EDDS (Trisodium Ethylenediamine Disuccinate): The Ultimate Green Alternative to EDTA

In the global shift toward sustainable manufacturing, the demand for high-performance yet environmentally friendly chelating agents has reached an all-time high. Trisodium Ethylenediamine Disuccinate (EDDS) has emerged as the premier biodegradable alternative to traditional stabilizers like EDTA.

For industries ranging from personal care to industrial cleaning, EDDS offers the perfect balance between powerful chelation and ecological responsibility.

What is EDDS (Trisodium Ethylenediamine Disuccinate)?

EDDS is a structural isomer of EDTA, but with a critical difference: its molecular architecture allows it to be completely and rapidly biodegraded. It is a chiral molecule, and the [S,S]-isomer used in industrial applications is recognized globally for its excellent safety profile and minimal environmental footprint.

Why Switch to EDDS? Key Advantages

1. Exceptional Biodegradability

Unlike EDTA, which is persistent in the environment and can mobilize heavy metals in natural water systems, EDDS is "readily biodegradable" according to OECD 301B standards. This makes it the ideal choice for companies aiming for Green Seal or Ecolabel certifications.

2. High Selectivity for Transition Metals

EDDS exhibits a strong affinity for transition metal ions such as Copper (Cu²⁺), Iron (Fe³⁺), and Zinc (Zn²⁺). In many applications, particularly in hair care and pulp bleaching, EDDS outperforms other chelating agents by selectively targeting the ions that cause oxidation and product degradation.

3. Stability in Wide pH Ranges

EDDS maintains effective chelating power across a broad pH spectrum. This versatility allows it to be used in acidic facial cleansers as well as highly alkaline industrial degreasers.

Major Applications of EDDS

Personal Care & Cosmetics

In hair care products, EDDS is a "hero ingredient." It prevents the copper-induced formation of free radicals during oxidative coloring and UV exposure, significantly reducing hair fiber damage. In skin care, it enhances the efficacy of preservatives, allowing for milder formulations.

Detergents & Household Cleaning

EDDS improves the performance of laundry detergents by preventing soil redeposition and protecting colors. It is especially effective in heavy-duty liquid detergents where clarity and long-term stability are essential.

Industrial & Institutional (I&I) Cleaning

From vehicle washes to food processing plant sanitation, EDDS provides a sustainable way to handle hard water scale and metallic stains without compromising the facility's wastewater discharge quality.

Textile & Paper Industry

In hydrogen peroxide bleaching processes, EDDS stabilizes the peroxide by sequestering catalytic metal ions, ensuring a more uniform bleach and higher brightness of fibers.
