The algae is then treated with an acidic solution to help disrupt cell walls, which converts the alginate salts into insoluble alginic acid; a subsequently applied alkaline solution (pH 9-10), usually sodium carbonate, converts it back into water-soluble sodium alginate, which is then precipitated.

The name derives from the Greek words tragos (meaning "goat") and akantha ("thorn"). Iran is the biggest producer of this gum. Gum tragacanth is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides obtained from sap that is drained from the root of the plant and dried. The gum seeps from the plant in twisted ribbons or ...
Seaweed is used in the production of textiles: a water-soluble fiber known as alginate is produced and is used as a holding fiber; when the cloth is finished, the alginate is dissolved, leaving an open area. Rayon is a manufactured fiber derived from plant pulp. [97] Different types of rayon can imitate feel and texture of silk, cotton, wool ...
[5] [6] MonoSol is one of the companies that develops the water-soluble film used for laundry and dishwasher detergent packs, used by brands including Tide, with roughly US$250 million in annual sales and controlling around 90-percent of the market. [7] Notable brands of these packs include All, Arm & Hammer, Gain, Purex, Persil, Rinso and Tide ...
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.
The final product is a dispersion of polymer particles in water. It can also be known as a polymer colloid, a latex, or commonly and inaccurately as an 'emulsion'. Smith-Ewart theory does not predict the specific polymerization behavior when the monomer is somewhat water-soluble, like methyl methacrylate or vinyl acetate.
Bloated food packaging doesn’t always mean the food inside is dangerous to eat, says Zhang. If you live in a high-altitude area, such as Denver, a food package may swell because the air pressure ...
Systemic (absorbable) antacids: They are water soluble and systemically absorbed and pass into the bloodstream. e.g. sodium bicarbonate or sodium citrate; Non-systemic (non-absorbable) antacids: They are insoluble and not absorbed into systemic circulation. They only act in the stomach e.g. magnesium carbonate or calcium carbonate [14]
