2. Sodium polyacrylate - Wikipedia

   en.wikipedia.org/wiki/Sodium_polyacrylate

   Finally, water-soluble sodium polyacrylates were obtained by washing and drying the hydrolyzed resultant. This is a different method compared to the manufacturing processes that have been previously utilized, but could be a potential method to specifically manufacture sodium polyacrylate.

3. Alginic acid - Wikipedia

   The algae is then treated with an acidic solution to help disrupt cell walls, which converts the alginate salts into insoluble alginic acid; a subsequently applied alkaline solution (pH 9-10), usually sodium carbonate, converts it back into water-soluble sodium alginate, which is then precipitated.

4. Hydrogel - Wikipedia

   en.wikipedia.org/wiki/Hydrogel

   Alginate hydrogels are formed by ionic interactions between alginate and double-charged cations. A salt, usually calcium chloride, is dissolved into an aqueous sodium alginate solution, that causes the calcium ions to create ionic bonds between alginate chains. [27] Gelatin hydrogels are formed by temperature change. A water solution of gelatin ...

5. Calcium alginate - Wikipedia

   en.wikipedia.org/wiki/Calcium_alginate

   Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.

6. Polyvinyl alcohol - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_alcohol

   Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH 2 CH(OH)] n. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless.

7. Solubility chart - Wikipedia

   en.wikipedia.org/wiki/Solubility_chart

   The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

9. Alginate dressing - Wikipedia

   en.wikipedia.org/wiki/Alginate_dressing

   Alginate is initially extracted from the cell wall of brown seaweeds. Alginate dressings can be in the form of freeze-dried, porous (foam) sheets or flexible fibres. Flexible fibres are used to treat cavity wounds. The alginate will form a gel in contact with the exudates of the wound and give it a strong absorbent power. [2]
