| solubility | Potassium alginate is soluble in water, dissolving to form a viscous hydrophilic colloidal solution. It is insoluble in ethanol (95%) and in hydroalcoholic solutions in which the alcohol content is greater than 30% by weight; also insoluble in chloroform, ether, and acids having a pH lower than about 3. When preparing solutions of potassium alginate it is important to ensure proper dispersion of the particles, as poor dispersion will lead to the formation of large lumps of unhydrated powder and significantly extended hydration times. |

POTASSIUM ALGINATE Chemical Properties,Uses,Production
Chemical Properties
Potassium alginate occurs as a white to yellowish, fibrous or granular powder; it is almost odorless and tasteless.
Uses
Potassium Alginate is a gum that is the potassium salt of alginic acid. It is soluble in cold water, forming a viscous colloidal solution. It functions as a stabilizer, thickener, and gelling agent. It is used in dietetic foods, low-sodium foods, dry mixes, and dental impression material. Typical usage levels range from 0.05 to 0.50%.
Production Methods
Alginate obtained from brown seaweed is subjected to demineralization, extraction, and precipitation of alginic acid. Following neutralization, the potassium alginate obtained is dried and milled.
Definition
Hydrophilic colloid having a molecular weight of 32,000–250,000.
Pharmaceutical Applications
Potassium alginate is widely used in foods as a stabilizer, thickener, and emulsifier; however, its use as a pharmaceutical excipient is currently limited to experimental hydrogel systems. The viscosity, adhesiveness, elasticity, stiffness, and cohesiveness of potassium alginate hydrogels have been determined and compared with values from a range of other hydrogel-forming materials.The effect of calcium ions on the rheological properties of procyanidin hydrogels containing potassium alginate and intended for oral administration has also been investigated.
Safety
Potassium alginate is widely used in food products. It is currently used as an excipient only in experimental pharmaceutical formulations.
storage
In the solid state, potassium alginate is a stable material that is not
prone to microbial spoilage. Over time, a slow reduction in the
degree of polymerization can occur, which may be reflected in a
reduction in the viscosity of solutions. As both temperature and
moisture can impair the performance of potassium alginate, storage
below 25°C is recommended.
Potassium alginate solutions are stable at pH 4–10; long-term
storage outside this range can result in depolymerization of the
polymer through hydrolysis. Gelation or precipitation of the
alginate can occur at pH values less than 4. Liquid or semisolid
alginate formulations should be preserved: suitable preservatives
are sodium benzoate, potassium sorbate, or parabens.
Potassium alginate should be stored under cool, dry conditions
in a well-closed container.
Incompatibilities
Incompatible with strong oxidizers.
Regulatory Status
GRAS listed. Accepted for use in foods in the USA and Europe.
