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. It functions as a gelling, thickening, and stabilizing agent across food, pharmaceutical, and industrial manufacturing processes.

In food production, it controls texture and water retention in processed foods, dairy analogs, and structured meat products where precise gel strength is required. Pharmaceutical manufacturers use it as a binder and controlled-release matrix in tablet formulations.

It also serves as a wound dressing substrate that gels on contact with exudate. In textile processing, it serves as a print paste thickener for reactive dye application, delivering consistent viscosity across high-throughput printing operations.

Paper and board manufacturers apply it as a surface sizing agent to improve ink holdout and surface strength. This versatile compound is supplied as a cream to off-white powder for various industrial uses.

Food-grade and pharmaceutical-grade specifications are the primary commercial grades, with food-grade material typically produced to FCC standards. Technical-grade material is available for textile and industrial applications.

These industrial applications are suitable where tighter purity thresholds are not required. The material remains a critical component for manufacturers seeking reliable gelling and thickening properties in diverse chemical environments.
