As such, some persons may develop mild reactions that may be attributed to sensitivities or allergies in certain individuals. Occasionally, it has been linked with some skin reactions such as rashes or wheezing. Also, there are some controversies about benzene production, for which there are certain level of public concern.
This is a carcinogenic compound that is found when sodium benzoate reacts with ascorbic acid, for instance, due to exposure to heat or light. However, in actual storage operations, the levels are closely regulated and are considerably lower than those that are considered to be hazardous.
