Potassium bromate CAS#7758-01-2

Potassium bromate is the potassium salt of bromate. It is typically used in the United States as a flour improver. It acts to strengthen the dough and to allow higher rising. Potassium bromate (KBrO3) is an oxidizing agent that has been used as a food additive, mainly in the bread-making process. However, it has been realized that it is a potential carcinogenic agent. The agent is carcinogenic in rats and nephrotoxic in both man and experimental animals when given orally. It has been demonstrated that KBrO3 induces renal cell tumors, mesotheliomas of the peritoneum, and follicular cell tumors of the thyroid. In addition, experiments aimed at elucidating the mode of carcinogenic action have revealed that KBrO3 is a complete carcinogen, possessing both initiating and promoting activities for rat renal tumorigenesis.

Product Application Of Potassium bromate CAS#7758-01-2

Potassium bromate (KBrO3) is used primarily as a maturing agent for flour and as a dough conditioner. It is recognised as one of the best dough conditioners in the bakery industry. Scientific evidence surfaced in 1990, implicating bromate as a possible carcinogen. In response to the potential hazards, the United Nations Joint Food and Agricultural Organisation and the World Heath Organisation decided to revoke potassium bromide from the list of acceptable flour treatment additives.
As nonfood usage, KBrO3 has been introduced as an oxidizing agent, a primary standard, and a brominating agent in analytical chemistry. Its oxidizing property has further been used in home permanent-wave neutralizing compounds at concentrations of between 5 to 25% at pH 4 to 9, together with sodium bromate, sodium perborate, or hydrogen peroxide.
