Potassium alginate is obtained by reacting alginic acid extracted from deep-sea algal plants such as kelp and ascophyllum nodosum with potassium carbonate or potassium hydroxide. The product appears as a white to pale yellow amorphous powder, odorless and tasteless, easily soluble in water to form a viscous solution.
1> Molecular Formula: (C₆H₇O₆K)ₙ
2> Calculated Equivalent Weight: 214.22
3> Actual Average Equivalent Weight: 238.00
4> Relative Molecular Weight: 32,000 ~ 250,000
Mainly used as an impression material, beer foam stabilizer, and can also be used in the coating of welding electrodes. Potassium alginate has excellent hydrophilicity, fluidity, thickening properties, and gelling properties.
1> Cosmetics: A key component of mask bases.
2> Dental Films: A primary ingredient in dental impression materials, enabling the formed dental mold to have a smooth surface for easy peeling and mold removal.
3> Pharmaceuticals & Health Products: Possesses functions such as reducing blood lipids, blood glucose, and cholesterol.
4> Industrial Welding Materials: Used as a binder in high-end industrial welding electrodes, ensuring the electrode coating is smooth and free of pores.
