Advanced Chemical Engineering
& Molecular Precision

Redefining stability and efficiency through high-purity cationic cellulose derivatives.

As a global leader in the manufacturing of specialty cellulose ethers, our cationic cellulose stands as a benchmark for pharmaceutical and construction grade additives. By utilizing a proprietary etherification process with controlled substitution levels, we ensure that our products possess the ideal hydrophilic-lipophilic balance, enabling unmatched compatibility with diverse active ingredients and substrates.

The technical superiority of our cationic cellulose lies in its rapid swelling capacity and high internal porosity. This unique structure facilitates faster disintegration rates in pharmaceutical tablets and enhances the moisture-retention properties in construction materials, providing a critical advantage in both bioavailability enhancement and structural longevity.

The Three Core Pillars

Our manufacturing excellence is built upon three foundational technological strengths.

01

Molecular Precision

Strict control over the hydroxypropyl substitution levels to ensure predictable performance.

  • ▪Substitution Range: Optimized between 5.0% to 16.0% for specific grades.
  • ▪Purity Levels: Pharmaceutical grade purity with negligible heavy metal content.
  • ▪pH Stability: Maintained between 5.0-7.5 for maximum drug compatibility.
02

Structural Integrity

Engineered porosity that allows for rapid liquid absorption and swelling.

  • ▪Swelling Rate: Significantly outperforms standard starch disintegrants.
  • ▪Mosaic Effect: Rough structural profile for enhanced drug bonding.
  • ▪Dispersion: Ensures fine dispersion after rapid tablet disintegration.
03

Scalable Quality

Industrial-scale production without compromising pharmaceutical-grade specs.

  • ▪Precision Particle size control (e.g., ≥106μm or ≤75μm).
  • ▪Advanced spray drying and milling technologies.
  • ▪Stringent batch-to-batch consistency verification.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

01

What is the primary difference between LH-20 and LH-22?

The main difference lies in the hydroxypropoxyl content. LH-20 has a higher substitution (13-16%), which typically results in different swelling and binding characteristics compared to the lower substitution LH-22 (7-9.9%).

02

How does cationic cellulose improve tablet disintegration?

It creates a high-porosity internal structure that absorbs water rapidly. The resulting internal pressure causes the tablet to burst more efficiently than traditional starch-based agents.

03

Is your product compatible with all pH values?

Yes, our cationic cellulose is a non-ionic compound, meaning its properties are largely unaffected by the pH value of gastric or intestinal fluids, ensuring stability in diverse environments.

04

What is the recommended dosage for wet granulation?

For use as a tablet adhesive in wet granulation, the general dosage ranges from 2% to 20%, depending on the specific formulation and required hardness.

05

How should the product be stored for long-term stability?

The product should be stored in a cool, dry environment. Our cardboard barrels are lined with polyethylene sealed bags to ensure maximum moisture-proofing.

06

Are your raw materials sustainable?

Yes, we primarily use high-quality refined cellulose from sustainably managed wood pulp and cotton linters to minimize our environmental footprint.
