Description
Potassium alginate
CAS No:.9005-36-1
Molecular Formula:(C6H7KO6)n
Appearance:White or ligjt yellow powder.
Uses: Potassium alginate is widely used in foods as a stabilizer, thickener, and emulsifier.
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.
