Magnesium chloride formula milk. Because magnesium is a mobile nutrient, magnesium chloride can be effectively used as a substitute for magnesium sulfate (Epsom salt) to help correct magnesium deficiency in plants via foliar feeding. The recommended dose of magnesium chloride is smaller than the recommended dose of magnesium sulfate (20 g/l). This is due primarily to the chlorine present in magnesium chloride, which can easily reach toxic levels if over-applied or applied too often. It has been found that higher concentrations of magnesium in tomato and some pepper plants can make them more susceptible to disease caused by infection of the bacterium
Magnesium stearate processes. In the creation of pressed candies, magnesium stearate acts as a release agent and it is used to bind sugar in hard candies such as mints. Magnesium stearate is a common ingredient in baby formulas. Magnesium stearate is a major component of "bathtub rings." When produced by soap and hard water, magnesium stearate and calcium stearate both form a white solid insoluble in water, and are collectively known as "soap scum." Magnesium stearate is generally considered safe for human consumption at levels below 2500 mg/kg per day and is classified in the United States as generally recognized as safe
