The chemical compound calcium acetate is the calcium salt of acetic acid. It has the formula Ca(CH3COO)2.H2O. An alternative formula is Ca(C2H3O2)2. Its standard name is actually calcium ethanoate.
CAS: 62-54-4 (anhydrous) and 5743-26-0 (monohydrate), molar weight 176.18 g/mol, NFPA 1-1-0, no health hazard, appearance White powder, soluble in water, density approx 1.60 kg/l,
Melting point above 160 ¡ãC. When heated above that, it may produce the flammable/explosive acetone.
The anhydrous form is very hygroscopic, therefore the monohydrate is the common form.
If an alcohol is added to a saturated solution of calcium acetate, a semisolid, flammable gel forms that is much like "canned heat" products such as Sterno.
Calcium Acetate is used in a wide variety of different applications. Calcium Acetate is an effective growth inhibitor of certain bacteria. It is widely employed in bread to prevent rope formation thus extending the shelf life of the product. High moisture content of bread encourages the growth of bacteria causing rope. These bacteria are heat resistant and survive at temperatures attained during the backing process. This means that conditions conducive to rope development, adequate measures must be taken to prevent rope formation. Calcium Acetate is an effective anti-rope agent and does not effect the fermentation process, baking results or taste of the bread. Concentration levels of 0.2 ¨C0.5% based on the amount of flour is recommended.
Calcium Acetate also finds its application in the production of resinates for printing inks. Calcium Acetate can be used to increase the milk fat production of dairy cows. Furthermore, it is used in Calcium soap manufacturing, in the production of high temperature lubricating grease and as catalyst for polyester production.
Storage and handling:
Calcium Acetate should be stored and handled in its original packing or in suitable sealed containers and kept in a clean dry place.
Under normal conditions of use, Calcium Acetate does not present any undue health hazard.
Precautions should be taken to prevent entry in the eyes and prolonged or repeated skin contact with the solid or its solutions. Exposure to the dust at high concentrations should be prevented by provision of suitable ventilation.
