Iminodisuccinate Calcium (IDS-Ca) | Biodegradable Chelated Calcium for Agriculture & Industry

High-Performance Chelating Agent | Fully Biodegradable | Liquid & Solid Available | Customization Supported

Product Overview

Iminodisuccinate Calcium (IDS-Ca) is the calcium salt of iminodisuccinic acid (IDS)—a next-generation, environmentally friendly chelating agent. Its molecular structure features multiple carboxyl groups that form stable chelates with calcium ions, effectively preventing precipitation with phosphates, sulfates, and carbonates in soil and industrial systems. IDS-Ca offers superior performance to traditional chelating agents like EDTA and DTPA, with the added advantage of excellent biodegradability.

The product is available in both solid powder and liquid forms, delivering identical chelation performance across agricultural and industrial applications.

Developed and manufactured by Hebei Think Do Chemicals Co., Ltd, the product supports customization of packaging specifications, label design, formulation concentration, and OEM/ODM services. Full export documentation (COA, MSDS, TDS, commercial invoices, packing lists, etc.) is provided.

Key Benefits

Agriculture

Efficient Calcium Delivery: Prevents calcium fixation in soil; chelated Ca²⁺ remains available for plant uptake even in high-pH or phosphate-rich soils

Fertilizer Synergy: IDS-Ca can be co-applied with NPK fertilizers, reducing phosphate precipitation and improving overall nutrient use efficiency

Stress Resistance: Strengthens cell walls and membranes, reducing blossom-end rot (BER) in tomatoes/peppers and bitter pit in apples

Heavy Metal Passivation: IDS-Ca can effectively chelate Pb²⁺, Cd²⁺, Cu²⁺, and Zn²⁺ under neutral to slightly alkaline conditions, immobilizing them in contaminated soils

Inustry

Detergent & Cleaning Agent: Effective calcium sequestration in water treatment and industrial cleaning formulations

Scale Inhibition: Prevents calcium carbonate and calcium sulfate scale formation in cooling water systems, boilers, and pipelines

Metal Surface Treatment: Chelating agent for electroplating and metal finishing processes

Pulp & Paper: Calcium chelation to improve brightness and reduce scale formation

Application Guide

For foliar spray, dilute the product 800 to 1200 times with water. The solid form should be dissolved in warm water to prepare a stock solution first, then diluted to the final concentration. Apply during pre-flowering, fruit set, and fruit expansion stages for best results.

For drip irrigation, apply 1.0 to 2.0 kg per acre per application for the solid form, or 2.5 to 5.0 liters per acre per application for the liquid form. Repeat every 15 to 20 days during the active growing season.

For soil remediation, apply 3.0 to 8.0 kg per acre (solid) or 8.0 to 20.0 liters per acre (liquid). Incorporate into the topsoil or apply with irrigation water.

For industrial scale inhibition and chelation, a starting concentration of 50 to 200 ppm is recommended for both forms. Precise dosing should be determined by lab titration based on water hardness and specific system conditions.

⚠️ IDS-Ca is stable across pH 3 to 11. Avoid direct mixing with strongly alkaline products (pH > 11) or concentrated acids (pH < 3). For the solid form, always prepare a concentrated stock solution in warm water before final dilution.

Environmental Profile

IDS is readily biodegradable, achieving over 60% degradation within 28 days under OECD 301B test standards. This makes IDS-Ca an environmentally responsible choice compared to persistent chelators like EDTA. It offers comparable chelating capacity with a wider pH stability range and lower ecotoxicity. IDS-Ca is recognized under EU Ecolabel and Nordic Swan criteria for sustainable product formulations.

Packaging & Storage

The solid form is packaged in 25 kg composite bags with a polyethylene liner. The liquid form is supplied in 25 kg, 250 kg, or 1250 kg plastic drums, or in IBC containers. Custom packaging options are available upon request.

For storage, keep the solid product in a cool, dry, and well-ventilated area with bags tightly sealed. Store the liquid product at room temperature in sealed containers, protected from direct sunlight. The solid form has a shelf life of 24 months, while the liquid form is stable for 12 months under proper storage conditions.

⚠️ IDS-Ca is mildly irritating to skin and eyes. Wear gloves and goggles during handling. In case of contact, rinse thoroughly with water.

FAQ

Q: What is the difference between IDS-Ca and EDTA-Ca?

A: IDS-Ca offers comparable chelating capacity but is readily biodegradable vs. EDTA's environmental persistence, with a wider pH stability range (3-11) and lower ecotoxicity.

Q: How to choose between solid and liquid?

A: Solid offers lower shipping cost, longer shelf life (24 months), and flexibility for dry blending. Liquid is ready-to-use, saves dissolution labor, and is ideal for drip irrigation systems. Performance is identical.

Q: Can IDS-Ca be mixed with phosphorus fertilizers?

A: Yes. Chelated calcium does not precipitate with phosphates. Dissolve IDS-Ca in water first, then add phosphorus fertilizers.

Q: Is IDS-Ca suitable for organic farming?

A: IDS is biodegradable and approved under various green chemistry standards. Please verify with your local organic certification body for specific compliance.

Q: Can packaging be customized?

A: Yes. Hebei Think Do Chemicals Co., Ltd supports customized packaging, labeling, and OEM/ODM services. Contact us with your specific requirements.

Q: What is the shelf life?

A: Solid form: 24 months; Liquid form: 12 months under proper storage conditions.
