ADI:
NOT SPECIFIED
Comments:
The Committee concluded that there are no differences in the evaluation of the toxicity of magnesium stearate compared with other magnesium salts and confirmed the ADI “not specified” for magnesium salts of stearic and palmitic acids.
Intake:
Potential total dietary exposure to magnesium stearate of 44 mg/kg bw per day for children and 83 mg/kg bw per day for adults, corresponding to 2 and 4 mg/kg bw per day expressed as magnesium, respectively. This would contribute up to an additional 240 mg/day to the background exposure to magnesium from food of 180–480 mg/day. The Committee noted that the consumption of the food additive may lead to an additional dietary exposure to stearic and palmitic acids in the order of
5 g/day.
