Super sodium lignosulfonate (GAC-NaLS-Super) is the highest-purity sodium lignosulfonate in the LigninCorp range: 95% min lignosulphonate on a dry basis, completely water-soluble, supplied as a brown powder for dispersant and emulsifier use.
Standard sodium lignosulfonates contain roughly 50–70% lignosulphonate; the rest is mainly wood sugars and inorganic salts. The super grade removes most of that, so each kilogram carries more working dispersant and fewer by-products that can upset a sensitive formulation.
The TDS lists three uses: a dispersant for agrochemical, dye and pigment formulations, an emulsifier for oil-water systems, and other formulations that need very high lignosulphonate purity. For how it is used in pesticide formulations, see super sodium lignosulfonate for pesticide formulations.
Super Sodium Lignosulfonate Specification
| Parameter | Typical value (TDS GAC-NaLS-Super, Rev. 2.0) |
|---|---|
| Appearance | Brown powder |
| Lignosulphonate content | 95% min (dry basis) |
| Dry matter | 95% min |
| Water-insoluble matter | 0.5% max |
| Calcium & magnesium | 0.5% max |
| Moisture | 5% max |
| TDS / MSDS | TDS · MSDS |
Values are typical results for reference; the COA shipped with each lot states the measured batch values. The TDS gives no pH, reducing-sugar or sulphate limit: where these matter for your process, ask for them to be reported on the COA. For what each value means, see the super sodium lignosulfonate technical reference on Lignosulfonate.com.
Choosing Between High-Purity Sodium Grades
“High purity” can mean more lignosulphonate, fewer insolubles, or extra limits for food use. The table puts the current TDS values side by side.
| Grade | Lignosulphonate | Water-insoluble | Ca & Mg | Extra limits | Main use on the TDS | Documents |
|---|---|---|---|---|---|---|
| Super grade (this page) | 95% min (dry basis) | 0.5% max | 0.5% max | — | Dispersant and emulsifier in agrochemical, dye and pigment formulations | TDS · MSDS |
| Food grade (GAC-NaLS-Food) | 90–95% min | — | — | Reducing sugars 2% max, sodium sulfate 3% max, heavy-metal limits | Food processing | TDS · MSDS |
| Dispersant grade | 70% min (dry basis) | 0.5% max | 0.5% max | — | Agrochemicals, concrete, ceramics, dyes | TDS · MSDS |
| Emulsifier grade | 70% min (dry basis) | 0.5% max | 0.5% max | — | Oil-in-water emulsions and suspensions | TDS · MSDS |
| Plus grade | 65% min (dry basis) | 1% max | 0.5% max | Reducing sugar 7% max | Concrete, binders, general dispersing | TDS · MSDS |

Buyer Questions
What is the CAS number of super sodium lignosulfonate?
The GAC-NaLS-Super MSDS lists CAS 8061-51-6, the number for the sodium salt of lignosulfonic acid.
How is the super grade different from the dispersant grade?
Both have 0.5% max water-insoluble matter and 0.5% max calcium and magnesium. The super grade has 95% min lignosulphonate (dry basis); the dispersant grade has 70% min. Choose the super grade when the recipe needs the most dispersing power per kilogram, and the dispersant grade when cost per kilogram matters more.
Is the super grade a food-grade product?
No. The super grade TDS sets no limits for heavy metals or reducing sugars. Food-grade sodium lignosulfonate (GAC-NaLS-Food) is a separate product with those limits.
What documents come with an order?
The current TDS and MSDS are available before you order, and every lot ships with its own Certificate of Analysis (COA) giving the measured batch results.
How is it packed and how long does it keep?
25 kg woven bags with liner, or 500 kg or 600 kg jumbo bags (FIBC); other packing on request. Shelf life is 24 months from production in the original unopened packaging, stored cool and dry.
