Many people are unaware of the hidden dangers lurking within their everyday clothing¹. The fabrics and materials used to create synthetic garments often contain a cocktail of potentially toxic chemicals that can be readily absorbed through the skin.
While these synthetic fibers may boast enticing features like wrinkle resistance and moisture-wicking capabilities, the reality is that they come at a significant cost to human health. One of the most concerning substances commonly found in these garments is formaldehyde, a potent preservative used to provide a crisp, fresh-from-the-store appearance. However, formaldehyde is classified as a known carcinogen and has been linked to a host of adverse health effects, including skin irritation, respiratory problems, and even increased cancer risk with prolonged exposure. Beyond formaldehyde, synthetic textiles may also be treated with a variety of other hazardous substances, such as flame retardants, dyes, and stain-resistant coatings, all of which can seep into the skin and accumulate in the body over time. This is particularly concerning given that many people wear these garments for extended periods, maximizing their exposure to these toxic chemicals. While the convenience and affordability of synthetic fabrics may be tempting, consumers would be wise to carefully consider the hidden health costs and seek out more natural, organic clothing options whenever possible. After all, what good is a wrinkle-free shirt if it's slowly poisoning you from the inside out? These chemicals were not designed with the intention of causing negative health effects; however, do their intended uses overshadow their potential harmful consequences? Let us examine this matter.²
Flame retardants are engineered to prevent the ignition of clothing and are mandated for use in children's apparel. However, this beneficial technology has been associated with health risks due to bioaccumulation, which refers to the accumulation of chemicals in the bloodstream, leading to potential issues such as infertility, neurotoxicity, endocrine disruption, and cancer.³
Phthalates are utilized in activewear, anti-odor apparel, printing inks, and various processing applications. As plasticizers, they are combined with rubber to transfer images onto clothing, and they are primarily recognized for their carcinogenic properties. Additionally, phthalates have been associated with endocrine disruption.
PFAS substances are fluoropolymer coatings and products valued for their resistance to water, oil, heat, and stains. These materials are commonly utilized in items such as raincoats, footwear, cosmetics, mattress pads, and various textiles, including both natural and synthetic fabrics, which are marketed as water- or stain-repellent. However, these chemicals have inadvertently escaped from their intended applications, contaminating our environment, drinking water, and food supplies. Consequently, they are known to bioaccumulate and are frequently identified as environmentally persistent and potentially carcinogenic.
Chlorine bleach, known for its whitening and stain removal properties, poses significant risks for asthma and respiratory issues. It is commonly utilized in the treatment of natural fibers like cotton, including denim, and in the preparation of polyester for dyeing. Both chlorine bleach and solvents like chlorobenzenes can be hazardous through inhalation or skin exposure.
Lead and Chromium (VI) are heavy metals that exist in various forms and are present in rocks, plants, animals, and soil. Lead can be found in natural fibers like cotton, hemp, and flax. In manufacturing, Lead and Chromium (VI) are utilized to enhance color stability during dyeing. These elements are often present in brightly colored synthetic products. Although they occur naturally, elevated concentrations of these substances can lead to skin absorption or ingestion, which have been associated with cancer and contact dermatitis. Furthermore, washing clothing that contains these compounds, both during production and by consumers, can result in environmental harm.
During the manufacturing process, the use of solvents, adhesives, plastic and metal components, synthetic dyes, and fibers results in the emission of volatile organic compounds (VOCs). Notable examples of these VOCs include formaldehyde, toluene, ethylene glycol, benzene, methylene chloride, 1,3-butadiene, xylene, and tetrachloroethylene. While these substances contribute to the creation of low-maintenance finishes, such as wrinkle-resistant products, they pose significant occupational risks. The off-gassing of VOCs can lead to serious health issues, including damage to the developmental and reproductive systems, as well as skin and eye irritation, and complications affecting the liver and respiratory system.
Azo dyes constitute 60-70% of textile colorants, contributing to the vibrant hues observed in various fabrics, particularly those with black and brown tones. These dyes can easily leach from materials and, upon skin contact, decompose to emit aromatic amines, which may lead to skin allergies and dermatitis, with certain compounds linked to cancer.
