Description
Diethylenetriaminepenta(methylenephosphonic acid), commonly abbreviated as DTPMP and sold under the trade name Dequest 2060, is a phosphonate-based chelating agent with CAS number 15827-60-8. It carries no assigned E-code and is identified under EC number 239-931-4.
In water treatment, DTPMP inhibits scale formation and corrosion by binding calcium, magnesium, and heavy metal ions through its five phosphonate groups, preventing precipitation at low dosage levels. In textile and paper processing, it sequesters metal contaminants that would otherwise interfere with bleaching and dyeing chemistry, improving process consistency.
DTPMP is supplied as an oil-form liquid and is subject to REACH registration requirements for European market supply. Procurement teams should confirm supplier SDS documentation and confirm compliance with applicable industrial water treatment regulations in their jurisdiction. Packaging formats vary by supplier and order volume.
