Uses
Calcium alginate (CAS NO.9005-35-0) is used in Plant tissue culture to produce insoluble artificial seeds. It is also used for immobilizing enzymes by entrapment. Moreover Calcium alginate can be still used to produce an edible substance.
Production
Extraction process of Calcium alginate (CAS NO.9005-35-0): The rationale behind the extraction of alginate from the seaweed is to convert all the alginate salts to the sodium salt, dissolve this in water, and remove the seaweed residue by filtration. Recover alginate from the aqueous solution which is very dilute and evaporation of the water is not economic. To the Sodium alginate from the initial extraction solution, a calcium salt is added. This causes calcium alginate to form with a fibrous texture; it does not dissolve in water and can be separated from it.

Poison by intravenous route. Moderately toxic by intraperitoneal route. When heated to decomposition it emits acrid smoke and irritating fumes.
Specification
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Dangerous fire hazard in the form of dust when exposed to heat or flame.
Extinguishing Media: In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Handling: Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes.
Storage: Store in a cool, dry place. Store in a tightly closed container.
