HPMC, CMC e HEC são os éteres de celulose primários usados como excipientes farmacêuticos. HPMC é o mais versátil — suportando compressão de comprimidos, revestimento de filmes, matrizes de liberação controlada, filmes orais e aplicações em cápsulas. CMC é comumente usado para controle de viscosidade, estabilidade de suspensão e sistemas líquidos orais ou oftálmicos selecionados. HEC may be used in selected water-based systems for thickening and stabilization. Final polymer type, grade, and concentration must be confirmed through formulation testing and documentation review.
Binding · Coating · Release Control
Pharmaceutical excipients play an essential role in dosage form design. They support manufacturability, stability, appearance, release behavior, patient acceptability, and product consistency. In many solid, semi-solid, and liquid dosage forms, cellulose ethers are used because they can provide binding, film formation, viscosity control, gel formation, suspension stability, and controlled-release support.
LANDERCOLL fornece adequado HPMC, CMC, HEC, and selected cellulose ether grades for pharmaceutical excipient applications. These products can be used in tablets, capsules, coatings, controlled-release systems, oral films, ophthalmic formulations, suspensions, gels, and other selected dosage forms.
A suitable cellulose ether grade helps formulators control powder cohesion, solution viscosity, coating performance, matrix hydration, suspension behavior, and product texture. Because pharmaceutical applications require strict quality control, grade selection and documentation review are critical before formulation evaluation begins.

In tablet formulations, cellulose ether can help improve powder cohesion, granule strength, tablet hardness, and mechanical integrity — supporting both wet granulation and direct compression processes depending on grade and concentration.
HPMC can form smooth and uniform films for tablet coating and oral film systems. Film quality depends on polymer grade, plasticizer selection, coating process parameters, drying conditions, and overall formulation design.
HPMC can hydrate and form a gel layer in hydrophilic matrix tablets, helping regulate water penetration, API diffusion, and matrix erosion. Viscosity grade and polymer concentration are the primary levers for tuning the release profile.
Cellulose ethers help adjust viscosity in liquid, semi-solid, coating solution, suspension, and gel formulations. Viscosity grade selection is critical for both processability during manufacturing and final product performance.
CMC, HPMC, and selected HEC grades can help suspend dispersed ingredients and reduce sedimentation in selected pharmaceutical systems — including oral suspensions and ophthalmic formulations.
Cellulose ether can improve texture, spreadability, lubrication feel, and product consistency in selected liquids, gels, and semi-solid systems — contributing to patient acceptability and ease of use.
A suitable cellulose ether grade helps maintain predictable hydration, viscosity, and formulation behavior during manufacturing and scale-up — reducing batch-to-batch variability and supporting process validation.
Cellulose ether can help improve many formulation challenges, but final dosage-form performance depends on the complete formulation, API properties, excipient compatibility, manufacturing process, stability profile, and regulatory validation.

HPMC, CMC, and HEC are the primary cellulose ethers used as pharmaceutical excipients. HPMC is the most widely used, covering tablet binding, film coating, controlled-release matrices, oral films, and capsule applications. CMC is commonly used for viscosity control, suspension stability, and selected ophthalmic or oral liquid systems. HEC may be used in selected water-based systems for thickening and stabilization.
HPMC may be used as a tablet binder, film-forming coating polymer, hydrophilic controlled-release matrix former, viscosity modifier in liquid systems, oral film polymer, and selected capsule-related excipient. Its versatility across multiple dosage forms makes it one of the most important pharmaceutical excipients in modern formulation development.
CMC may be used for viscosity control, suspension stability, smooth texture, lubrication feel, and selected oral liquid or ophthalmic systems. It is particularly associated with oral suspension formulations and artificial tear systems where hydration feel and viscosity-building performance are required.
HEC may be used in selected water-based pharmaceutical systems for viscosity control, thickening, stabilization, and texture adjustment. Its non-ionic character makes it useful in systems where ionic sensitivity is a concern. Customer validation and suitable pharmaceutical-grade documentation are required.
Yes. HPMC is widely used in hydrophilic matrix tablets where hydration and gel-layer formation help control drug diffusion and matrix erosion — enabling extended or modified-release profiles. Final release performance must be confirmed through dissolution testing and validated according to the target regulatory pathway.
Yes. Suitable cellulose ether grades — particularly HPMC — can support binding, cohesion, and tablet mechanical strength in selected tablet formulations, both in wet granulation and direct compression processes.
No. Pharmaceutical applications require suitable pharmaceutical-grade cellulose ether that meets recognized pharmacopoeia standards (USP/NF, Ph. Eur., ChP) and is supported by appropriate quality documentation. Industrial or food-grade materials do not meet the purity, safety, and documentation requirements for pharmaceutical dosage forms.
