Understanding Polyaspartic Acid Structure and Iminodisuccinate Derivatives
The polyaspartic acid structure is a repeating chain of aspartic acid units, forming a water-soluble, biodegradable polymer. Its unique helical configuration enables exceptional metal ion chelation and scale inhibition. Hebei Xiangdu’s polyaspartic acid derivatives are widely used in water treatment, agriculture, and detergents due to their non-toxic, eco-friendly properties.
Tetrasodium Iminodisuccinate (TSIDS) is a biodegradable alternative to phosphates and EDTA. With four sodium ions in its structure, it effectively binds calcium, magnesium, and heavy metals in industrial cleaning and textile processing. Verify that your supplier’s TSIDS meets ISO environmental management standards.
- Iminodisuccinic Acid: The base compound for derivatives like sodium and potassium salts, it offers strong chelation at neutral pH, ideal for agricultural micronutrient delivery.
- Iminodisuccinic Acid Sodium Salt: Used in detergents for its hardness tolerance and low aquatic toxicity.
- Iminodisuccinic Acid Potassium Salt: Enhances fertilizer efficiency by preventing nutrient leaching in soil.
Hebei Xiangdu holds 22 patents in China and international patents for these formulations, ensuring cutting-edge performance.
Critical Factors for Wholesalers When Sourcing Chelating Agents
Regulatory Compliance and Certifications

For wholesalers in agriculture, water treatment, or industrial chemicals, selecting reliable chelating agents such as calcium chelating agents, metal chelators, and copper chelators—is vital to ensuring product performance, regulatory compliance, and environmental sustainability. Hebei Xiangdu Chemical Co., Ltd., a subsidiary of the NEEQ-listed Hebei Xiangdu Environmental Co., Ltd. (Stock Code: ), has been a global leader since in producing biodegradable alternatives to traditional EDTA chelators.including patented Formula 6 Micronutrients. With 22 patents, a 15,000-ton annual production capacity, and exports to 30+ countries, this guide outlines essential strategies for wholesalers navigating this competitive market.
Understanding Chelating Agents and Their Applications
A calcium chelating agent binds calcium ions in hard water, preventing scale formation in boilers, cooling systems, and irrigation equipment. Hebei Xiangdu’s polyaspartic acid-based agents outperform phosphates by reducing scaling by 40–60% while being fully biodegradable (OECD 301B certified).
Metal chelators stabilize heavy metals like lead and cadmium in wastewater, enabling safe discharge or recycling. Unlike traditional EDTA chelators,Hebei Xiangdu’s iminodisuccinate-based formulas are non-toxic to aquatic life and comply with EU REACH and US EPA TSCA standards.
A copper chelator prevents copper ions from precipitating in fertilizers or etching solutions. For electronics manufacturers, Hebei Xiangdu’s chelators ensure pH stability (2.5–5.5) and low impurity levels (<1 ppm Fe/Ni).
Formula 6 Micronutrients is a patented blend of six essential trace elements (Fe, Zn, Mn, Cu, B, Mo) chelated with biodegradable polymers. This formulation increases nutrient uptake by 25–30% in alkaline soils, a common issue in regions like Australia and California.
While EDTA chelators remain popular, their persistence in ecosystems has driven demand for eco-friendly substitutes. Hebei Xiangdu’s calcium chelating agents and copper chelators match EDTA’s efficacy at 15–20% lower costs, with full biodegradability within 28 days.

Did you ever play with these as a child?
Those are stickle bricks or bristle blocks if you are from the USA.
They are also the closest thing in terms of free and easily relatable visual teaching aid that I can find to help communicate the power of the chelating agent.
If you are looking for a quick-fix definition and that’s all here it is. Chelating agents bind up trace metal ion contaminants in your water-containing cosmetic thus keeping the product microbe free for longer. They are not preservatives in their own right, they just help to kill microbes by starving them. They starve them by locking up or binding to their trace metal ion food supply.
In a cosmetic we use a small amount to boost preservative efficacy, especially in hard-to-preserve products.
But chelating agents are used in much higher volumes in other industries including water remediation, household cleaning, agrochemicals, textiles, chemical production, pharmaceutical manufacture, paint and coatings and soaping.
There are 141 Chelating agents registered in the European cosmetic ingredient database. Here are some of the most common ones:
EDTA – cheap, very effective and wide formula compatibility. Use at between 0.05-0.2% The down side is that this is made from petroleum derivatives and is therefore not a sustainable ‘green chemistry’ option. It also got a very bad wrap about ten years ago for its patchy biodegradability but since then the data gaps seem to have been filled and it now looks like as long as the soil is alkali EDTA biodegrades although some of the heavy metal complexes are more resistant to degradation and that is a worry. It is irritating to the eyes and skin in its neat form but then again most things are so that is less of a concern.
Sodium Phytate/ Phytic Acid – These are two of the new generation natural chelating agents. They are expensive though and are not as effective as EDTA BUT are natural and plant derived. Use between 0.1-0.3%
Citric Acid/ Sodium Citrate – This is a relatively poor chelating agent but it can help to boost preservative efficacy and bind some metal ions. Typically it is used at between 0.0-5-0.8% or to achieve a formula pH of between 4-5
Sodium Gluconate – This is a natural and gentle chelating agent which sounds lovely but I’m not sure you want your bug killers to be gentle. Anyway, it has a place and can help to boost preservation in natural formulations without sounding scary or overly ‘chemical. Use at 0.1-1% and best in acidic formulations.
NTA – This is what you get before you get EDTA so they are structurally similar. NTA is more commonly used as a chelator in industrial processes and cleaning products but rarely used in cosmetics.
EDDS (TRISODIUM ETHYLENEDIAMINE DISUCCINATE)– This is a structural isomer (same stuff but in a different order) of EDTA, an isomer that made it readily biodegradable. It is also made from sustainable resources so is a ‘green chemistry’ alternative to EDTA. EDDS came out of a company called Associated Octel whom I worked for when I was in the UK. We won a ‘Green Chemistry’ award for this and I spent many days talking to cleaning companies about how good it was vs EDTA so do check it out. Use between 0.05-0.2%
The next two have secondary chelating benefits that might be useful but shouldn’t necessarily be relied upon in difficult formulations.
Cyclodextrin – This works like a physical trap as cyclodextrins are structured a bit like Hoberman Spheres that trap metal ions inside them. Cyclodextrins are most often used in a formula to help protect and slow-release actives but this secondary chelating benefit is most welcome.
Activated Carbon (INCI: Charcoal) works like cyclodextrin too and can also help with chelation to a certain extent. Do see our post on Charcoal though to make sure you get the right stuff.
Here is a Hoberman Sphere, they make great toys!
Some natural extracts have chelating power too and there are a few listed on the European COSING database. Just be aware that while this is a great bonus, adding plant material to a formula makes it need a chelating agent more as plants come with trace metal ions. So in a way it is part of both the problem and the solution. As long as the benefits outweigh the risks I’d say that plant chelating is a great way to go.
I like to think of chelating agents as my tiny little soldiers that do an amazing job considering how little there is in the formula. I try to use chelating agents in all of my water containing formulations and recommend that you do too as a safe cosmetic is one that is microbially clean and protected.
