what are the risks of potassium or sodium benzoate (commonly found as preservatives)?

See below: Very little. The drug is used in medicine to assist in lowering serum ammonia levels by activation of a nonurea cycle pathway; ammonia in the presence of benzoate will conjugate with glycine to form hippurate which is secreted by the kidney. As a preservative, there is little worry unless the individual is also on probenecid which can inhibit benzoate renal excretion.
