Common Harmful Chemicals in Lip Stain
Chemical Name
Why it’s harmful
Mica, a natural mineral dust, is commonly used in makeup, cement, asphalt, and electric cable insulation. It is a color additive in cosmetics and provides a shimmer effect in foundations. Workers exposed to mica, especially in muscovite mills, face health risks like respiratory problems and lung scarring from long-term inhalation. Labels may list "Mica" or "Muscovite." Regulatory agencies have established exposure limits for worker safety.
Pentaerythrityl Adipate/Caprate/Caprylate/Heptanoate is a mixed ester compound derived from pentaerythritol and various acids such as adipic, capric, caprylic, and heptanoic acids. This ingredient is commonly found in products like lipstick, foundation, blush, bronzer/highlighter, and lip balm.
Calcium aluminum borosilicate, a glass-type material, serves as a bulking agent in the cosmetics and personal care industry. It enhances volume and texture in formulations, generally considered safe with low toxicity and no known cancer-causing properties. Although it's generally safe, individual sensitivities can differ, so patch tests are recommended for those with allergies. Regulatory classification includes a possibility of being carcinogenic and possibly toxic to reproduction, but it is deemed safe for cosmetic use, with concentration or use restrictions.
Tocopheryl acetate is a compound composed of acetic acid and tocopherol (vitamin E). Alpha-tocopheryl acetate (ATA), a specific form of vitamin E, is commonly found in skincare products and dietary supplements. It is used in various cosmetics and personal care items, including lipstick, eye shadow, blushers, face powders, moisturizers, bath soaps, hair conditioners, and more.
BHT, a toluene-based ingredient, serves as a preservative in food and personal care products. Safety assessments have noted toxic effects in lung tissue when BHT was applied to rats' skin but considered the low concentrations in cosmetics safe. The American Conference of Governmental Industrial Hygienists (ACGIH) suggests moderate evidence of BHT being a respiratory irritant in humans.
