Common Harmful Chemicals in Toothbrush
Chemical Name
Why it’s harmful
Bisphenol A (BPA) is a solid used in manufacturing epoxy resins and polycarbonates for food packaging. Human exposure to BPA can cause allergic dermatitis and has been associated with negative effects on fertility, such as declined semen quality, increased sperm DNA damage, and risk of miscarriage. BPA, an endocrine disruptor, also affects oocyte quality during in vitro fertilization. Animal studies indicate that BPA caused eye damage in rabbits, accelerated tumorigenesis in mice, disrupted sex behaviors in rats, and induced obesity in rodents. Ecotoxicity studies show BPA's disruptive effects on sex characteristics in fish and gene expression in Arabidopsis thaliana, suggesting broad environmental implications.

Phthalates, linked to endocrine disruption, reproductive toxicity, and cancer, are banned in the European Union but remain prevalent in U.S. cosmetics. They are widely used in personal care products, such as nail polish, fragrances, and eyelash glue and other products. A significant loophole allows phthalates to be added to fragrances without disclosure. Health concerns include endocrine disruption, developmental and reproductive toxicity, and potential carcinogenicity.

Formaldehyde is a colorless, flammable gas with a pungent smell that's naturally produced in small quantities in human bodies and is also known as methanal amongst other names. It's used in the production of various items such as fertilizers, paper, plywood, and urea-formaldehyde resins as well as in some foods and household products like antiseptics, medicines, and cosmetics. Exposure to formaldehyde, which can occur through breathing contaminated indoor air, tobacco smoke, or ambient urban air can lead to respiratory symptoms, irritation of the eyes, nose and throat and has been linked to lung and nasopharyngeal cancer as well as leukemia. The EPA considers formaldehyde a probable human carcinogen (Group B1) and inhaling it can cause bronchospasm and pulmonary edema. Commercially, it's sold as formalin in solutions of 37%, 44%, or 50% and long-term exposure can cause first-degree burns, skin sensitization, squamous cell nasal cancer, and chronic pulmonary obstruction.

Vinyl chloride, primarily used in the plastics industry, is a carcinogenic substance linked to liver angiosarcoma and hepatocellular carcinoma. It's been linked to 'vinyl chloride disease', affecting those with long-term occupational exposure, causing bone and neurological conditions, sleep issues, loss of sexual function, and different psychiatric syndromes. Chronic hepatic disorder, categorized as pathologic porphyrinuria, is found in workers suffering from vinyl chloride-induced hepatic injury. Brief exposure to high levels of vinyl chloride has been fatal for rats, guinea pigs, and mice, impairing motor coordination and causing respiratory failure. Other symptoms observed include increased motor activity, twitching of extremities, ataxia, and tremor. Vinyl chloride doesn't cause significant fetal toxicity or teratogenic effects on mice, rats, and rabbits but has shown mutagenic activities on Drosophila melangaster and yeast. It also influenced the regulation of specific genes in Daphnia magna.
Triclosan is a synthetic pesticide with antibacterial properties commonly added to detergents, soaps, and various personal care products such as deodorants and toothpastes. Although it lacks the ability to combat viruses causing colds and flus, it's used in products like body washes, disinfectants, and some toothpastes to resist bacterial growth. In 2016, the FDA limited its use in antibacterial soaps, but the compound is still permitted in other products. The European Union prohibited its presence in food-contact items in 2010. Exposure to triclosan has been associated with hormone disruption, increased breast cancer risk, liver damage, and the development of resistant super-germs.
