This blog is part of a series on chemical ingredients that are commonly used in consumer products.\u202f\u202f<\/em><\/p>\n\n\n\n

Bisphenol A (BPA) is a widely used chemical in plastic and resin manufacturing. Prized for its utility in consumer goods, BPA is also known to interfere with the body\u2019s endocrine system. Still used today in some food packaging, plastic containers, and receipts, BPA\u2019s long-term impacts are still being studied.<\/p>\n\n\n\n

BPA is among the many chemicals we prohibit in Green Seal-certified product packaging\u202fto ensure products meet a high standard for protecting people and the planet.<\/p>\n\n\n\n

Here, we’ll delve into how BPA functions, how you might be exposed to it, and how to reduce your risk of exposure to this hazardous chemical.<\/p>\n\n\n\n

What Is Bisphenol A?<\/h2>\n\n\n\n

Bisphenol A is a synthetic compound primarily used to produce polycarbonate plastics and epoxy resins. These materials are known for their strength, clarity, and resistance to heat and impact, and are used to make water bottles and food storage containers, among many other products.<\/p>\n\n\n\n

BPA is classified as an endocrine disruptor \u2014 a chemical that can interfere with the body\u2019s hormone system. BPA closely resembles estrogen, a hormone that regulates many biological processes. Because of this similarity, BPA can bind to estrogen receptors and either mimic or block the hormone\u2019s normal activity. This can overstimulate hormonal pathways and interfere with normal hormone signaling, leading to developmental changes.<\/p>\n\n\n\n

Invented over a century ago, BPA is produced en masse today. In fact, millions of tons are produced annually. Its widespread presence in consumer products and its effects on the human body have made it one of the most studied chemicals of the modern era.<\/p>\n\n\n\n

BPA in Consumer Products<\/h2>\n\n\n\n

BPA can be found in everyday products both as a product feature and as a result of the product\u2019s packaging. It\u2019s commonly found in:<\/p>\n\n\n\n

    \n
  • Polycarbonate plastics
    Used in reusable water bottles, cleaning product bottles, food storage containers and eyewear.<\/li>\n\n\n\n
  • Epoxy resin linings
    Coatings on the inside of paint cans and canned foods and beverages, designed to prevent corrosion and contamination.<\/li>\n\n\n\n
  • Thermal paper
    Used in receipts, tickets, and labels due to BPA\u2019s ability to act as a heat-sensitive developer, although BPA is slowly being phased out of these materials.<\/li>\n<\/ul>\n\n\n\n

    BPA can leach from containers into everyday products \u2014 especially when plastics are heated or deteriorating \u2014 or be absorbed through the skin after handling items such as receipts. As a result, nearly all people tested in national biomonitoring studies show some level of BPA in their bodies.<\/p>\n\n\n\n

    Health Risks of BPA<\/h2>\n\n\n\n

    Scientific studies link BPA to a range of health effects, including:<\/p>\n\n\n\n

      \n
    • Reproductive disorders<\/li>\n\n\n\n
    • Neurodevelopmental delays<\/li>\n\n\n\n
    • Immune system dysfunction<\/li>\n\n\n\n
    • Increased risk of hormone-related cancers<\/li>\n<\/ul>\n\n\n\n

      Some studies also suggest a possible link between BPA exposure and health conditions including obesity, diabetes, and cardiovascular disease.<\/p>\n\n\n\n

      The U.S. Food and Drug Administration maintains that BPA is safe at the very low levels found in some foods, though it banned the chemical in baby bottles and sippy cups and continues to review emerging evidence. However, several U.S. states have enacted bans on BPA in food-contact materials. Meanwhile, the European Food Safety Authority took a very strict stance in 2023, lowering the tolerable daily intake of BPA by 20,000-fold \u2014 from 4 micrograms per kilogram of body weight per day to just 0.2 nanograms \u2014 based on a large body of new evidence linking even low-level exposure to possible effects on the immune system, hormone regulation, and development.<\/p>\n\n\n\n

      Many brands have already shifted toward \u201cBPA-free\u201d alternatives, often in response to consumer demand rather than regulatory mandates.<\/p>\n\n\n\n

      Reducing BPA Exposure<\/h2>\n\n\n\n

      Unfortunately, avoiding the health impacts associated with BPA isn\u2019t as simple as looking for products with BPA-free marketing claims. Because Bisphenol A has earned a bad reputation with consumers, many manufacturers have replaced it with other bisphenols like Bisphenol S or Bisphenol F that have a lower public profile but are linked to similar health concerns.<\/p>\n\n\n\n

      The good news is that being aware of products that may contain BPA and being careful how you use them can help you avoid exposure:<\/p>\n\n\n\n

        \n
      • Avoid microwaving or heating food in plastic containers<\/li>\n\n\n\n
      • Choose fresh or frozen foods instead of canned, when possible<\/li>\n\n\n\n
      • Look for glass, stainless steel or silicone containers and water bottles<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
