Item Espectrometría de masas aplicada en la estabilidad de un producto cosmético para el cabello(Universidad Santiago de Cali, 2022) Chavez Espinosa, Yadid Milena; Velásquez García, Natalia (Directora); López Parra, Lizbeth Lorena (Directora)Five different formulations of hair masks were made, varying the amount of Polysorbate 80 and Glyceryl Monostearate, in order to establish which surfactant presented the best stability in the emulsion. For the different hair masks, chemical stability tests were carried out under natural and accelerated conditions for 4 months, measurement of pH, creaming index, viscosity tests, centrifugation tests and analysis of volatile components at week 0 and week 16, by means of Gas chromatography coupled to CG-MS Mass Spectroscopy. It was observed that the ideal hair mask under natural and accelerated conditions to establish a formulation is the hair mask that has 5% Glyceryl Monostearate in its composition, due to the physicochemical stability it presented over time. Finally, it was established that the volatile components did not show significant degradation in the different hair masks.
