Hydroxyethyl Cellulose CAS Number: The Essential Identifier

The CAS Registry Number (9004-62-0) serves as the definitive chemical fingerprint for hydroxyethyl cellulose (HEC), distinguishing it from similar compounds like hydroxypropyl methyl cellulose (HPMC, CAS 9004-65-3). This alphanumeric code enables precise material identification across 14 regulatory jurisdictions, critical for:

• Global trade compliance (REACH, TSCA, GHS)
• Technical documentation standardization
• Safety data sheet (SDS) verification

Performance Benchmarking Across Polymer Grades

Third-party testing reveals significant performance variations between cellulose derivatives:

Parameter	HEC (9004-62-0)	HPMC (9004-65-3)	Testing Standard
Viscosity (2% aq.)	5,000-100,000 cP	4,000-150,000 cP	ASTM D2196
Gelation Temp	N/A	50-90°C	ISO 9665
DS Value	1.8-2.5	1.2-2.0	USP-NF

Manufacturer Capability Analysis

Top-tier producers demonstrate distinct specialization patterns:

• Ashland: 85% production capacity for pharmaceutical-grade HEC
• Dow Chemical: 72% market share in construction-grade HPMC
• Shin-Etsu: 50,000 MT/year cellulose ether output

Customization Protocols for Industrial Use

Advanced modification techniques enable precise parameter control:

1. Particle size distribution (10-200 μm)
2. Delayed hydration (0-120 min activation)
3. pH tolerance (3-11 stability window)

Documentation & Regulatory Compliance

Essential certifications for technical buyers:

• USP/NF monograph compliance
• ECHA REACH registration dossiers
• ISO 9001:2015 quality systems

Strategic Sourcing of Hydroxyethyl Cellulose Solutions

Procurement specialists should verify three critical parameters when sourcing hydroxyethyl cellulose CAS 9004-62-0:

1. Moisture content certification (<2.5% w/w)
2. Heavy metal screening (Pb <5 ppm)
3. Batch-to-batch viscosity consistency (±7%)
