アルギン酸カリウム 化学特性,用途語,生産方法

• 定義

  本品は、アルギン酸(*)のカリウム塩である。参照表示名称：アルギン酸

• 化粧品の成分用途

  結合剤、親水性増粘剤、乳化安定剤

• 化学的特性

  Potassium alginate occurs as a white to yellowish, fibrous or granular powder; it is almost odorless and tasteless.

• 使用

  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%.

• 定義

  Hydrophilic colloid having a molecular weight of 32,000–250,000.

• 調製方法

  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.

• 応用例（製薬）

  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.

• 安全性

  Potassium alginate is widely used in food products. It is currently used as an excipient only in experimental pharmaceutical formulations.

• 貯蔵

  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.

• 不和合性

  Incompatible with strong oxidizers.

• 規制状況(Regulatory Status)

  GRAS listed. Accepted for use in foods in the USA and Europe.
