ALVARADO Y, Ángel et al. Determination of Plumb in lip pencils of different commercial marks in Lima. Horiz. Med. [online]. 2014, vol.14, n.2, pp.18-21. ISSN 1727-558X.

Objective: To determine the presence of lead in lipsticks from different brands that are sold in the city of Lima. Material and Methods: 24 lipsticks of five different trademarks were used, from the shopping center in Lima Capon. The presence of lead was determined by the method of atomic absorption spectrophotometry with graphite furnace. For statistical validation, the mean and standard deviation was determined. Results: The highest lead content was found in the LAL -04 - YHBC (3.02 ppm) , LAL -05 - BALOE (2.10 ppm) , LAL -02 -RW (1.55 ppm) and LAL -03 marks - VCYH (1.22 ppm ) ; contrasted with a little known brand , LAL -01- CHOCO PLUSII code where no lead was detected . Conclusions: Of the studied lipsticks, four exceeded the permissible values of lead (0.1 ppm), which is a reference value for candy.

Palabras clave : Lead; lipstick; permissible values.
