Shandong Yuanlian Chemical Co., Ltd. is a biodegradable chelating agent manufacturer serving formulators and distributors across Europe, North America, and Southeast Asia. We produce amino-acid-derived chelators that replace persistent EDTA and phosphate builders in detergents, water treatment, personal care, agriculture, and industrial cleaning. Our production base sits in Jiaxiang County, Shandong Province, with an annual capacity exceeding 12,000 tonnes of green chelating agents.

Buyers today face a clear shift. Regulators restrict phosphorus discharges, retailers audit restricted substance lists, and end users ask for products that break down after use. A reliable biodegradable chelating agent manufacturer helps you meet those demands without rebuilding your formulation from scratch.

Products from a Biodegradable Chelating Agent Manufacturer

We supply a complete portfolio of readily biodegradable chelators, each built on a natural amino acid backbone rather than petrochemical feedstock. This range lets formulators standardise on one supplier while moving away from persistent chemistry.

GLDA-Na4 (Tetrasodium Glutamate Diacetate)

GLDA-Na4 comes from glutamic acid. It shows strong calcium binding across a wide pH range and performs well in both alkaline and neutral systems. Formulators use it in detergents, industrial cleaners, and personal care products where hard-water control matters.

MGDA-Na3 (Trisodium Methylglycine Diacetate)

MGDA-Na3 is derived from glycine. It gives excellent magnesium chelation and supports phosphate-free automatic dishwashing and laundry formulations. Its stability at high pH makes it a practical EDTA replacement in heavy-duty cleaners.

PASP-Na (Sodium Polyaspartate)

PASP-Na is a biodegradable scale inhibitor and dispersant. It works in cooling water, boilers, and agricultural fertilisers, where it reduces scale formation and improves nutrient availability without adding phosphorus.

IDS-Na4 (Tetrasodium Iminodisuccinate)

IDS-Na4 comes from aspartic acid. It offers useful selectivity for iron and copper and stabilises hydrogen peroxide in bleaching and textile applications. Its chelation profile suits metal-sensitive processes.

ASDA-Na4 (Tetrasodium Aspartate Diacetate)

ASDA-Na4 is another aspartic-acid-based chelator with a balanced calcium and magnesium profile. It serves water treatment, cleaning, textile, and concrete retarding where a general-purpose biodegradable builder is needed.

EDTA and HEDP Derivative Series

For applications that still require traditional performance, we also supply EDTA series and HEDP series products. This lets formulators source both modern green chelators and established chemistries from one supplier.

Why Source from a Dedicated Biodegradable Chelating Agent Manufacturer

Choosing a specialist manufacturer gives you more than a material spec sheet. It gives you consistency, traceability, and technical backing.

We hold ISO 9001 certification and operate as a high-tech enterprise recognised under China's "Little Giant" programme for specialist innovation. Many buyers keep a single qualified supplier to simplify auditing and keep records consistent across product lines. Our team supports product selection, dosage guidance, and compatibility testing so your transition away from EDTA stays controlled.

Customisation is part of the service. We review your target active content, preferred packaging, and shipping cadence before confirming a specification. Whether you need 25 kg drums, 250 kg drums, or 1,250 kg IBC containers, we align supply with your volume.

Manufacturing Capacity of a Biodegradable Chelating Agent Manufacturer

Our plant runs continuous process control with in-house laboratories verifying each batch. Annual output across the green chelator range exceeds 12,000 tonnes, backed by dedicated synthesis lines for GLDA, MGDA, PASP, IDS, and ASDA. Key quality checks cover active content, pH, density, appearance, and heavy-metal limits. Batch records stay on file for traceability, and any abnormal result triggers a hold-and-review before release. We issue a Certificate of Analysis with every shipment and maintain Safety Data Sheets and Technical Data Sheets for each product.

Biodegradability is confirmed against recognised test methods such as OECD 301B, which measures ultimate aerobic biodegradation. For buyers responding to environmental procurement criteria, these data points support compliance documentation.

Global Supply of Biodegradable Chelating Agents

We export to more than 60 countries and work with distributors, compounders, and brand owners. Sea and rail freight options cover major ports, and our sales team coordinates documentation for REACH, CBAM, and local import requirements where applicable.

Technical support runs in parallel with logistics. Our application specialists answer questions on substitution ratios, formulation compatibility, and stability. We encourage pilot testing before full-scale changeover, and we supply free samples for that purpose.

Industries Using Biodegradable Chelating Agents

Our chelating agents reach several industries with different pain points:

• **Detergents and cleaning**: phosphate-free builders, hard-water control, peroxide stabilisation.
• **Water treatment**: scale and corrosion control without phosphorus discharge.
• **Personal care**: metal-ion control and shelf-life protection in clean-label products.
• **Textile and pulp**: dye-bath consistency, peroxide bleaching stabilisation.
• **Agriculture**: fertiliser additive for nutrient efficiency and anti-scaling.
• **Oilfield and construction**: scale inhibition and controlled concrete setting.

Each sector receives a tailored grade and dosage recommendation, because metal profiles and process conditions differ widely between plants.

Request Samples from a Biodegradable Chelating Agent Manufacturer

Starting a substitution project is straightforward. Tell us your current chelator, target application, and required volume. We return a recommendation, a quotation, and a free sample for bench testing.

**Contact our sales team at [email protected] or call +86-537-3739818 to request a sample and quotation.** Our technical staff can also join an initial call to review your formulation and suggest a transition plan.

Frequently Asked Questions

What is the minimum order quantity?

Standard MOQ starts at one pallet, but we discuss smaller trial quantities for qualified formulators running evaluation batches.

Do you provide REACH registration support?

We supply the documentation needed for import compliance and work with customers and their representatives on substance-related requirements.

How do I replace EDTA with GLDA or MGDA?

Replacement depends on your pH, target metal ions, and dosage. Our team reviews your formula and proposes a starting ratio, then you confirm through bench and field tests.

Are certificates available for every batch?

Yes. Each shipment includes a Certificate of Analysis, and TDS and SDS documents are available on request.

Can you match a specific active content?

We adjust active concentration to your specification during the customisation review, then confirm it through batch testing before shipment.
