CAS:Food additive, applied in pharmaceuticals and beauty products.
Pureza:Min. 90%Cor e Forma:White PowderCarboxymethyl-dextran sodium salt - Average MW 150,000
CAS:Sodium carboxymethyl dextran (CM-dextran) is a white, odourless and tasteless powder, which is freely soluble in water or electrolyte solutions. The product has a pronounced polyanionic character, due to the high degree of carboxyl substitution. Applications that have been described for CM-dextran include carriers of paramagnetic contrast agents, preparation of conjugates of pharmacologically active compounds and CM-dextrans in biosensors. A number of other uses in cosmetics, agriculture, foods, paints and textiles have been the subject of patent applications.Cor e Forma:White PowderCompression wood galactan

CAS:Cellulose derivative, food thickener and emulsifier, bulk forming laxativeCor e Forma:PowderPolydextrose
CAS:Polydextrose is a synthetic polymer of glucose. It is a food ingredient classified as soluble fibre by the U.S. Food and Drug Administration (FDA) as well as Health Canada, as of April 2013. It is frequently used to increase the non-dietary fibre content of food, to replace sugar, and to reduce calories and fat content. It is a multi-purpose food ingredient synthesized from dextrose (glucose), plus about 10 percent sorbitol and 1 percent citric acid. Its E number is E1200. It was approved by FDA in 1981.Pureza:Min. 95%Cor e Forma:PowderDextran 70 - MW 64,000 to 76,000
CAS:Dextran is α-(1,6)-linked α-D-glucan with α-(1,3)-linked glucose branch points produced by fermentation of Leuconostoc mesenteroides via the action of the enzyme dextransucrase on sucrose. The main use for native dextran is as an extender in blood transfusions and products having a range of sharp cut-off molecular weights are produced commercially for this and other applications. A complex of Iiron with dextran, known as iron dextran, is used as a source of iron for baby piglets which are often anaemic at birth.Cor e Forma:White Off-White PowderInulin - from chicory
CAS:Inulin is a prebiotic dietary fibre with a mildly sweet taste that promotes digestive health by supporting growth of healthy and balanced microbiota. In diagnostics, inulin is used for determining the glomerular filtration rate in functional kidney testing. Chemically, inulin is a chain of fructose molecules terminated at the reducing end with glucose. Thus, inulin is a fructan consisting of linear chains of β-(2,1) linked fructose residues, terminated at the reducing end by an α-D-(1,2)-glucopyranoside moiety. It has a degree of polymerization typically between 2 and 60 (5). The β-(2,1) bond in inulin resists digestion in the gastrointestinal tract and is therefore responsible for its lower caloric value and beneficial effects on colon microbiota. A more functional form of inulin is produced by removing all fractions with chain lengths lower than 10.Pureza:(Uv) Min. 95%Cor e Forma:White PowderAlginic acid
CAS:A linear polyuronide obtained from the brown seaweeds (e.g. Laminaria hyperborea, Fucus vesiculosus, Ascophyllum nodosum). In the free acid form, the chemical structure consists of protonated 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).Cor e Forma:PowderCorn starch
CAS:Starch is a two component polysaccharide mixture of amylose and amylopectin. Amylose is a linear polysaccharide of α (1,4)-linked glucose residues and averages 20 to 30% of the total in most native starches. Amylopectin is a highly branced glucan containing both a (1,4) and a (1,6) linkages. The number of glucose residues in a single starch molecule can vary from five hundred to several hundred thousand, depending on the type of starch. Starch is the major storage form of energy in plants, just as glycogen is the storage form of energy for animals. The plant directs the starch molecules to the amyloplasts, where they are deposited to form granules. Thus, both in plants and in the extracted concentrate, starch exists as granules varying in diameter from 2 to 130 μm.Pureza:Min. 95%Cor e Forma:PowderCarboxymethyl-dextran sodium salt - Average MW 20,000

CAS:Hyaluronic acid is a polysaccharide composed of repeating units of the disaccharide N-acetylglucosamine and D-glucuronic acid. It is found in many connective tissues, including the skin, where it binds water and maintains elasticity. This product is custom synthesized by modifying the structure to include fluorine atoms, methyl groups, and monosaccharides. It is synthesized from synthetic building blocks that are modified with click chemistry to form oligosaccharides. The saccharide units are then glycosylated with sugar molecules, creating a complex carbohydrate with an average molecular weight between 50,000 and 100,000 Daltons.
Pureza:(%) Min. 90%Hydroxypropyl cellulose - Average MW 150,000
CAS:In water, hydroxypropyl cellulose forms liquid crystals with many mesophases depending on concentration. These mesophases include isotropic, anisotropic, nematic and cholesteric, the latter resulting in many colors such as violet, green and red. Pharmaceutical applications include treatments for medical conditions such as dry eye syndrome (keratoconjunctivitis sicca), recurrent corneal erosions, decreased corneal sensitivity, exposure and neuroparalytic keratitis. It is also used as a binder in tablets. Hydroxypropylcellulose is also used as a thickener, a binder and emulsion stabiliser in foods with E number E463. HPC is used as a support matrix for DNA separations by capillary and microchip electrophoresis.
