PRODUCT INTRODUCTION
Our Humectant and Chelating Agent series is a group of multifunctional water-based chemical additives that play two essential roles in formulation systems. As humectants, they absorb and retain moisture, preventing drying, cracking and viscosity drift in coatings, inks, adhesives, ceramics and personal care products. As chelating agents, they bind and neutralize metal ions in water, eliminating the negative effects of calcium, magnesium and heavy metals on formulation stability and performance.
These two functions make the products extremely valuable in water-based systems where hard water or metal ion contamination is a common production problem. By controlling free ions, the chelating grade prevents precipitation, discoloration, rancidity, scale and emulsion breaking, while improving the efficiency of surfactants, thickeners and preservatives in the formula.
The humectant grade keeps the system moist during drying and curing, reducing skinning, edge drying, brush drag and poor flow, which are typical defects in fast-drying water-based paints and inks. It also supports better film formation and smoother surface quality without leaving greasy or sticky residues.
Both grades are supplied in liquid or powder form depending on application, with excellent water solubility, good pH tolerance and wide compatibility with resins, pigments, surfactants and other additives. They are easy to dose and blend into existing production lines without complicated process changes.
Typical downstream sectors include water-based paint and ink, emulsion polymerization, textile dyeing, leather processing, metal cleaning, agriculture, personal care and pharmaceutical formulations. Every batch is tested for chelating value, moisture retention, pH, appearance and storage stability before delivery, and complete COA, TDS and MSDS documents are provided for export and quality traceability.
POINTS FOR ATTENTION
ORDER INSTRUCTIONS
1. Confirm Grade and Function
Please tell us whether you need humectant, chelating or combined function, plus your application field, water hardness and formulation type. We will recommend the most suitable grade and reference dosage.
2. Confirm Form and Packaging
Available in liquid (25 kg / 200 L drums, IBC tanks) or powder (25 kg bags / cartons). Custom labels, pallet packing and shipping marks are available for export orders.
3. Delivery and Logistics
Please provide the delivery port or destination address. We will confirm lead time, loading plan and export documents before production.
4. Quality Assurance and After-sales Support
Each batch is supplied with COA, TDS and MSDS. If chelating performance, moisture retention or compatibility problems occur, our technical team will assist with re-testing and grade adjustment.
Trial Order Tip:
For new customers, we recommend a small trial batch first to verify chelating value, moisture retention and compatibility in your actual formulation before bulk order.

USAGE NOTES
Dosage Control:
Typical dosage is 0.1–1.5% for chelating grades and 0.5–3% for humectant grades. Start from the lower limit and increase gradually until the desired effect is achieved.

Adding Method:
Add during the water phase stage under moderate stirring, before adding resin or pigment slurry. Pre-dissolve powder grades in a small amount of water for better dispersion.

Water Hardness Check:
Test the hardness of your process water first. In high-hardness areas, increase the chelating dosage proportionally to fully neutralize calcium and magnesium ions.

Compatibility Pre-test:
Before mass production, verify compatibility with your resin, pigment, surfactant and thickener system. Observe pH, viscosity and storage stability changes.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Precipitation or Turbidity in Hard Water
Calcium and magnesium ions react with resins or surfactants, causing precipitation, turbidity and performance loss.
Solution: Add HC-100/200 chelating grade, increase dosage according to water hardness, and pre-treat process water if needed.
Skinning and Edge Drying in Paint
Fast water evaporation causes surface skinning, edge drying and poor leveling during application.
Solution: Add HC-300 humectant grade to retain moisture and extend open time; adjust drying conditions.
Viscosity Drift During Storage
Metal ions or moisture loss may cause viscosity instability and poor shelf life.
Solution: Stabilize the system with a chelating grade and control moisture with a humectant grade; verify pH range.
Poor Dye Uptake in Textile
Hard water ions block dye absorption and reduce color consistency.
Solution: Use HC-200 in the dyeing bath, adjust chelating dosage and check water hardness before production.
Scale and Corrosion in Industrial Fluids
Metal ions in circulating water cause scale formation and equipment corrosion.
Solution: Add chelating agent to boiler water or cutting fluid systems, and monitor ion concentration regularly.
Ink Nozzle Clogging in Printing
Moisture imbalance and metal ion residue cause drying and clogging in inkjet nozzles.
Solution: Use HC-300 humectant grade and HC-100 chelating grade together; filter and stabilize the ink system.
Emulsion Breaking in Polymerization
Metal ions destabilize polymer particles, causing coagulum and reaction failure.
Solution: Pre-treat water with HC-200 before polymerization; control raw material purity and reaction temperature.
Batch-to-Batch Performance Variation
Changes in water hardness, raw material quality or process conditions cause inconsistent results.
Solution: Standardize water quality, keep raw materials stable, and run a quick chelating/humectant test before each batch.
