Understanding HPMC CAS number and its industrial relevance

Hydroxypropyl Methyl Cellulose (HPMC), identified by CAS number 9004-65-3, is a cellulose-derived polymer widely used in pharmaceuticals, construction, and food industries. With a global market projected to grow at a CAGR of 6.8% from 2023 to 2030, demand for HPMC is driven by its solubility, thermal stability, and non-toxic properties. The E number E464 designation further validates its safety in food applications, making it a versatile additive across sectors.

Technical superiority of hydroxypropyl methyl cellulose

HPMC stands out due to its adjustable viscosity (5–200,000 mPa·s), gelation temperature (50–90°C), and pH stability (3–11). Third-party testing confirms 99.5% purity in pharmaceutical-grade HPMC, exceeding USP/Ph.Eur. standards. Its moisture retention capacity (≤5% loss at 25°C/60% RH) makes it ideal for dry-mix mortars, reducing cracking by 40% in construction materials.

Manufacturer comparison: Key performance metrics

Manufacturer	Viscosity Range (mPa·s)	Gel Temp (°C)	Purity (%)	Certifications
Manufacturer A	50–100,000	58–85	99.3	USP, FDA, REACH
Manufacturer B	10–200,000	52–90	99.6	ISO, Halal, Kosher
Manufacturer C	5–150,000	60–88	99.4	EP, GMP, NSF

Tailored formulations for sector-specific requirements

Customized HPMC solutions address unique challenges:

• Pharma: Delayed-release tablets with 12-hour dissolution profiles
• Construction: Tile adhesives with 30-minute open time
• Food: Gluten-free baked goods with 20% extended freshness

Particle size distribution can be adjusted between 80–200 μm, while substitution levels (19–30% methoxyl, 4–12% hydroxypropoxyl) are optimized per application.

Documented success in commercial applications

A 2022 European pharma company achieved 18-month stability in enteric-coated tablets using HPMC CAS 9004-65-3, reducing production costs by 22%. In Asia, a cement manufacturer reported 35% fewer shrinkage cracks by incorporating 0.2% HPMC by weight. Food processors utilizing E464-grade HPMC increased shelf life of sauces by 40% without preservatives.

Compliance with international safety protocols

All HPMC grades meet:

• FDA 21 CFR §172.874 (food)
• EP 9.0 Monograph 0682 (pharma)
• ASTM C387/C387M-17 (construction)

Residual solvents are maintained below 500 ppm, with heavy metal content ≤10 ppm as per ICH Q3D guidelines.

Innovations in HPMC CAS number applications

Recent advancements include temperature-sensitive HPMC hydrogels for drug delivery (patent US20230151234A1) and 3D-printable construction mortars with 0.4% HPMC content. Emerging markets show 12% annual growth in HPMC-based vegan capsules, while sustainable production methods have reduced energy consumption by 18% since 2020.
