E530 Anti-caking agent

E530 is used for the relief of heartburn and dyspepsia, as an antacid, E530 supplement, and as a short-term laxative. It is also used to improve symptoms of indigestion. Side effects of E530 may include nausea and cramping. In quantities sufficient to obtain a laxative effect, side effects of long-term use include enteroliths resulting in bowel obstruction.

• E530 As a food additive, it is used as an anticaking agent. It is known to the US Food and Drug Administration for cacao products; canned peas; and frozen dessert. It has an E number of E530.
• It was historically used as a reference white color in colorimetry, owing to its good diffusing and reflectivity properties. It may be smoked onto the surface of an opaque material to form an integrating sphere.
• It is used extensively as an electrical insulator in tubular construction heating elements. There are several mesh sizes available and the most commonly used ones are 40 and 80 mesh per the American Foundry Society. The extensive use is due to its high dielectric strength and average thermal conductivity. MgO is usually crushed and compacted with minimal airgaps or voids. The electrical heating industry also experimented with aluminum oxide, but it is not used anymore.
• As a reagent in the installation of the carboxybenzyl (Cbz) group using benzyl chloroformate in EtOAc for the N-protection of amines and amides.
• It is also used as an insulator in heat-resistant electrical cable.
• E530 doping has been shown to effectively inhibit grain growth in ceramics and improve their fracture toughness by transforming the mechanism of crack growth at nanoscale.
