Ortho-Phthalates: The Plasticizers Lurking in Your Polish
What are Ortho-Phthalates?
Ortho-phthalates, often simply referred to as phthalates, are a group of chemicals used primarily as plasticizers. They make materials like plastics more flexible and durable. In the context of nail salons, ortho-phthalates are frequently found in nail polish and other nail care products. Ortho-phthalates are commonly added to nail polish to enhance flexibility, prevent cracking, and give the product a smooth application. The most well-known of these is dibutyl phthalate (DBP), a plasticizer that’s long been a staple in many nail polish formulas.
Health Risks
Ortho-phthalates are linked to several health concerns, particularly in reproductive health. Exposure to these chemicals has been associated with hormonal disruptions, developmental issues in children, and even increased risks of infertility. Phthalates can also affect the endocrine system, leading to a host of long-term health problems. Workers in nail salons who are consistently exposed to phthalates through inhalation and skin contact are particularly at risk. (1-3)
Organophosphate Esters (OPEs): Flame Retardants and More
What are Organophosphate Esters (OPEs)?
OPEs are a group of chemicals commonly used as flame retardants and plasticizers. While they are primarily used in industrial applications, they are also found in consumer products, including those used in nail salons. In nail salons, OPEs can be present in various nail polish removers, adhesives, and other products that require plasticizing agents. Although they are less commonly discussed compared to phthalates, their presence in these products adds to the cumulative chemical burden in salon environments.
Health Risks
OPEs are neurotoxic, meaning they can adversely affect brain and nerve function. Chronic exposure has been linked to cognitive impairments, memory problems, and developmental delays in children. In addition, OPEs can disrupt hormone levels and are suspected of contributing to reproductive harm. For nail salon workers, prolonged exposure can increase the likelihood of these health issues.

Triphenyl Phosphate (TPhP): The Hidden Risk in Nail Polish
What is Triphenyl Phosphate (TPhP)?
Triphenyl phosphate, or TPhP, is a chemical used as a plasticizer and flame retardant. It has gained attention as a replacement for certain banned phthalates, but it carries its health risks. TPhP is often found in nail polishes, particularly in products marketed as “non-toxic” or “phthalate-free.” While it’s used to improve the durability and flexibility of polish, it’s essentially another plasticizer with concerning health implications.
Health Risks
TPhP is known to be an endocrine disruptor, interfering with hormone function and potentially leading to reproductive issues, metabolic disorders, and even developmental problems. Some studies suggest that exposure to TPhP may contribute to obesity and other metabolic conditions. Given that nail technicians handle these products daily, they are at an elevated risk for these health effects. (6-8)
Conclusion
While exact safe exposure limits for these chemicals in Canada may not always be explicitly defined, the key is to minimize exposure and adhere to best practices informed by both Canadian and international guidelines. Nail salons should prioritize high-quality ventilation, regular air monitoring, and the use of safer, non-toxic products to ensure the health and safety of workers and clients.
