Description of combinace
Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.
“Alginate” is the term usually used for the salts of alginic acid, but it can also refer to all the derivatives of alginic acid and alginic acid itself; in some publications the term “algin” is used instead of alginate. Alginate is present in the cell walls of brown algae as the calcium, magnesium and sodium salts of alginic acid.

What is Calcium Alginate?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Calcium Alginate which has developed particularly rapidly in recent years. Do you know about Calcium Alginate ?
- The official answer：White to light yellowish-brown fibrous powder or coarse powder. Almost odorless and tasteless. Insoluble in water, organic solvents. Difficult to dissolve in ethanol. Slowly soluble in sodium polyphosphate, sodium carbonate solution, and solution of calcium compounds. Calcium alginate is the calcium salt of alginate, which is produced from seaweed plants, such as Sargassum, kombu, and kelp, which are quite abundant in our country. The alginate used in the paper industry is mainly the sodium salt or ammonium salt of alginate. The main role of calcium alginate has the following three aspects: (1) calcium alginate sponge: calcium alginate is mainly used in the production of calcium alginate sponge, which can be used to stop bleeding from skin injuries and traumatic bleeding. After the calcium alginate sponge is applied to the wound, it exchanges with the sodium and calcium ions in the exudate and blood of the wound, releasing calcium ions and forming a thin layer of gel on the surface of the wound. Due to the release of calcium ions, the formation of blood clots in the capillary ends is accelerated, thus achieving rapid hemostasis. Due to the formation of the gel layer on the surface of the wound, it plays a certain protective role for the wound, and keeps the wound surface at a certain humidity and temperature, creating a good microenvironment for the healing of the wound and promoting the early healing of the wound. (2) Stabilizer and gelling agent: The ability and strength of sodium alginate to form gel is related to Ca2+. It interacts with calcium ions in cow’s milk to form calcium alginate thus causing a series of complex reactions in milk protein. Calcium alginate can maintain the morphology of ice cream well, especially for long-term preservation, and is very effective in preventing shrinkage and tissue grittiness. It has a synergistic effect with Ca2+ and pectin. (3) Brewer’s yeast immobilization fermentation: Brewer’s yeast is put into sodium alginate solution dissolved with wort, and then dropped into calcium chloride solution dissolved with wort to form calcium alginate particles containing yeast cells, which immobilize yeast cells.
What’s the application of Calcium Alginate?
It is a chemical substance whose role is to be used as stabilizer; thickener; emulsifier; gelling agent. Uses Mainly used in medicine, food additives, welding electrode fluxes, etc.
