Kohl containing lead (and other toxic elements) is widely available in Europe

Kohl is an eye cosmetic that was traditionally used in many Asian and African countries but that is now more widely available. Ingredients of kohl reported in previous studies seem to be rather variable but mention is frequently made of minerals based on Pb whose use in cosmetic products is prohibited in Europe. We purchased 23 products of kohl from retail outlets in five different European countries and over the internet and analysed their chemical composition by XRF and SEM-EDXS. The majority of the products (n = 17) did not conform with European legislation based on the presence of Pb (often as galena), whose concentrations ranged from a few mg kg^-1 to over 400000 mg kg^-1. Cadmium, another element prohibited in cosmetic products in Europe, was also present as a contaminant in 13 products at concentrations up to a few hundred mg kg^-1. In addition to heavy metals, minerals of other metals (e.g. Fe and Zn) appeared to be present in the nano-size range and might represent an additional health hazard. Clearly, the lack of quality control in the manufacture of kohl results in the widespread occurrence of toxic and unwanted elements and the trade of illegal products in Europe. In principle, shop sales would be relatively straightforward to prevent, but products traded through internet are more difficult to regulate.

Toxic effect of Cadmium found in eyeliner to the eye of a 21 year old Saudi woman: A case report

PURPOSE

To raise the issue of increased use of traditional medicine while the Tertiary care hospitals are available to provide the appropriate care for each clinical condition. Eyeliner (Kohl) is an Arabic word denoting a fine powder with a texture and appearance similar to mascara. It is usually worn on the lid margins or inside the conjunctival sac by Middle and Far Eastern and in East Africans populations for different purposes like beauty or religious and as a treatment for many eye diseases.

SUMMARY

We report a case of a lady who put traditional locally prepared eyeliner in her eye that resulted in severe corneal edema and faint scaring. On toxicology analysis it was discovered to contain toxic levels of Cadmium (Cd) and Lead (Pb).

CONCLUSION

Cd is a heavy toxic metal like Pb but has never been reported as a component of eyeliners. The most likely possible cause of the corneal clinical picture in our case is due to the toxic effect of Cd found in the traditional eyeliner (Kohl) used in Saudi Arabia.
