Aminotris(methylenephosphonic acid) pentasodium salt

Aminotris(methylenephosphonic acid) pentasodium salt (CAS 2235-43-0) is the fully neutralised sodium salt form of ATMP, a phosphonate-based chelating agent. It is sold under trade names including Dequest 2006 and Kenrox 106, and carries no assigned E-code. It is registered under REACH and classified within the broader family of aminophosphonate sequestrants.

In cooling water and boiler systems, it inhibits scale formation by binding calcium, magnesium, and iron ions before they precipitate onto heat-transfer surfaces. In textile and paper processing, it sequesters hardness ions that would otherwise interfere with bleaching and dyeing chemistry, improving process consistency and reducing chemical consumption.

This product is supplied as an aqueous solution and is available in industrial drum and IBC formats suitable for B2B procurement. It falls under REACH registration requirements for European supply. Buyers should confirm concentration grade and ionic content with the supplier to match specific process tolerances.
