These are derived from brown seaweed and contain calcium alginate, which turns into a sodium alginate gel when it comes in contact with wound fluid. They are available as pads or ropes.
The chemical formula of sodium alginate is (C6H7O6Na)n.

Alginate is a natural polysaccharide derived from brown seaweed. It is composed of guluronic and mannuronic acid monomers linked together to form a gel-like structure. Alginate is commonly used in food and pharmaceutical industries for its gelling, thickening, and stabilizing properties.

In spatulating alginate material, a spatula is used to mix the alginate powder with water in a clean mixing bowl. The spatula is then used to stir and mix the material until a smooth and consistent mixture is achieved, free of any lumps or air bubbles.
Alginate powder is a compound derived from seaweed that is commonly used in the food industry as a gelling agent, thickener, and stabilizer. It is also used in various other industries, including pharmaceuticals, textiles, and cosmetics. When mixed with a liquid containing calcium ions, alginate forms a gel-like substance.
Sodium alginate beads are formed through a process called gelation, where sodium alginate solution is dripped or squirted into a bath of calcium chloride. The calcium ions in the calcium chloride cause the sodium alginate to crosslink and form solid beads. These beads can then be rinsed and used for various applications in food, pharmaceuticals, and other industries.
No, calcium alginate and Aquacel are not the same. Calcium alginate dressings are made of calcium alginate fibers derived from seaweed, which forms a gel when in contact with wound exudate. Aquacel dressings, on the other hand, are composed of carboxymethylcellulose (CMC) and may also contain ionic silver for antimicrobial properties. Both are used in wound care, but they have different compositions and properties.
Water (deionized) dissolves sodium alginate (slow in cold water, faster in hot, but it is not very easy to dissolve, it may take days of constant stirring). Sodium alginate is insoluble in all organic solvents I know about. Alginic acid is insoluble in *anything* (that doesn't react with it chemically).
