Potassium bromate is a chemical substance often used as a flour treatment agent to strengthen dough and improve the texture of baked goods. It is also found in some cosmetics and as a laboratory reagent. The International Agency for Research on Cancer (IARC), part of the World Health Organization, has classified potassium bromate as Group 2B, meaning it is possibly carcinogenic to humans. This classification is based on studies in animals that showed an increased risk of cancer, though evidence in humans is limited. Because of this, many countries regulate or restrict its use in food products to reduce potential health risks. While it is not banned everywhere, consumers may see it listed in ingredient labels on breads or pastries. This summary draws on public regulatory data; the linked source is authoritative.
Potassium bromate is a chemical substance that is banned from use in cosmetic products sold in the European Union. It is listed in Annex II of the EU Cosmetics Regulation, which means it cannot be added to any cosmetic formulation. This substance is sometimes used as a flour improver in baking, but in cosmetics it is prohibited because of safety concerns. The European Union's scientific committee has determined that potassium bromate may pose risks to human health, and it is classified as a potential carcinogen by international bodies. Because of these risks, regulators have decided it should not be present in products like lotions, soaps, or makeup. The ban helps ensure that cosmetics sold in the EU are safe for consumers.
