Rice Starch-Based Coated Pellets are pharmaceutical excipient-based multiparticulate pellets formulated using rice starch as a principal pellet-forming component and subsequently processed with a suitable coating system. Rice starch is a carbohydrate-based pharmaceutical excipient, and its pelletized form can provide a spherical platform for further coating, layering and formulation development.
Rice starch is primarily composed of starch polymer and is represented by CAS 9005-25-8 with the polymeric formula (C₆H₁₀O₅)n. Because it is a polymeric material, it does not have a single fixed molecular weight.
Commercial rice starch pellet products provide useful finished-pellet reference parameters. One pharmaceutical rice starch pellet specification reports ≥98.0% starch content, ≤5.0% moisture, ≤0.5% ash, pH 5.0–7.0, particle size 0.30–1.50 mm and bulk density 0.40–0.60 g/mL. These values should be treated as a commercial reference and not automatically as SDP's own COA specification.
The coating system, coating weight gain and coating thickness for Rice Starch-Based Coated Pellets are formulation-specific. They should be selected according to the intended pharmaceutical application and confirmed against the applicable finished-product specification.
Rice Starch-Based Coated Pellets can be considered for:
The final characteristics depend on the rice starch content, pellet-core composition, coating material, coating level, particle size and manufacturing process.
A commercial rice starch pellet reference reports a 0.30–1.50 mm particle-size range, 0.40–0.60 g/mL bulk density, ≤5.0% moisture and ≥98.0% starch content.
These values should only be published as SDP specifications if they are confirmed by the actual SDP product COA.
Rice Starch-Based Coated Pellets can be supplied for pharmaceutical formulation development and bulk manufacturing requirements. Particle size, rice starch loading, coating system, coating weight gain, packaging configuration and finished-product specifications should be confirmed against the applicable product specification and COA.
