Tetrasodium iminodisuccinate, abbreviated as IDS-Na4, is a phosphorus-free, degradable chelating agent.

1)Easy biodegradability, no phosphorus, friendly to the environment.
2)Excellent compatibility, strong alkali resistance, high temperature resistance.
3)Good chelating property to copper and iron ions.

Hard surface cleaning:
metal cutting, pipeline network cleaning, glass cleaning. Used with surfactants in cleaners, especially for rust and iron sulfide fouling, e.g. natural gas pipeline cleaning.
Water treatment chemicals: chelating agent to control water hardness and prevent scale.
Cleaning agents, detergents, soaping agents component.
Bleaching stabilizers for the paper pulp and dyeing industry.
Textile Auxiliaries: complexing agent, sequestering agent.
Electronic chemicals: Flat Panel Display FPD Chemicals.
Oilfield industry.
