Trisodium ethylenediamine disuccinate

Trisodium ethylenediamine disuccinate (CAS 178949-82-1), commercially available as NATRLQUEST E30 and ENVIOMET C140, is a biodegradable chelating agent derived from aspartic acid.

It binds and sequesters metal ions such as calcium, magnesium, iron, and copper across a broad pH range, allowing formulators to replace conventional chelants like EDTA in sensitive applications.

In personal care and cosmetics, it stabilizes formulations by deactivating trace metals that would otherwise degrade active ingredients or cause discoloration. This ensures product longevity and safety.

Water treatment operations use it to control scale and metal deposition in process water systems where biodegradability is a regulatory or compliance requirement. It is an effective green alternative.

Textile and leather processing relies on it to sequester hardness ions during dyeing and finishing, improving color consistency and process efficiency. It prevents unwanted mineral interference.

In agriculture, it functions as a micronutrient carrier, keeping iron and other trace elements soluble and bioavailable in fertilizer formulations. This promotes healthy crop growth and yield.

Trisodium ethylenediamine disuccinate is typically supplied as an aqueous solution, with NATRLQUEST E30 indicating a 30% active concentration. Technical and industrial grades are the primary forms.

Certain solution grades meet criteria for use in cosmetic and agricultural applications. Packaging options generally range from drums to intermediate bulk containers depending on volume requirements.
