Resumen
El plomo es uno de los elementos más peligrosos que afectan la salud humana, ocasionando aumento de la presión arterial y lesiones renales, en las mujeres embarazadas puede causar aborto y en los niños ataca el sistema nervioso. Existen estudios que comprueban la presencia de plomo en labiales genéricos, por lo tanto, el presente trabajo tuvo como objetivo evaluar la concentración de plomo en los labiales que son comercializados por catálogo en la ciudad de Guayaquil. La metodología empleada se basó en realizar encuestas a 150 mujeres con edades comprendidas entre 13 a 55 años para estimar la percepción que tienen al momento de adquirir un producto cosmético. Para el análisis de las muestras se eligieron cuatro marcas de labiales más utilizadas por las mujeres en el sector norte y centro de la ciudad y posteriormente fueron adquiridas por triplicado para obtener resultados más confiables. El contenido de plomo se determinó utilizando la técnica de Espectrofotometría de Absorción Atómica previamente digeridas mediante el proceso de digestión ácida. Todas las marcas analizadas no presentaron concentraciones de plomo con valores <1, 0 mg/kg. cumpliendo con los límites máximos establecidos de plomo como impureza en los colorantes para los cosméticos según la FDA. Finalmente se pudo concluir que los labiales comercializados por catálogo en la ciudad de Guayaquil no representan un riesgo para la salud humana y se plantea que se realicen mayores controles en la comercialización de labiales genéricos en nuestro país.
Lead is one of the most dangerous elements that affect human health, causing increased blood pressure and kidney damage, in pregnant women can cause abortion and in children attacks the nervous system. There are studies that prove the presence of lead in generic labials, therefore, the present work had as objective to evaluate the concentration of lead in the labials that are commercialized by catalog in the city of Guayaquil. The methodology used was based on conducting surveys to 150 women aged between 13 and 55 years to estimate the perception they have when purchasing a cosmetic product. For the analysis of the samples, four brands of lipsticks used by women in the north and center of the city were chosen and later they were acquired in triplicate to obtain more reliable results. The content of lead was determined using the Atomic Absorption Spectrophotometry technique previously digested by the acid digestion process. All the brands analyzed did not present lead concentrations with values <1.0 mg / kg. complying with the established maximum limits of lead as impurity in the dyes for cosmetics according to the FDA. Finally, it was concluded that lipsticks marketed by catalog in the city of Guayaquil do not represent a risk to human health and it is proposed that greater controls be made in the commercialization of generic lipsticks in our country.
