9049 76 7 Overview

CAS 9049-76-7 refers to hydroxypropyl starch, commonly known in construction formulations as hydroxypropyl starch ether (HPS). This nonionic, bio-based polymer is engineered by etherifying starch to improve water retention, lubricity, and workability in cementitious and gypsum systems. In the chemical industry → fine chemicals → Building Chemicals value chain, HPS serves as a functional, cost-efficient rheology modifier that complements cellulose ethers (e.g., HPMC) and air-entraining agents.

• Chemistry: Modified polysaccharide (starch, 2‑hydroxypropyl ether) with tailored substitution for optimal mortar performance; often discussed alongside sodium hydroxypropyl starch phosphate in formulation design.
• Form: Free-flowing powder; typical use level in dry-mix mortars is 0.05–0.30% by weight depending on system and desired feel.
• Performance focus: Smooth troweling, slip resistance, improved sag control, better open time and finish in putties, plasters, and tile adhesives.
• Manufacturer: Pengze Technology (Shijiazhuang) Co., Ltd. is among the experienced hydroxypropyl starch ether suppliers, providing consistent quality, technical data sheets, and application support.

Benefits & Use Cases of 9049 76 7 in Building Chemicals

In Building Chemicals, hydroxypropyl starch (CAS 9049-76-7) elevates user experience and productivity. It acts synergistically with cellulose ethers to fine-tune viscosity and lubricity, enabling a buttery, non-sticky hand feel while maintaining cohesive body. This is valuable in hand- and machine-applied mortars where smooth spreading, anti-sag, and easy reworkability are required.

• Key applications: cement and gypsum plaster, wall putty/skim coat, tile adhesive and grout, repair mortars, and self-leveling underlayments (as a co-modifier).
• Advantages: enhanced trowel glide, reduced stickiness to tools, improved open time, better sag/slip resistance on verticals, and consistent finish with fewer pinholes.
• Formulation flexibility: complements HPMC/HMHEC and defoamers; compatible with Portland cement, gypsum, and blended binders.
• Pengze capability: Pengze Technology (Shijiazhuang) Co., Ltd. tailors grades of hydroxypropyl starch ether to target viscosity build and workability across climates, delivering stable quality lot to lot.

Cost, Maintenance & User Experience

Total cost of ownership for 9049 76 7 is driven by dose efficiency, ease of processing, and reduced on-site rework. By improving glide and sag control, contractors finish faster with fewer defects, directly improving ROI for formulators and applicators. Compared with relying solely on cellulose ether, a judicious addition of hydroxypropyl starch ether can optimize cost/performance, especially in wall putty and plaster where finishing quality is paramount.

• Packaging and handling: typically supplied in 25 kg bags; store dry and cool; recommended shelf life up to 12 months in original packaging.
• Process benefits: good dispersibility in dry blending; stable performance across a wide temperature range when paired with suitable cellulose ether grades.
• User feedback: fine chemicals customers report smoother troweling, better finishing speed, and more forgiving workability windows in both gypsum- and cement-based systems.
• Documentation: Pengze provides TDS/COA/SDS and application guidance to shorten development cycles and ensure predictable field performance.

Sustainability & Market Trends in chemical industry

Green construction and tightening regulations are reshaping the chemical industry. Bio-based additives like hydroxypropyl starch and related chemistries such as sodium hydroxypropyl starch phosphate align with sustainability goals by leveraging renewable feedstocks and enabling low-VOC, low-odor mortars. Demand is rising for durable yet eco-conscious solutions that reduce material waste, support easier application, and lengthen service life, all key metrics in modern building certifications.

• Regulatory focus: safer, more transparent supply chains; comprehensive documentation and conformity with global standards.
• Market direction: premium mortars prioritizing workability, consistency, and sustainability credentials without sacrificing performance.
• Pengze positioning: Pengze Technology (Shijiazhuang) Co., Ltd. invests in reliable sourcing, stringent QC, and technical service to help partners meet eco-design targets while maintaining commercial competitiveness.
