Cosmetic Toxicology: Investigating Heavy Metal Contamination in Commercially Sold Make-up Cosmetics in Asaba, Nigeria.

Abstract

This study aims to investigate the presence and concentrations of heavy metals in commonly used make-up cosmetics in Asaba, Southern Nigeria. A total of 50 cosmetic products, including foundation, powder, eyeshadow, eyeliner, and lipstick, were randomly selected from local markets and beauty shops. Atomic Absorption Spectroscopy (AAS) was employed to detect and quantify the levels of lead (Pb), nickel (Ni), cadmium (Cd), and chromium (Cr) in the samples. The results revealed that 70% of the products contained at least one heavy metal, with nickel and chromium being the most detected. In some cases, the levels of these metals exceeded the safe limits established by regulatory agencies, posing potential health risks to consumers. This study underscores the need for more stringent regulations and consistent monitoring of cosmetic products in Nigeria to prevent exposure to toxic heavy metals. It also highlights the importance of consumer awareness and education regarding the safe use of cosmetics.
