Item Producto cosmético a base de arcilla montmorillonita intercalada con aminoácidos para regeneración de la piel(Universidad Santiago de Cali, 2022) Romero Manzano, Sara Carolina; Leiton López, Silvana Anyolina; Ríos Acevedo, John Jairo (Director)This project evaluated the impact of incorporating amino acid-modified montmorillonite clay into an O/W cosmetic body cream on its sensory, physical-physicochemical, and microbiological stability properties. In this way, it was started by intercalating glycine, glutamine, and arginine within the previously purified clay structure by the cation exchange method and characterized by infrared spectrophotometry and thermogravimetric analysis. The intercalated clay was added to a standard cosmetic formulation and finally the physical-physicochemical, organoleptic, and microbiological stability parameters were compared in a cosmetic product with and without clay. Regarding the physical stability studies, the phenomenon of agglomeration and cremation was determined. Greater extensibility and less density were presented in the cream without clay. The microbiological studies complied with the parameters evaluated and in the organoleptic properties the cream without clay presented better acceptability in terms of its color, smell, adherence to the skin, soft sensation, and creamy texture.
