Collection: Natural Polymers (for DDS)

Natural Polymers (for DDS) — gathers natural polymers such as polysaccharides and proteins and their semisynthetic derivatives used as carrier materials in drug delivery systems (DDS). This group includes polysaccharides from plants, animals, and microbes, along with their chemical modifications that alter solubility and gel-forming properties.

Natural Polymers (for DDS) are used by pharmaceutical and formulation researchers to make hydrogel matrices, microcapsules, or coating layers that control the release of active ingredients in a controlled manner. Polysaccharides such as alginate and chitin are often used to form ionic gel networks, while semisynthetic derivatives such as carboxymethyl cellulose are chosen for their adjustable solubility and viscosity, and proteins such as albumin or casein are used as microparticle-forming materials in formulation research.

Example products in this collection: TCI A0205 9005-38-3 Sodium Alginate 100-200, TCI C0045 9004-32-4 Carboxymethyl Cellulose Sodium Salt (n=approx. 500), TCI A0198 Albumin from Dried Egg White, crude, TCI C0072 1398-61-4 Chitin, TCI X0078 9014-63-5 Xylan from Corn Core, TCI C0335 9082-07-9 Chondroitin Sulfate Sodium Salt, TCI A3553 9000-01-5 Gum Arabic, TCI C0594 9005-46-3 Casein Sodium from Milk.

Pay attention to the degree of substitution and molecular weight for semisynthetic polymers, as well as the source and solution viscosity for natural polymers, since these determine gelation properties and active ingredient release performance in formulations. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.

Other categories at the same level under Drug Delivery Systems (DDS), often used together in one laboratory workflow:

• Monomers for Synthetic Polymers (for DDS)
• Prodrug Ingredients
• Chelating Agents (for DDS)
• Cyclodextrins (for DDS)
• Drug Delivery Systems (DDS) Research Reagents (Others)

This collection is further divided into 1 more specific group:

• Semisynthetic Polymers
