HPMC（ヒドロキシプロピルメチルセルロース） そして HEC（ヒドロキシエチルセルロース） are the primary cellulose ethers used as tablet binders in solid dosage form manufacturing. HPMC is the most widely used grade, providing excellent binding efficiency, consistent tablet hardness, and controlled disintegration in both direct compression and wet granulation processes. HEC is used in selected formulations requiring specific compression or disintegration profiles.
Binding · Hardness · Disintegration
Tablet binders are among the most critical excipients in solid dosage form manufacturing. They determine tablet cohesion, mechanical integrity, disintegration behavior, and ultimately the dissolution and release profile of the active pharmaceutical ingredient (API). Selecting the right binder — and the right grade — directly affects tablet quality, process reproducibility, and regulatory compliance.

Excellent binding efficiency for wet granulation and direct compression
HPMC（ヒドロキシプロピルメチルセルロース） is the most widely used cellulose ether binder in pharmaceutical tablet manufacturing. Available in multiple viscosity grades, it allows formulators to select the appropriate binding strength and disintegration control. Lower viscosity grades are preferred for direct compression and immediate release; higher viscosity grades for wet granulation and modified release.
Low to medium viscosity grades for specialty tablet formulations
HEC（ヒドロキシエチルセルロース） is used in selected tablet formulations where specific compression characteristics, disintegration profiles, or compatibility requirements make it a suitable alternative or complement to HPMC. Low to medium viscosity HEC grades are typically considered for these applications.
Different formulation types and manufacturing processes require different cellulose ether viscosity directions and performance priorities.

HPMC and HEC support cohesion between API particles, fillers, and other powder components during both granulation and compression. Effective binding reduces friability, improves tablet integrity, and supports consistent tablet weight and dimensions across production batches.
Cellulose ether binders enhance tablet hardness and resistance to physical damage during handling, packaging, and transport. The right grade and concentration combination ensures tablets meet hardness specifications without compromising disintegration or dissolution.
The viscosity grade and concentration of HPMC or HEC directly influence how quickly a tablet disintegrates after administration. Lower viscosity grades support faster disintegration for immediate release; higher grades slow disintegration for modified or extended release.
In wet granulation, HPMC dissolved in the granulation liquid provides the binding solution that promotes granule nucleation and growth. Consistent binder solution concentration and addition rate are critical for uniform granule size distribution.
The binder system contributes to overall dissolution behavior. In immediate release, the binder should not significantly retard dissolution. In modified release, HPMC at higher concentrations creates a hydrophilic matrix controlling drug release through swelling and erosion.
LANDERCOLL HPMC and HEC grades are compatible with high-shear wet granulation, fluid bed granulation, roller compaction, and direct compression. Consistent particle size distribution supports reliable process performance.
When tablet quality issues arise during development or production, binder grade, viscosity, and concentration are often the first variables to review.
Low binder concentration or inadequate grade for the formulation system.
Increase HPMC or HEC content, or select a higher viscosity grade for improved cohesion.
Poor binding or insufficient cohesion during compression and elastic recovery.
Use an appropriate cellulose ether grade for improved inter-particle bonding and tablet integrity.
Variable binder efficiency or granulation inconsistency across batches.
Ensure consistent HPMC/HEC grade, concentration, and granulation process parameters.
Too high viscosity or excessive binder concentration retarding breakup.
Adjust grade or reduce concentration; consider lower viscosity HEC or HPMC.
Too low viscosity or insufficient binder level for the target release profile.
Adjust grade or concentration to achieve target disintegration time.
Insufficient binder solution concentration or inconsistent liquid addition.
Optimize binder concentration and granulation liquid addition rate for uniform granules.
Inappropriate binder grade or concentration relative to dissolution target.
Review grade selection and concentration relative to target dissolution profile.

HPMC (Hydroxypropyl Methylcellulose) is the most widely used cellulose ether for tablet binder applications. It provides excellent binding efficiency, consistent hardness, and controlled disintegration in both direct compression and wet granulation processes. HEC (Hydroxyethyl Cellulose) is used in selected formulations requiring specific compression or disintegration profiles.
HPMC is the primary choice for tablet binding due to its broad applicability, strong binding efficiency, and well-established regulatory acceptance across immediate and modified release formulations. HEC is used in selected applications where specific compression characteristics or disintegration profiles are required. Both are listed in major pharmacopoeias.
Yes. The viscosity grade and concentration of HPMC or HEC directly influence disintegration time and dissolution behavior. Lower viscosity grades at lower concentrations generally support faster disintegration for immediate release tablets. Higher viscosity grades at higher concentrations can slow dissolution, useful for modified or extended release formulations.
Typical dosage ranges from 2% to 10% w/w depending on formulation type and process. Direct compression tablets typically use 2%–6%, wet granulation tablets 3%–8%, and modified release tablets 5%–10%. Final dosage should always be confirmed through laboratory formulation and compression trials.
Yes. HPMC and HEC are broadly compatible with most common tablet excipients including fillers such as microcrystalline cellulose and lactose, disintegrants such as croscarmellose sodium and sodium starch glycolate, lubricants such as magnesium stearate, and most APIs. Compatibility should always be confirmed through formulation testing.
