Dissolvine D-40 is based on diethylenetriaminepentaacetic acid (DTPA) and its pentasodium salts, supplied as a versatile chelating agent used across multiple industries. Dissolvine D-40 serves as a stabilizer in peroxide and hydrosulfite bleaching for pulp production, as well as in bleaching and dyeing baths for textiles, helping formulators achieve efficient and consistent stabilization in demanding industrial processes.
What Is Dissolvine D-40?
Dissolvine D-40 belongs to the aminopolycarboxylic acid (APCA) and sodium salt chemical family. Its chemical name is pentasodium (carboxylatomethyl)iminobis(ethylenenitrilo)tetraacetate, carrying CAS number 140-01-2 and supplied as a liquid. It is also known under several synonyms, including diethylenetriaminepentaacetic acid pentasodium salt, DTPA pentasodium salt, pentasodium diethylenetriaminepentaacetate, and pentasodium pentetate.

Applications of Dissolvine D-40
Pulp Bleaching and Textile Processing
This chelating agent is widely applied as a stabilizer in peroxide bleaching and hydrosulphite bleaching baths during pulp production, where it helps protect bleaching efficiency from trace metal interference. In textile manufacturing, it performs a similar stabilizing role in bleaching and dyeing baths, supporting consistent color development and fabric quality.
Industrial and Home Care Applications
Beyond pulp and textile processing, Dissolvine D-40 supports applications across catalysis, electroplating, cement formulation, and photographic developer baths. Its chelating function also extends to home care and institutional cleaning formulations, including detergents, commercial laundry, and industrial cleaning products, where it helps control water hardness and metal ion interference.
Dissolvine D-40 is available on a global basis and is commonly specified by formulators working in HI&I care and broader industrial markets, including home care detergents, institutional and industrial cleaning, and chemical manufacturing. Because exact dosage, dilution and compatibility requirements vary by process and water chemistry, buyers should confirm formulation parameters against the current technical data sheet and safety data sheet before finalizing a formulation.
Sourcing Dissolvine D-40 for Industrial and Chemical Processing
Thousands Technology offers supply chain resource support for recommended international brand products such as this chelating agent, helping chemical traders, pulp and paper processors, textile manufacturers, and cleaning formulators secure consistent supply alongside the auxiliary agents and additives already sourced through our platform. Buyers documenting quality and process controls for bleaching or cleaning formulations can also reference general industrial chemical standards published by the ASTM D20 Committee on Plastics alongside their own process-specific specifications.
Formulators moving between suppliers for a DTPA pentasodium chelating agent should confirm active content, color, and pH specifications match their existing process, since minor compositional differences between suppliers can affect bleach stabilization performance in pulp and textile applications.
