The Libyan Centre for Chemical Analysis has issued a warning to women regarding the daily use of cosmetics, emphasising the critical need to avoid kohl and tattoo pencils, particularly those of unknown origin.
The Centre clarified that traditional kohl contains high levels of heavy metals, especially lead, which can cause serious health effects. It specifically advised mothers against using it on infants due to their heightened sensitivity.
These warnings are based on a new research paper titled: “Estimation of Heavy Metal Levels (Lead, Cadmium, and Zinc) in Samples of Raw, Commercial, and Traditional Kohl Sold in Libya.” This study was conducted in collaboration between a research team from Sebha University and the Libyan Centre for Chemical Analysis.
The study’s findings revealed alarmingly high levels of lead in traditional kohl samples, with some exceeding 10,000 micrograms per gram—a concentration far surpassing the safe limits recommended by the World Health Organization.
Cadmium and zinc were also detected in all product types analysed, with some commercial eyeliners and tattoo products exceeding permissible limits for harmful substances.
Overall, the results showed that samples of raw, commercial, and traditional kohl contained the highest concentrations of most metals examined, particularly lead.
The study further noted that the use of traditional kohl on infants raises grave health concerns due to their potential exposure to high and dangerous levels of lead through skin absorption or ingestion.
The study underscored the urgent need to enhance regulatory oversight and increase public awareness regarding the risks of heavy metal contamination in products. It stressed the necessity for regulatory bodies to conduct regular periodic tests on all cosmetic products circulated in the markets, aiming to detect harmful products and prevent their distribution, especially those lacking quality marks or verifiable sources.
