Market Overview
EDDS (Ethylenediamine Disuccinic Acid), as a high-performance biodegradable chelating agent, is accelerating the replacement of traditional EDTA (Ethylenediaminetetraacetic Acid) market. In the first half of 2026, global EDDS market demand showed explosive growth, especially in European and North American markets driven by stricter environmental regulations.
Replacing EDTA: An Irreversible Industry Trend
Environmental Pressure Drives Accelerated Substitution
Although EDTA is widely used as a traditional chelating agent, its biodegradability issues and heavy metal complexation residues are increasingly attracting attention:
- Environmental Persistence: EDTA degradation cycle in natural environment lasts for years, easily forming stable complexes with heavy metal ions, causing secondary water pollution
- Regulatory Restrictions: EU REACH regulations have listed EDTA as a Substance of Very High Concern (SVHC), with multiple European countries implementing strict restrictions on its use
- Ecological Toxicity: EDTA-heavy metal complexes have potential toxicity to aquatic organisms, affecting ecosystem balance
Core Advantages of EDDS
As an ideal EDTA substitute, EDDS has the following significant advantages:
- Excellent Biodegradability: EDDS degradation rate in natural environment can reach over 95% (OECD 301 standard test), with degradation cycle only 1/10 of EDTA
- Superior Chelating Performance: Chelating ability for calcium, magnesium, iron, copper and other metal ions is comparable to EDTA, with more stable performance under high temperature and alkaline conditions
- Environmentally Friendly: Degradation products are carbon dioxide and water, with no environmental residue and very low toxicity to aquatic organisms
- High Safety: Non-toxic, non-irritating, compliant with food contact materials and daily chemical product safety standards
Main Application Fields
1. Detergents and Cleaners
EDDS application in laundry powder, dishwashing agents, and industrial cleaners is growing rapidly. In 2026, global detergent industry demand for EDDS is expected to reach 120,000 tons, a year-on-year growth of 18%.
2. Agriculture and Fertilizers
EDDS application expansion in trace element fertilizers and pesticide formulations is rapid, meeting organic agriculture certification standards.
3. Pulp and Textile Industry
In pulp bleaching and textile pre-treatment processes, EDDS is replacing EDTA, reducing wastewater treatment difficulty.
4. Water Treatment
In industrial circulating cooling water and boiler water treatment fields, EDDS application is gradually expanding.
Biodegradability: Core Competitiveness of EDDS
Degradation Performance Data
According to OECD 301B test standard:
- 10-day degradation window: EDDS degradation rate reaches 98%
- 28-day complete degradation: Degradation rate reaches over 99%
- Half-life: 3-7 days in natural water bodies, 5-10 days in soil
In comparison, EDTA's 28-day degradation rate is less than 10%, with a half-life of several years.
Price Trends
As of June 2026, EDDS market prices show a steady upward trend:
- Domestic Market: Industrial-grade EDDS mainstream quotation range is ￥28,000-32,000/ton
- International Market: European FOB quotation is $4,200-4,800/MT
Compared to EDTA, EDDS prices are still about 40%-60% higher, but the price gap is gradually narrowing with scale production advancement.
Market Outlook
Overall, the EDDS market will continue its rapid growth trend in the second half of 2026:
- Demand Side: Rigid demand for EDTA substitution continues to be released
- Supply Side: Capacity steadily expands, but technical barriers are high
- Price Side: Expected to maintain slight upward trend
