the raw seed matrix, made even more intricate when roasted, requires a deep understanding of its chemical nature. While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product.

Cocoa butter is a significant ingredient in chocolate, and an investigation of it introduces triglycerides, fatty acids, polymorphic behavior, and molecular packing of the fats in chocolate and how they affect the tempering process. There is a brief discussion of chocolate's non-Newtonian behavior and the resulting challenges presented in the manufacturing process.

Consumer Views on Chemical Additives: Are They Natural or Synthetic? A Non-Laboratory-Based Project  A. S. Cotterill, D. N. John, and Y. S. Teh
Results of a study demonstrate that consumers are not well informed about identifying natural products but do recognize names to which they have been exposed. Consumers also appreciate that natural compounds can come from a variety of sources and can be synthesized, and that a natural substance is not necessarily good for you or better than a synthetic substance. However, despite this knowledge, consumers do prefer products that contain natural or natural-sounding additives.

The Fizz Keeper, a Case Study in Chemical Education, Equilibrium, and Kinetics  Reed Howald
The chemistry of the loss of carbonation from carbonated beverages on storage is considered. Increasing the pressure of CO2(g) will restore carbonation, but an increase in pressure adding air should not affect the equilibria. It can and does, however, affect the kinetics-the rate at which a new equilibrium is established. Thus the Fizz Keeper is effective for storage of resealed pop containers for hours, but not for periods of weeks or months.
