Abstract

RODRIGUEZ-ROSALIO, Vania Montserrat et al. Determination of lead in different brands of lipsticks marketed in Mexico. Ing. invest. y tecnol. [online]. 2023, vol.24, n.4, 2039.  Epub Nov 28, 2023. ISSN 2594-0732.  https://doi.org/10.22201/fi.25940732e.2023.24.4.028.

Cosmetics have become a common use product among people around the world being the reason why it is important to know their components specifically, the presence of heavy metals. The content of lead in branded lipsticks was analyzed due to the cause of a large number of diseases and disorders in users. The study was aimed at assessing the levels of lead concentration in 5 lipsticks of different brands sold in Mexico but produced in different countries. Characterization was carried out through a flame atomic absorption spectrophotometry in which the analyses showed the presence of lead in all the samples with a concentration ranging between 1.1775 ppm to 1.8242 ppm, with an average concentration of 1.457 ppm, these concentrations are within the average parameter established by the FDA (Food and Drug Administration). However, lead content in daily products, even if it is below the established limit, can be harmful to health. Besides, carrying out an analysis of various investigations we can conclude that the lead concentration in lipsticks produced in the first world countries is lower than the one in those distributed in the developing countries. As a result, it is suggested the research for new components that can avoid the presence of lead, that are sustainable and don´t constitute potential health risk to users.
