Tetrasodium iminodisuccinate, also named IDS-Na4, is an eco-friendly phosphorus-free chelating agent, used to replace the traditional chelating agent HEDP, EDTA, DTPA, NTA, etc.

Tetrasodium iminodisuccinate is a powerful chelating agent used in various applications including cleaning and personal care products. It is also can be used as water treatment agent, scale inhibitor and water softener in traditional industrial circulation field.

1) Easily biodegradable, phosphorus-free, non-toxic and harmless to the ecosystem.

2) Excellent compatibility, high pH resistance and strong alkali resistance, and high temperature resistance. it can form stable complexes with metal ions, such as calcium, magnesium, iron, and copper, especially for copper under acidic conditions.

3) It has excellent stability to hydrogen peroxide H2O2. Under high alkaline conditions, the chelating stability constant of iron ion is still good, which can be used as stabilizer for hydrogen peroxide and oxygen bleaching.
