Formaldehyde: this is a colorless, odorless chemical commonly used by manufacturers in building materials, household products, and textiles. High exposure to this compound can lead to numerous reactions, including skin irritation and certain types of cancer.
Heavy Metals: these are elements with high density that can be found in clothing with dyes and synthetic fibers. Repeated exposure to these substances can be absorbed through the skin, leading to factors such as abdominal pain, arrythmia, and kidney/liver damage.
Organotins: commonly used in pesticides, pollutants, and even found in some textiles, these are chemical compounds present in synthesized materials. Their neurotoxic properties can lead to endocrine disruption, fertility issues, and hormonal imbalance.
Phthalates: a group of chemicals used in plastics to make them more durable and flexible, often called plasticizers. Oftentimes, they're in textiles, personal care products, and especially leggings, sometimes resulting in respiratory issues and metabolic disorders.
Perfluorinated Chemicals (PFCs): a class of hazardous substances widely utilized in a range of products including household cleaners, textiles, and adhesives. Lately, they have been attracting significant attention because of their adverse effects, which may include reduced immunity and certain types of cancer.
