Ingestion of high doses has been linked to decreased body weight gain, food consumption, and thyroid weight in rats.
- Why here
- This ingredient is used as an antioxidant in food packaging, leading to potential, albeit low-level, dietary exposure through migration into food.
- What would have to be true
- Repeated oral exposure above 135 mg/kg body weight/day, based on animal studies. The U.S. EPA's reference dose (RfD) for repeated oral exposure is 1.35 mg/kg/day.
- The other side
- The U.S. EPA has established a reference dose (RfD) of 1.35 mg/kg/day for repeated oral exposure, and the substance is exempt from tolerance requirements for certain uses in pesticide formulations on food, indicating that typical exposure levels are not expected to pose a risk. The FDA also lists it as an indirect food additive for specific uses in food contact materials.
