Ammonium calcium alginate

Ammonium calcium alginate (CAS 9005-31-6), commercially known as Keltose, is a mixed salt of alginic acid combining ammonium and calcium cations.

Where is Ammonium calcium alginate used?

• Food: controls texture and water retention in processed foods, dairy analogs and structured meat products
• Pharmaceutical: binder and controlled-release matrix in tablet formulations
• Wound care: dressing substrate that gels on contact with exudate
• Textile: print paste thickener for reactive dye application
• Paper and board: surface sizing agent improving ink holdout and surface strength
• It functions as a gelling, thickening and stabilizing agent in manufacturing processes.

Good to know: Food-grade material is typically produced to FCC standards; technical-grade material is for textile and industrial applications where tighter purity thresholds are not required.
