POTASSIUM ALGINATE Chemical Properties
| solubility | Potassium alginate is soluble in water, dissolving toform a viscous hydrophilic colloidal solution. It is insoluble inethanol (95%) and in hydroalcoholic solutions in which thealcohol content is greater than 30% by weight; also insoluble inchloroform, ether, and acids having a pH lower than about 3.When preparing solutions of potassium alginate it is importantto ensure proper dispersion of the particles, as poor dispersionwill lead to the formation of large lumps of unhydrated powderand significantly extended hydration times. |
| Odor | at 100.00?%. odorless |
| Cosmetics Ingredients Functions | EMULSION STABILISING VISCOSITY CONTROLLING BINDING |
| InChIKey | LAEKMUKVBJSQBM-CAWKZDFGSA-L |
| EPA Substance Registry System | Alginic acid, potassium salt (9005-36-1) |
Safety Information
| TSCA | TSCA listed |
| HS Code | 3913100000 |
| Hazardous Substances Data | 9005-36-1(Hazardous Substances Data) |
| Chemical Properties | Occurs in filamentous, grainy, granular,and powdered forms. It is colorless or slightly yel-low and may have a slight characteristic smell andtaste. Slowly soluble in water, forming a viscoussolution; insoluble in alcohol. |
| Chemical Properties | Potassium alginate occurs as a white to yellowish, fibrous orgranular 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%. |
| Uses | Thickening agent and stabilizer in dairy prod-ucts, canned fruits, and sausage casings; emulsifier.See alginic acid. |
| Definition | Hydrophilic colloidhaving a molecular weight of 32,000–250,000. |
| Production Methods | Alginate obtained from brown seaweed is subjected to demineralization,extraction, and precipitation of alginic acid. Followingneutralization, the potassium alginate obtained is dried and milled. |
| Pharmaceutical Applications | Potassium alginate is widely used in foods as a stabilizer, thickener,and emulsifier; however, its use as a pharmaceutical excipient iscurrently limited to experimental hydrogel systems. The viscosity,adhesiveness, elasticity, stiffness, and cohesiveness of potassiumalginate hydrogels have been determined and compared with valuesfrom a range of other hydrogel-forming materials.The effect ofcalcium ions on the rheological properties of procyanidin hydrogelscontaining potassium alginate and intended for oral administrationhas also been investigated. |
| Safety | Potassium alginate is widely used in food products. It is currentlyused as an excipient only in experimental pharmaceutical formulations. |
| storage | In the solid state, potassium alginate is a stable material that is notprone to microbial spoilage. Over time, a slow reduction in thedegree of polymerization can occur, which may be reflected in areduction in the viscosity of solutions. As both temperature andmoisture can impair the performance of potassium alginate, storagebelow 25°C is recommended. Potassium alginate solutions are stable at pH 4–10; long-termstorage outside this range can result in depolymerization of thepolymer through hydrolysis. Gelation or precipitation of thealginate can occur at pH values less than 4. Liquid or semisolidalginate formulations should be preserved: suitable preservativesare sodium benzoate, potassium sorbate, or parabens. Potassium alginate should be stored under cool, dry conditionsin a well-closed container. |
| Incompatibilities | Incompatible with strong oxidizers. |
| Regulatory Status | GRAS listed. Accepted for use in foods in the USA and Europe. |
