Liquid Lignosulfonate Grades: Sodium, Calcium and Potassium Comparison

·

·

Liquid lignosulfonate is supplied as sodium, calcium and potassium salt grades for direct dosing, blending and bulk industrial use. The grades are not interchangeable: salt form, solids, insoluble matter, lignosulphonate content, reducing sugars, pH and density all affect handling and application performance. Select a grade by product code and confirm shipment values from the batch COA.

Liquid Grade Comparison

The values below are typical values from the current Green Agrochem technical data sheets (Revision 2.0 for each grade). They are reference values, not a binding specification; the COA accompanying each shipment reports batch results.

Parameter Liquid Sodium – Grade One Liquid Calcium Liquid Potassium
Product code GAC-NaLS-L GAC-CaLS-L GAC-KLS-L
Appearance Black liquid Black liquid Black liquid
Solid content 45% min 45% min 45% min
Water-insoluble matter 1% max 2% max 2.5% max
Lignosulphonate content 50% min 45% min 45% min
Reducing sugar Around 7% Around 4% Around 4%
Density 1.20–1.32 g/ml 1.265 g/ml 1.20–1.30 g/ml
pH 7.0–11.0 Around 5.0 4.0–7.0
Other – – K2O 8–10%

Solid content and lignosulphonate content are different measurements and may be reported on different bases. When comparing offers or converting a dosage, confirm whether a percentage refers to the liquid as supplied or to dry solids.

Where Each Grade Is Evaluated

Application suitability and addition level must be established by laboratory and plant trials with the actual materials and process. For concrete trials, see liquid lignosulfonate for concrete workability.

Packaging, Handling and Storage

Supplied in IBC totes or flexitanks. Store in a cool, dry, well-ventilated area and protect from freezing. Shelf life is 12 months from the date of manufacture under recommended storage conditions. Avoid mist inhalation and eye or skin contact, keep containers closed when not in use and follow the current SDS.
