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.

Time-Dependent Changes in a Shampoo Bubble Arun Chattopadhyay
This article demonstrates the fascinating phenomenon of time evolution of a shampoo bubble. The changes in thickness of the bubble films with time are followed by UV-vis spectroscopy. The change in chemical composition as a bubble film evolves is monitored by FTIR spectroscopy.
