Determination of Salicylic Acid in Topical Face Cream
at Hobart and William Smith Colleges, Chemistry Dept.
February - May 2018
In a group of four students including myself, UV-vis and fluorescence spectroscopy were used to determine the concentration of salicylic acid in Neutrogena Clear Pore® solution by building calibration curves and a standard addition curve. Three independent methods of determining the salicylic acid concentration were developed. This project was created and designed by the group as a part of an analytical chemistry class.
I contributed to all aspects of the project, as work was divided evenly. I made solutions of known concentration of salicylic acid in water and took both florescence and UV-vis spectra of these solutions to create calibration/standard addition curves, helped with the creation of the subsequent graphs, and participated in the analysis of the data.
