Collection: Semisynthetic Polymers

Semisynthetic Polymers — collects semisynthetic polymers derived from cellulose, such as methyl cellulose with various viscosity levels in aqueous solution. Chemical modification of this natural cellulose chain produces polymers with adjustable gelling and thickening properties.

Semisynthetic Polymers such as methyl cellulose are used in drug delivery system (DDS) research as controlled-release matrices, film-forming agents, and thickeners in dosage form formulations. Pharmaceutics and materials science researchers select a specific viscosity grade to adjust the release rate of the active substance or the rheological characteristics of the formulation being developed.

Example products in this collection: TCI M0295 9004-67-5 Methyl Cellulose (7000-10000mPa.s, 2% in Water at 20deg C), TCI C0045 9004-32-4 Carboxymethyl Cellulose Sodium Salt (n=approx. 500), TCI M0294 9004-67-5 Methyl Cellulose (1000-1800mPa.s, 2% in Water at 20deg C), TCI C0603 9004-32-4 Carboxymethyl Cellulose Sodium Salt (n=approx. 1,050), TCI M0293 9004-67-5 Methyl Cellulose (350-550mPa.s, 2% in Water at 20deg C), TCI C3250 39422-83-8 Carboxymethyldextran Sodium Salt (Mw.=ca. 10000), TCI M0292 9004-67-5 Methyl Cellulose (80-120mPa.s, 2% in Water at 20deg C), TCI C3251 39422-83-8 Carboxymethyldextran Sodium Salt (Mw.=ca. 40000).

Select the grade according to the viscosity of the 2% solution required by the formulation, because each grade gives different thickening and gel-forming characteristics. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
