A magnesium lignosulfonate technical data sheet is useful only when its product code, revision, test basis and supplier status match the material being offered. LigninCorp’s public archive contains an older GAC-MgLS PDF created in November 2016. It is retained for document traceability, but it must not be treated as the current specification for a new order.
For a current commercial route, review the Magnesium Lignosulfonate product page and request the applicable controlled TDS, SDS and representative COA before qualification.
Document Status at a Glance
| Document/data layer | Status | Correct use |
|---|---|---|
| Archived GAC-MgLS PDF | Created November 2016; no current revision or approval status is shown. | Historical reference only. Do not use for a new purchase specification or production dosage. |
| Current exact-grade TDS | Must be requested and matched to the quoted product code. | Use for agreed specification limits after checking revision, units, basis and methods. |
| Exact-grade SDS | Must match the supplied grade and destination-market requirements. | Use for handling, storage, transport and workplace review; it is not a performance specification. |
| Representative COA | Batch-specific. | Use to evaluate production consistency and compare with agreed acceptance limits. |
| Application recommendation | Valid only when the exact grade, revision, application and calculation basis are stated. | Use as a starting trial condition, followed by laboratory and plant validation. |
Archived 2016 Values—Not Current Specifications
| Parameter | Value shown in archived PDF | Evidence/status | Required action |
|---|---|---|---|
| Product code | GAC-MgLS | Historical identifier. | Confirm that the current quotation uses the same controlled grade identity. |
| Appearance | Yellow-brown powder | Historical document description. | Confirm the current exact-grade description and acceptance language. |
| pH | 4–7 | Historical value; solution concentration and method were not stated. | Obtain a current limit with sample preparation and method. |
| Dry matter | ≥95% | Historical value; method not stated. | Confirm whether the current document reports dry matter or moisture and the test basis. |
| Water-insoluble matter | ≤1.0% | Historical value; method not stated. | Confirm dissolution, filtration and drying method. |
| Total magnesium and calcium | ≥8% | Historical combined result; not the same as magnesium alone. | Request current individual/combined definitions and analytical method. |
| Lignosulfonate | ≥55% | Historical value; analytical definition not stated. | Confirm the current method and whether the result is on an as-supplied or dry basis. |
| Sulfate | ≥2% | Direction appears unusual for an impurity/control parameter and lacks a method. | Quarantine pending technical review; do not copy into a new specification. |
| Total reducing matter | ≥7% | Direction appears unusual and lacks a method. | Quarantine pending exact-grade document review. |
| Bulk density | 0.55 g/cm³ | Historical single value; packing/measurement method not stated. | Treat only as unverified historical information until a current typical value and method are supplied. |
| Moisture | ≤7% | Historical value; potentially inconsistent with separately listed dry matter depending on methods. | Reconcile both parameters in the current controlled TDS. |
These figures are reproduced for traceability under the site’s data-preservation rule. They are not current LigninCorp specifications, and they should not be copied into a purchase order, customer TDS or COA acceptance table without a current approved source.
Reviewing a Current TDS
- Match the product code on the quotation, sample label, TDS, SDS and COA.
- Record the document title, revision/date and issuing entity.
- Separate specification limits from typical properties and application results.
- Check units, sample preparation, dry/as-supplied basis and test methods.
- Resolve apparent conflicts such as dry matter versus moisture or magnesium versus combined magnesium-and-calcium.
- Agree which parameters are release tests and which are informational only.
- Compare representative batches before approving routine supply.
Dosage and Performance Data
The archived PDF listed 0.2–0.3% based on cement. It did not define whether the percentage was as-supplied product or dry solids, identify the cement system or test method, or provide a current document revision. The value therefore remains an unverified historical dosage statement and is not presented as a current recommendation.
A valid supplier-recommended starting trial range must name the exact grade and current source document, define the basis (normally including total cementitious material and as-supplied versus dry solids), and be tested with the actual cement, SCMs, aggregates, water, temperature, mixing and other admixtures. Water reduction, setting, air, slump retention and strength are measured results—not guaranteed consequences of dosage.
Application Qualification
Depending on exact grade and testing, magnesium lignosulfonate may be screened in concrete/cement, ceramics and refractories, mineral or powder binding, dust control and selected aqueous dispersion systems. Do not infer universal suitability from the application list. Define the control, preparation method, trial matrix, acceptance endpoints and scale-up conditions for each system.
Feed uses belong to the Animal Nutrition division and require feed-grade and jurisdiction-specific review. Pesticide-formulation dispersants belong to the Surface & Interface Technology division. This page does not establish regulatory suitability for either use.
