CAS 9005-38-3: Sodium alginate

Sodium alginate is a natural polysaccharide that is extracted from seaweed and used as an emulsifier, thickener, and stabilizer in food products. It is also used to create a gel with water or other liquids. The viscosity of sodium alginate can be modified by adding sugar, glycosylation, or methylation. Click modification is used to introduce fluorine atoms into the polymer backbone. Sodium alginate may be modified by adding oligosaccharides or monosaccharides for use as a bio-sorbent in wastewater treatment plants.

A gelling polysaccharide extracted from giant brown seaweed, useful in viscosity studiesAlginic acid sodium salt is widely utilized in food industry as flavorless gum, which enhances viscosity and as an emulsifier. It finds application as thickener for reactive dyestuffs, which is used in textile screen printing and carpet jet-printing. It is used indigestion tablets and the preparation of dental impressions. As a polymer, it combines with chitosan to synthesize a biodegradable porous scaffold, which is useful for tissue engineering applications. It acts as a food additive and involved in the production of gel-like foods such as bakers. It is employed as thickener for reactive dyestuffs in textile screen-printing and carpet jet-printing. It is also used as encapsulating agents of microparticles of beta-galactosidae and in the preparation of alginate hydrogels with tunable mechanical properties. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

It is a hematologic agent, drug that acts on blood and blood-forming organs and those that affect the hemostatic system. sodium alginate has been used in warp sizing, packing and printing. In printing, it is an ideal kind of material with wide applications in the cotton, wool, silk and synthetic fiber. Sodium alginate is widely used in food industry such as it is the main material of seaweed, synthetic grape and synthetic cherry, it is taken as a stabilizer of ice cream and ice cream bar because of its dense organization and slow solution speed. It is also the main material of the dainty cold powder and jelly, As a stabilizer of cake (such as cookies, bread, fine dried noodle, chocolates) and a polish of bread, sodium alginate can keep the cookies sweet-smelling and avoid falling to pieces, and make the noodle smooth and reduce breaking ratio of noodle and fragmentation of bread. Sodium alginate is also a good thickener of jam, chili sauce, jelly, tomato ketchup, fishpaste, pudding and salad flavoring.

Sodium alginate is the sodium salt of a polysaccharide obtained from brown seaweeds. The main use for alginate is in textile printing as a thickener in the printing of cottons with reactive dyes. In the food industry it is used as a thickener and gelling agent. The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG).

Sodium alginate is a soluble fiber that is extracted from brown seaweed. It is a natural carbohydrate that can be modified to create a variety of sugar-based derivatives, such as Oligosaccharides, Monosaccharides, and Custom Synthesis. Sodium alginate has been modified with Fluorination, Methylation, Glycosylation, and Click Modification to create high-purity products for various applications.

Sodium alginate-Low Viscosity

Sodium alginate is a biocompatible polymer that is used in the treatment of wastewater. It is a water-soluble substance that forms a viscous solution when dissolved in water. Sodium alginate has been shown to inhibit the growth of bacteria and fungi, as well as to reduce the number of coliforms and other microorganisms in water. The potential for an alginate to be biocompatible depends on its chemical structure, with Laminaria Hyperborea being the most biocompatible. Alginates have been shown to have surface properties that are similar to those of natural tissue, making them useful for wound dressings.

Sodium salt of a polysaccharide obtained from the brown seaweeds (e.g. Laminaria hyperborea, Fucus vesiculosus, Ascophyllum nodosum). The chemical structure consists of blocks of (1,4) linked-β-D-polymannuronic acid (poly M), (1,4) linked-α-L-polyguluronic acid (poly G) and alternating blocks of the two uronic acids (poly MG). Alginates form strong gels with divalent metal cations and the egg box model has been used to describe this form of gelation. The main use for alginate is in textile printing as a thickener in the printing of cottons with reactive dyes. In the food industry it is used as a thickener and gelling agent.  Recently, it has been shown that ternary mixtures of Konjac glucomannan, Xanthan gum and Sodium alginate can form a non-covalently linked complex which exhibits enhanced rheological properties of value in, for example, functional foods.
