Abstract

Cosmetics are a mixture of chemical compounds derived from natural or artificial sources, and they 
do not contain environmental pollutants such as heavy metals, which may pose health risk when 
exposed to them. Due to the scarcity of local studies on this topic, in addition to the known toxicity 
of lead (Pb) and cadmium (CD) Especially with daily use, this research was conducted to determine 
the concentration of these two ingredients in facial cosmetics (lipstick, eyeshadow, eyeliner). 
30 samples were collected from the markets of Nalut City, and selected based on color, price, 
country of origin, and source of production. The samples were sent to the Delta Scientific 
Laboratory for analysis using the Atomic Absorber-Graphite Furnace (GF-AAS). 
The results of the analysis showed trace concentrations of lead and cadmium in all samples, and 
were within the limits allowed according to the guidelines of the U.S. FDA,  The World Health 
Organization (WHO), and Health Canada, and  there were significant relation between cosmetic 
type, price and manufacture of lipstick and eyeshadow and lead concentration ,whereas no relation 
between source of kohl production and lead and cadmium concentration. 
Key words: cosmetics ,Heavy metals ,Lead ,cadmium.
