What is Trisodium ethylenediamine disuccinate?
Trisodium ethylenediamine disuccinate (CAS 178949-82-1) is a biodegradable chelating agent derived from aspartic acid. Also marketed as NATRLQUEST E30 and ENVIOMET C140.
Where is Trisodium ethylenediamine disuccinate used?
- Personal care and cosmetics: stabilizes formulations by deactivating trace metals that degrade actives or cause discoloration
- Water treatment: controls scale and metal deposition in process water systems where biodegradability is a compliance requirement
- Textile and leather processing: sequesters hardness ions during dyeing and finishing for color consistency
- Agriculture: micronutrient carrier keeping iron and trace elements soluble and bioavailable in fertilizers
- It binds and sequesters calcium, magnesium, iron, and copper across a broad pH range, replacing EDTA in sensitive applications.
Good to know: NATRLQUEST E30 indicates a 30% active concentration. Certain solution grades meet criteria for cosmetic and agricultural use.
Commercial specifications
- NATRLQUEST E30: 30% active
- Packaging: drums to intermediate bulk containers
