dc.description.abstractThree different kinds of cosmetics were analyzed: Anti-pickle (product from German), Innisfree Green Tea facial foam cleanser (product from Korea), and The ordinary AHA 30% + BHA 2% peeling solution (product from UK). These products were measured by the matrix assisted laser desorption ionization (MALDI-TOF) technique. The analysis was performed using a Bruker Daltonics software 3.4. Two different matrices (DHB and ACCA) were used to examine the best results. As a result, DHB were used as a matrix because the sample appear higher intensity, resolution, and has more peak than ACCA. After calibrated, each product has different substances appear in the spectrum which indicated by their m/z. Isotopepattern were used to identify compound and determine the accurate theoretical molar mass.
