As a leader in high-performance specialty chemicals, JINJI CHEMICAL develops and manufactures advanced additives critical to modern construction. Our core product range features cellulose ethers — HPMC, MHEC, HEC — which are essential for optimizing water retention, workability and adhesion, as well as for increasing viscosity and thickness in dry-mix mortars (e.g., tile adhesive, wall putty, cement render and self-leveling mortar), detergents and water-based paint.
Complementing these, our Redispersible Polymer Powder (RDP) enhances flexibility and bond strength in cementitious systems. From HPMC for tile adhesive to RDP for mortar, JINJI provides tailored solutions that elevate durability, efficiency, and sustainability across global construction projects — where science meets application mastery.
HPMC (Hydroxypropyl Methyl Cellulose) is a non-ionic, water-soluble polymer derived from natural cellulose through a series of chemical modifications. Its unique molecular structure imparts exceptional thickening, film-forming, water-retention, and rheology-modifying properties — making it indispensable in both construction chemistry and liquid detergent formulation.

JINJI CHEMICAL's flagship cellulose ether and polymer powder products are engineered for precision performance across the most demanding construction and industrial applications.
Superior water retention and workability for smooth, crack-resistant wall finishes on interior and exterior surfaces.
Enhanced thickening and stabilization performance in liquid detergent and spray render formulations.
Redispersible Polymer Powder boosting flexibility, adhesion, and crack resistance in skim coat and tile adhesive systems.
Stable viscosity, anti-separation, and clarity enhancement for household and industrial liquid detergent products.
HPMC's multi-functional chemistry delivers measurable performance improvements across construction and cleaning product applications. Here are the core functional advantages that make JINJI HPMC the preferred choice for formulators worldwide.
Prevents premature drying in wall putty and skim coat, ensuring full cement hydration and eliminating surface cracking or delamination — even in hot, dry climates.
Delivers consistent, adjustable viscosity in both dry-mix construction mortars and liquid detergent systems, enabling smooth application and stable product shelf life.
Improves open time and spreadability of wall putty and skim coat, reducing application fatigue and enabling professional-grade finishes on large surface areas.
Prevents phase separation in liquid detergents, maintains clarity and homogeneity across temperature fluctuations, and enhances the consumer experience with improved texture.
Maintains performance integrity in extreme temperature environments — from Middle Eastern heat to temperate European climates — without viscosity breakdown or product failure.
Derived from natural cellulose, HPMC is biodegradable, non-toxic, and compatible with green building certifications and eco-label detergent standards globally.
Understanding the precise role of HPMC in each application environment allows formulators and contractors to unlock maximum performance. Below is a technical analysis of the three primary application domains.
Wall putty is a white cement-based finishing compound applied to interior and exterior walls prior to painting. In this application, HPMC serves as the primary functional additive. Its water retention capacity — typically 95–99% — prevents the mixing water from being absorbed too rapidly into the substrate, allowing the cement to fully hydrate and develop maximum bond strength.
Typical HPMC dosage in wall putty ranges from 0.2% to 0.5% by weight. The viscosity grade selected (commonly 100,000–200,000 mPa·s) determines the sag resistance and spreadability of the putty. JINJI HPMC grades are specifically optimized for fast dissolution in cold water, ensuring consistent batch-to-batch performance in industrial wall putty production lines.
Skim coat (finish coat or finishing plaster) is a thin, smooth layer applied over rough substrates or existing wall surfaces to create a perfectly level base for decorative coatings. The challenges in skim coat formulation include preventing shrinkage cracks, achieving a mirror-smooth surface, and maintaining adequate open time for large-area application.
HPMC addresses all three challenges simultaneously. Its film-forming properties create a micro-membrane that reduces surface evaporation, while its thixotropic rheology allows easy troweling with anti-sag behavior on vertical surfaces. For gypsum-based skim coats, JINJI's specially modified HPMC grades provide extended open time without compromising final hardness or adhesion to concrete and masonry substrates.
In the liquid detergent industry, HPMC functions as a multifunctional rheology modifier, stabilizer, and film former. Unlike construction applications, detergent-grade HPMC must perform in high-surfactant, high-electrolyte environments where most thickeners fail. HPMC's non-ionic nature makes it compatible with both anionic and cationic surfactant systems.
Key functions include: viscosity building (achieving target 500–3000 mPa·s for consumer acceptance), suspension stability (preventing enzyme, fragrance, or abrasive particle settling), and clarity preservation in transparent gel detergents. In markets with hard water — particularly the Middle East and parts of Africa — JINJI HPMC demonstrates exceptional stability, maintaining consistent product performance where competing thickeners produce gel breakdown or phase separation.
The global HPMC market is projected to surpass USD 1.8 billion by 2030, driven by rapid urbanization, green building mandates, and the premiumization of home care products. Here are the key trends shaping demand for HPMC in wall putty, skim coat, and liquid detergent applications.
Rapid urban expansion across South Asia, Southeast Asia, and Sub-Saharan Africa is generating unprecedented demand for wall putty and skim coat products. Government-backed affordable housing programs in India, Indonesia, and Nigeria are driving large-scale consumption of HPMC-modified dry-mix mortars.
LEED, BREEAM, and regional green building certifications are pushing formulators toward bio-based, low-VOC additives. HPMC's natural cellulose origin and non-toxic profile position it as the preferred choice for sustainable wall finishing systems, replacing synthetic polymer alternatives.
Consumer demand for premium, high-viscosity liquid detergents with enhanced sensory properties is growing in emerging markets. HPMC enables manufacturers to formulate gel-format and concentrated detergents that command higher price points while reducing packaging and transportation costs.
The proliferation of high-rise residential and commercial towers in the Middle East, China, and Southeast Asia demands skim coat and wall putty systems with superior anti-sag, extended open time, and high-temperature stability — performance parameters that only premium HPMC grades can reliably deliver.
The shift from site-mixed to factory-produced dry-mix mortars is accelerating globally, driven by quality consistency requirements and labor cost pressures. Industrial dry-mix production demands HPMC grades with precisely controlled dissolution rates, particle size distribution, and viscosity profiles.
Regulatory pressure and consumer environmental awareness are driving the transition to concentrated, eco-certified liquid detergents. HPMC plays a critical role in maintaining the rheological properties of concentrated formulas while meeting biodegradability requirements of EU Ecolabel and similar certification schemes.
