Magnesium sulfate (medical use) ionic strength prevents some of the temporary skin wrinkling (partial maceration) which is caused by prolonged immersion of extremities in pure water. Magnesium and sulfate ions are naturally present in some mineral waters. The claimed health benefits of Epsom Salt baths have not been proven. A magnesium sulphate paste is also available which is claimed to be useful for small boils or localised infections. The standard British Pharmacopoeia composition is dried Magnesium Sulfate 47.76 % w/w, Phenol 0.49 % w/w. and glycerol (E422). Magnesium sulfate has been used as an experimental treatment of Irukandji syndrome caused by envenomation by certain
Magnesium perchlorate He sold the magnesium perchlorate to A. H. Thomas Co., now Thomas Scientific, under the trade name Dehydrite. It is used as desiccant to dry gas or air samples, but is no longer advised, for use as a general desiccant, due to hazards inherent in perchlorates. It is dried by heating at 220 °C under vacuum. Magnesium perchlorate is created by the reaction of magnesium hydroxide and perchloric acid. In 2011, a study conducted at the Georgia Institute of Technology revealed the presence of magnesium perchlorate on the planet Mars. Being a drying agent, magnesium perchlorate retains water from the
