Product Name: Liquid Sodium Lignosulfonate (Liquid Sodium Lignosulphonate)
Product Code: GAC-NaLS-L
CAS Number: 8061-51-6
Appearance: Viscous, dark brown to black liquid
Source: Eco-friendly biopolymer derived from the wood sulfite pulping process
Liquid sodium lignosulfonate is a highly versatile, water-soluble anionic biopolymer. Unlike powder forms that require pre-mixing or dissolving, the liquid formulation is ready to use straight out of the tote. Green Agrochem specifically designs this grade to act as a potent industrial binder, plasticizer, and dust control agent. It is prized across heavy industries for its cost-effectiveness and excellent performance as a surface-active agent.
1. Chemical and Physical Properties
For industrial formulators, batch consistency is critical. Below are the standard guaranteed specifications for Green Agrochem’s Liquid Sodium Lignosulfonate (GAC-NaLS-L).
| Parameter | Standard Specification (GAC-NaLS-L) |
| Appearance | Black Liquid |
| Solid Content (Dry Matter) | 45.0%min |
| Lignosulfonate Content | 50.0%min |
| Water-Insoluble Matter | 1.5% |
| Sugar Content | 7.0% |
| Density | 1.20 – 1.30 g/ml |
Formulator’s Note: The 45% minimum solid content provides an excellent balance between high active-ingredient concentration and manageable fluid viscosity. Because it already possesses a density of 1.20–1.30 g/ml, it blends seamlessly into aqueous systems like concrete mixes and drilling muds without the clumping risks associated with powders.
2. Primary Applications and Use Cases
Green Agrochem highlights the sodium variant of liquid lignosulfonate as a primary choice for heavy construction and industrial binding, separating its use cases from agricultural-focused variants (like calcium or potassium).
- Concrete Admixtures (Water Reducer): It serves as an exceptional plasticizer and water-reducing agent. By wrapping around cement particles and repelling them from one another, it prevents clumping. This allows contractors to reduce water content by 10–15% while maintaining excellent flowability, ultimately resulting in stronger, denser concrete.
- Heavy-Duty Dust Suppression: When sprayed onto unpaved mining haul roads, construction sites, or rural gravel roads, the liquid penetrates the soil and binds dirt particles together. As it cures in the sun, it forms a tough, flexible, and water-resistant crust that slashes airborne dust by up to 90%.
- Animal Feed Pelleting: Used as a natural “glue” in the feed industry. Sprayed into the feed mix before heating and pressing, it improves the structural integrity of feed pellets, reducing dust (fines) and ensuring the pellets survive transit without crumbling.
- Coal-Water Slurry (CWS) Dispersant: In the energy sector, it disperses fine coal particles in water, keeping them suspended and preventing sedimentation. This lowers the viscosity of the slurry, allowing it to be pumped efficiently and burned as a liquid fuel.
- General Industrial Dispersant: Frequently utilized in the manufacturing of ceramics, textile dyes, pesticides, and carbon black to ensure uniform particle distribution and prevent agglomeration.
3. Packaging and Logistics
Because this is a bulk liquid product, handling and logistics look very different from powder distribution.
- Standard Packaging: Typically shipped in 1,000-liter IBC totes, 200-liter plastic drums, or massive bulk flexitanks for high-volume industrial consumers.
- Storage Conditions: Store in sealed containers in a cool, dry area away from extreme temperatures (ideally below 40°C). While it has excellent shelf stability, extended exposure to freezing temperatures or intense, direct heat could affect viscosity.
- Handling: Ready to use directly from the container. It can be easily pumped into concrete batching plants or water trucks for spraying.
4. Safety and Environmental Impact
One of the biggest selling points of Green Agrochem’s Liquid Sodium Lignosulfonate is its green profile. It transforms a renewable byproduct of the paper industry into a high-value industrial tool.
- Environmental Profile: 100% biodegradable and completely non-toxic. It is safe to use near sensitive ecosystems, crops, and water tables, making it an ideal, eco-friendly replacement for synthetic, petroleum-based binders and toxic chloride dust suppressants.
- Safety & Handling: Non-hazardous for transport. While it is safe to handle, standard PPE (gloves and goggles) is recommended to prevent temporary skin or eye irritation from splashes. It generally emits a mild, temporary pine-like odor upon application, which dissipates rapidly.
