A Comparison of the Components in Bar Soap and Body Wash by Solid Phase Micro-Extraction

Soaps are made of fats and oils reacted with lye while body washes are primarily made of water and surfactants. Most bar soaps have a pH of around 9 which can be drying while body washes ideally have a pH of about 5.5 which is similar to a person’s skin pH. While soaps and body washes come in an abundance of scents, some people prefer unscented. This application will compare the volatile and semi-volatile components in unscented soap and body wash.
