Key Applications
Salt- & Ion-Resistant Thickening
Maintains thickening performance in pharmaceutical formulations containing electrolytes or ionic actives, where a standard homopolymer grade would lose viscosity.
Frequently Asked Questions
Why choose AM-1382 over a homopolymer grade like AM-971P?
AM-1382 is a copolymer built specifically for salt- and ion-resistant thickening. If your formulation contains electrolytes, ionic actives, or higher-ionic-strength systems, AM-1382 maintains viscosity where a standard homopolymer would break down.
Is AM-1382 free of benzene and acrylamide?
Yes. AM-1382 is manufactured to be free of benzene and acrylamide, with benzene residue controlled to ≤2ppm.
Which pharmacopoeia standards does AM-1382 comply with?
Manufactured with quality control benchmarked against industry-standard reference grades, with batch documentation available to support your regulatory filings.
Do you provide certificates of analysis for each batch?
Yes, a batch-specific COA is provided with every shipment, along with ISO certification and MSDS/TDS on request. Regulatory documentation for pharmaceutical filings is available on request.
