In today's discussions about chemicals in industry and commerce, it is increasingly common to see diverse substances grouped together under broad labels, often without regard for their individual properties, uses, or safety profiles. While such categorizations may simplify complex issues, they can also obscure important scientific distinctions. Recognizing the unique characteristics of individual substances, and addressing them appropriately, is important to promoting both public confidence and effective policymaking.
Bisphenol A (BPA) is a “building block,” behind-the-scenes chemistry used primarily in producing polycarbonate plastics and epoxy resins. These materials are highly valued by product manufacturers for their durability, clarity, and resistance to heat and impact, and they help enable many of the devices and technologies we rely on every day.
BPA is one of the most thoroughly tested chemicals used today, extensively studied by regulatory agencies and scientific bodies around the world. These evaluations have consistently supported the conclusion that BPA is safe as currently used, particularly in applications such as food contact materials.
This extensive body of scientific research provides a strong foundation for understanding BPA's safety profile. But importantly as well, it also shows why chemical evaluations should be based on the specific data available for each substance rather than broad assumptions about entire categories of materials. Scientifically sound and risk-based regulatory decisions should reflect the available evidence, real-world exposure conditions, and how a particular substance is used.
When different substances – even those within the same chemical class – are treated as interchangeable, fundamental differences between chemistries, their performance, potential exposure pathways, depth of safety research, and actual risks can be overlooked. Such oversimplification can create undue confusion and alarm among the public and policymakers alike, making it more difficult to distinguish between substances with different toxicological profiles, regulatory histories, and roles in modern society.
Essential Uses that Enhance Safety and Sustainability
BPA-based materials play a critical role in applications that directly contribute to safety and quality of life. Epoxy resins made with BPA are used as protective coatings inside food and beverage cans, helping to prevent contamination and food spoilage. Without these linings, the shelf life of many foods would be significantly reduced, increasing food waste and potentially compromising food safety.
Similarly, BPA-based polycarbonate plastics are integral to medical devices, safety equipment, infrastructure, electronics, and transportation applications. Their unique combination of strength, durability, heat resistance, and transparency makes them well suited for products that people rely on every day. In many of these applications, BPA contributes performance characteristics that can be challenging to replicate without introducing tradeoffs in durability, efficiency, safety, cost, or environmental performance.
Maintaining access to well-studied, high-performing materials is essential for sustaining innovation and competitiveness. Policies that do not adequately account for the scientific evidence for individual substances, such as BPA’s especially long record of safe use, can lead to unintended consequences, including supply chain disruptions, higher costs, product unavailability, and reduced competitiveness for U.S. manufacturers.
Using risk-based decision-making, backed by sound science, is genuinely important, and it should be the goal. As conversations about chemicals continue to evolve, it is important that policies remain grounded in sound science, real research, and risk-based evaluation. BPA's extensive scientific database, long history of safe use, and role in critical applications demonstrate the value of assessing substances individually, based on both hazard and real-world exposure.
The bottom line is that BPA should be evaluated according to its own scientific record. Decades of research, regulatory review, and real-world data provide a substantial body of evidence supporting its safety. By recognizing BPA as a well-used and extensively studied chemistry, policymakers can support innovation, maintain high safety standards, and strengthen America's position as a leader in advanced materials.
