why choose keyong for customization
At Keyong, we know that every project has unique requirements. That’s why we go beyond standard solutions to deliver tailor-made HPMC formulas designed specifically for your application needs. Our mission is to deliver the most suitable HPMC solution for your product’s functional and economic requirements.
Flexible Formula Development
We tailor HPMC grades to meet your performance targets, adjusting key parameters such as: Viscosity levels; Water retention; Gelation behavior; Dissolution rate; Our R&D team works closely with your technical team to ensure the custom formulation aligns with your product specifications and performance outcomes
Viscosity Control – Tailored Rheology for Every Application
Viscosity determines the thickening efficiency, water retention, and workability of HPMC in your formulation.
Keyoung offers a full viscosity range from 50 to 200,000 mPa·s (2% solution, 20°C), adjustable to match your processing and product requirements.
Key Features:
- Low-viscosity grades: Ideal for liquid detergents, shampoos, and coatings that need easy flow and dispersion.
- Medium-viscosity grades: Suitable for plasters, body washes, and cosmetic creams.
- High-viscosity grades: Best for tile adhesives, wall putty, and self-leveling mortars requiring strong water retention and open time.
- Custom rheological curve design to balance mixing, spreading, and stability performance.
Substitution Degree Adjustment – Balancing Water Retention and Solubility
The degree of substitution (DS) defines the balance between hydrophilicity, solubility, and gelation of HPMC.
We can adjust the ratio of Methoxy (19–30%) and Hydroxypropyl (4–12%) groups according to your functional needs.
Key Effects of Custom Substitution:
- Higher methoxy → stronger film formation & faster gelling
- Higher hydroxypropyl → better solubility & flexibility
- Controlled DS improves compatibility with cement, surfactants, or polymers in your formulation
- Enables tailored drying time, slip resistance, and water-holding capacity
Particle Size & Moisture Control – Ensuring Smooth Dispersion
The particle size distribution of HPMC influences its dispersion rate, dissolution behavior, and dusting level during processing.
Keyoung provides custom sieving and milling to achieve consistent powder behavior and minimal lumping in water.
Available Options:
- Fine mesh (80–120 mesh): Rapid hydration and quick viscosity build-up for detergents and cosmetics
- Medium mesh (40–80 mesh): Balanced dissolution for coatings and wall putty
- Coarse mesh (<40 mesh): Controlled hydration for cement-based products
Moisture Content:
Maintained below 5%, ensuring stable storage, consistent viscosity, and no clumping in humid conditions.
Gel Temperature Modification – Optimizing Performance Under Different Conditions
Gel temperature (Tg) defines when HPMC transitions from solution to gel form — a critical property in detergent, coating, and construction formulations.
Keyoung can modify this temperature range between 60°C and 90°C depending on your production and end-use requirements.
Customization Benefits:
- Lower gel temperature (60–70°C): Enhances stability and film formation for detergents, shampoos, and water-based coatings.
- Medium gel temperature (70–80°C): Ensures smooth application in tile adhesives, plasters, and wall putty.
- Higher gel temperature (80–90°C): Improves performance in high-temperature mixing and drying processes.

Our Customization Process
Step 1
Requirement Consultation
We begin by understanding your product application, target viscosity, solubility system, and operating temperature.
Our technical team collects detailed data to design the right modification path for your custom HPMC.
Step 2
Formula Design & Material Selection
Our R&D engineers select appropriate cellulose sources, etherification agents, and reaction conditions based on your needs.
At this stage, we define the methoxy/hydroxypropyl ratios and molecular weight distribution to ensure optimal functionality.
Step 3
Laboratory Sample Development
We prepare small-batch HPMC samples (1–5 kg) for testing and evaluation.
This phase ensures the customized formula performs as expected under your processing and end-use conditions.
Step 4
Performance Testing & Adjustment
We collaborate with your technical team to perform compatibility and performance testing.
If adjustments are needed, we fine-tune the substitution level, particle size, or moisture to ensure perfect alignment with your system.
Step 5
Industrial-Scale Production
Once the sample is approved, production shifts to large-scale synthesis and drying lines.
Keyoung’s automated control systems guarantee consistent quality, viscosity accuracy, and moisture uniformity for every batch.
Step 6
Quality Assurance & Global Delivery
Every batch undergoes comprehensive QC — testing viscosity, moisture, pH, substitution degree, and gel temperature.
We provide full documentation, COA reports, and offer global packaging and delivery support.
