Product Details

Instant-dissolving grade HPMC utilizes a special surface treatment technology, enabling rapid dispersion in cold water without clumping, forming a uniform and transparent solution. Its dissolution speed is several times fasfontter than that of ordinary HPMC, significantly enhancing production and construction efficiency, making it particularly suitable for industrial and cosmetic formulations with strict requirements for dissolution speed.

Key Features and Performance

  • Rapid Dissolution: Forms a uniform solution in a short time

  • No Clumping: Excellent dispersibility in cold water

  • High Solution Stability: Maintains the same viscosity and functionality as standard HPMC

  • Time and Cost Savings: Reduces mixing and waiting time

  • Versatility: Suitable for various formulation systems

Main Functions

  • Reduces production and construction preparation time

  • Rapidly establishes system viscosity and structure

  • Maintains system stability and uniformity

Usage Recommendations

  • Viscosity Selection: 40,000–200,000

  • Addition Rate: 0.2%–0.5%

Packaging and storage/transportation precautions

Coated polypropylene woven bags, net weight per bag: 25 kg. Protect from direct sunlight, rain, and moisture during storage and transportation.


Product application

Instant-dissolving hydroxypropyl methylcellulose disperses instantly in cold water and forms a transparent solution, making it ideal for applications requiring extremely fast dissolution.

  • Ready-to-use dry-mixed mortar

Simply add water and stir to achieve rapid and uniform dissolution, reducing waiting time.

  • Chemical formulation production

Used in water-based systems requiring immediate dissolution, such as water-based coatings and adhesives.

  • Cosmetic cold mixing process

Forms a uniform system quickly without heating during production, reducing energy consumption.

  • Pharmaceutical and food industry

Used as an instant thickener or colloidal stabilizer.

  • Water treatment agents

Disperses quickly to achieve uniform mixing.
