Common Harmful Chemicals in Hair Chalk
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.
Resorcinol is a white crystalline compound with various uses in areas like tanning, photography, resin manufacture, adhesives, and cosmetics. It can be used medically as an antifungal, antibacterial, and keratolytic agent, and in dermatology-related treatments, specifically for acne amongst others. Direct skin contact with the compound can cause redness, itching, dermatitis, and even corrosion of the affected area. Overexposure could lead to symptoms like irritation, dermatitis, dyspnea, drowsiness, hypothermia, and changes to spleen, kidney, and liver. Animal studies have shown that high oral doses can result in fatalities whereas smaller doses can cause changes to liver weights with no reported carcinogenic effect or mutations in Salmonella typhimurium strains.
Talc, a naturally occurring mineral, is commonly used in cosmetics and personal care products for its moisture-absorbing, smoothing, and anti-caking properties. It is also utilized in food products and animal feed. However, some talc may be contaminated with asbestos fibers, which are linked to cancer. This contamination occurs due to the proximity of talc deposits to asbestos mining sites. Health concerns associated with talc include irritation, cancer risks, and potential organ system toxicity.
