Trisodium Ethylenediamine Disuccinate (EDDS): The Sustainable Powerhouse for Modern Chelation

In the evolving landscape of green chemistry, industrial manufacturers are rapidly transitioning from traditional chelating agents like EDTA and DTPA toward more sustainable alternatives. Trisodium Ethylenediamine Disuccinate, commonly known as EDDS, has emerged as the premier eco-friendly solution. Offering a unique balance of high performance and rapid biodegradability, EDDS is reshaping industries from personal care to heavy-duty industrial cleaning.

In this guide, we explore the physical properties, applications, and why Yuanlian Chemical is the trusted global supplier for high-purity EDDS.

1. What is Trisodium Ethylenediamine Disuccinate (EDDS)?

Trisodium Ethylenediamine Disuccinate is a biodegradable aminocarboxylate chelating agent. Unlike EDTA, which persists in the environment for decades, EDDS is a structural isomer of aspartic acid that microorganisms can easily break down.

Core Physical and Chemical Characteristics

• Chemical Formula: $C^{10}{H}^{13}{N}^{2}N{a}^3{O}^8$

• CAS No.: 178949-82-1

• Biodegradability: Classed as "Readily Biodegradable" according to OECD 301B standards.

• Chirality: The [S,S]-isomer of EDDS is the most commercially valuable due to its superior environmental profile.

• Stability: Maintains excellent stability across a wide pH range, specifically excelling in alkaline environments.

2. Key Physicochemical Advantages

Why is the industry shifting to EDDS? The answer lies in its specific chemical behavior:

1. Selective Chelation: EDDS shows a high affinity for heavy metal ions such as $C{u}^{2+}$, $F{e}^{3+}$, $Z{n}^{2+}$, and $M{n}^{2+}$. This selectivity is crucial in preventing oxidation and stabilizing formulas without over-chelating essential minerals in certain applications.

2. Environmental Compliance: Because it degrades into harmless natural components, EDDS helps manufacturers meet stringent "Green Label" certifications and environmental regulations worldwide.

3. Stability in Complex Systems: EDDS remains effective in the presence of oxidants (like hydrogen peroxide) and high-temperature processes, making it a robust alternative for textile and paper industries.

3. High-Impact Application Fields

Personal Care and Cosmetics

In shampoos, lotions, and soaps, EDDS serves as a preservative booster. By sequestering metal ions found in tap water, it prevents formula rancidity and improves foam stability, all while maintaining a "clean beauty" profile.

Industrial and Institutional (I&I) Cleaning

EDDS is a core component in biodegradable laundry detergents and dishwashing liquids. It effectively prevents lime-scale buildup and removes tough stains caused by mineral deposits, even in hard water conditions.

Textile and Pulp Industry

During the bleaching process, heavy metals can catalyze the decomposition of hydrogen peroxide, leading to fiber damage. EDDS stabilizes the bleaching bath, ensuring consistent brightness and material strength.

Agriculture and Soil Remediation

Due to its low toxicity and biodegradable nature, EDDS is used in specialized fertilizers and for the "washing" of heavy-metal-contaminated soils, allowing for safe remediation without leaving chemical residues.
