Potassium Bromate is commonly found in our food & personal care products.  But we should avoid it. Why?

Carcinogenicity: The International Agency for Research on Cancer (IARC) classifies it as Group 2B (possibly carcinogenic to humans), with links to kidney, thyroid, and gastrointestinal cancers in animal studies.
Dermal Absorption: While typically poorly absorbed through healthy skin, the Cosmetic Ingredient Review (CIR) Expert Panel recommends it not exceed 10.17% in hair formulations to minimize risk.
Acute Toxicity: If ingested, it can cause severe symptoms, including abdominal pain, vomiting, kidney failure, and permanent hearing loss.
Organ Damage: Repeated exposure can lead to nervous system effects, such as headaches and impaired thinking, as well as chronic kidney damage.
