Natural Polymers

Natural Polymers — covers natural polysaccharides and biopolymers such as alkali lignin, amylopectin from waxy corn, sodium alginate, xylan, xanthan, and gum arabic extracted from plant or microbial sources. The diversity of sugar chain structures and functional groups determines the viscosity, gel-forming, and binding properties for each application.

These natural polymers are used by food, pharmaceutical, and materials researchers to formulate binders, thickeners, gelling agents, and emulsion stabilizers in various colloidal systems. Sodium alginate and xanthan gum are commonly used in hydrogel development and encapsulation research, while alkali lignin and xylan serve as raw materials for research on renewable materials based on lignocellulosic biomass.

Example products in this collection: TCI L0082 8061-51-6 Lignin (Alkaline), TCI C0072 1398-61-4 Chitin, TCI A0456 9037-22-3 Amylopectin (Amylose free), from Waxy Corn, TCI C0335 9082-07-9 Chondroitin Sulfate Sodium Salt, TCI A0205 9005-38-3 Sodium Alginate 100-200, TCI C0831 9012-76-4 Chitosan (200-600mPas, 05% in 05% Acetic Acid at 20deg C), TCI X0078 9014-63-5 Xylan from Corn Core, TCI C1804 11114-20-8 kappa-Carrageenan.

Pay attention to the botanical or microbial source of the raw material, the solution viscosity grade, powder particle size, and purity levels such as amylose-free content or solvent residues, as these affect the consistency of functional properties. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
