Industry Grade
Alginic acid absorbs moisture quickly and can be used as a dehydrating and sizing agent in the paper and textile industries. Its main function is to use it as an emulsifier or thickener in the food industry and the daily chemical industry in the form of sodium alginate or potassium alginate. It is a common ingredient in foods and cosmetics such as ice cream and milkshake.

Medicine Grade
In the pharmaceutical industry, alginic acid is a commonly used excipient: its viscosity makes it a binder for tablets; because it swells with water, it is used as a disintegrant to disperse tablets in the human body; or The dispersing agent disperses the active ingredient into the liquid to form a suspension; the alginate is used as a drug sustained release agent. It is used in dentistry to replace plaster and rubber to make dental molds. Alginic acid itself can be used as an absorbent to treat heavy metal poisoning.
