• Resumen

  • This experiment is designed to teach entry-level, nonchemistry-major students some basic organic chemistry through the procedure for making cosmetics. The experiment combines facial toner preparation with distillation techniques to create a stimulating learning environment. During the experiment, students perform a distillation to collect some fragrant components from the plants. By combining this distillate with other ingredients, students learn to prepare a cosmetic product and acquire knowledge in both organic and cosmetic chemistry. Because the facial toner is a colloid, students also learn the properties of colloidal mixtures by investing the Tyndall effect.
