What it is + why it's regulated

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.
