Pencil eyeliner / kohl — safety profile

What is this product?

Pencil and kohl eyeliners are applied by direct drawing on the eyelid and waterline, creating prolonged skin contact and potential eye exposure. The formulation is anhydrous with wax and oil bases (petroleum-derived paraffin or plant-based carnauba wax) and carbon black or iron oxides as colorants. Legacy kohl products may contain lead (historically common in South Asian and Middle Eastern formulations). Modern formulations use safer colorants but the waterline application and potential leaching remain a concern for sensitive eyes.
