E529 - Calcium oxide

Additive: E529 - Calcium oxide

Calcium oxide -CaO-, commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, quicklime specifically applies to the single chemical compound calcium oxide. Calcium oxide that survives processing without reacting in building products such as cement is called free lime.Quicklime is relatively inexpensive. Both it and a chemical derivative -calcium hydroxide, of which quicklime is the base anhydride- are important commodity chemicals. - Wikipedia

Names: Oxyde de calcium, chaux vive
