This webpage is not a Safety Data Sheet. It is a buyer and workplace review guide for Magnesium Lignosulfonate — Grade One, GAC-MgLS-1. Obtain the supplier-issued current SDS for the exact product code and destination market before handling, transport or use.
OSHA’s Safety Data Sheet Appendix D specifies the information required under the standardized headings. SDS responsibilities and jurisdictional requirements depend on the product, market and responsible manufacturer/importer.
Current document identity and review status
| Field | Reviewed document | Buyer action |
|---|---|---|
| Product | Magnesium Lignosulfonate — Grade One | Match the label, order, lot COA and SDS to the same product |
| Product code | GAC-MgLS-1 | Do not use for GAC-MgLS-2, liquid or feed grades |
| CAS | 8061-54-9 | CAS identity does not replace the commercial-grade identity |
| Document | GAC-MgLS-1-MSDS, Rev. 1.0 | Request the current signed/controlled issue applicable to the destination |
| Preparation/revision date | Not shown in the reviewed document | Technical-document owner should add the issue/revision date before relying on the document for regulated supply |
| Responsible-party contacts | Supplier name, website and email shown; complete address, telephone and emergency number not shown in the reviewed summary | Confirm and add all destination-required Section 1 contact fields |
Hazard classification reported by the current SDS
GAC-MgLS-1-MSDS Rev. 1.0 reports the powder as not classified as hazardous under normal industrial handling based on available data and assigns no signal word. This is the supplier document’s classification statement for the identified grade; it is not an absolute claim that all magnesium lignosulfonates are “non-toxic,” risk-free or non-combustible in every condition.
The document identifies fine powder as a possible source of temporary mechanical irritation to eyes, skin, nose or throat. Workplace controls must reflect the actual dust generated by unloading, transfer, mixing, cleaning and spill response.
Handling, exposure control and storage summary
- Use adequate general or local exhaust ventilation where dust may be generated.
- Avoid generating or breathing dust; use suitable particulate respiratory protection when airborne dust is present and according to the employer’s respiratory-protection programme.
- Use safety glasses and protective gloves during handling and maintain appropriate work clothing and hygiene.
- Store in a cool, dry, well-ventilated area away from heat, moisture ingress and incompatible strong oxidizing agents, strong acids and strong bases.
- Keep packaging closed and protected from damage; manage spilled powder to prevent dust clouds, slips and release to drains or waterways.
First-aid information reported in Rev. 1.0
| Exposure route | Document-reported response |
|---|---|
| Inhalation | Move to fresh air; seek medical attention if irritation or breathing discomfort persists |
| Skin | Flush with water and wash with soap/water; obtain medical advice if irritation persists |
| Eyes | Flush immediately with clean water for at least 10 minutes; obtain medical attention if irritation persists |
| Ingestion | Rinse mouth; seek medical attention if discomfort occurs |
Use the current controlled SDS and local emergency procedure in an actual incident. The webpage must not be the sole emergency reference.
Fire, reactivity and spill summary
The reviewed SDS lists water spray, foam, dry chemical or carbon dioxide as suitable extinguishing media selected for the surrounding fire. It states that combustion may generate carbon oxides, sulfur oxides and irritating fumes and recommends self-contained breathing apparatus in enclosed areas. The material should be kept away from excessive heat, strong oxidizers, strong acids and strong bases.
For spills, avoid dust generation, wear suitable protective equipment, collect material into an appropriate container and prevent large releases to drains, waterways or soil. Disposal and residual wash-water handling must follow the applicable site and local requirements.
Physical-property data in the reviewed grade document
| Property | GAC-MgLS-1 document value | Interpretation |
|---|---|---|
| Appearance | Yellow-brown powder | Physical identity |
| pH | 4–7 | Confirm preparation concentration and method |
| Dry matter | 95% min | Grade property; not a hazard classification |
| Water-insoluble matter | 1.0% max | Grade property |
| Total magnesium and calcium | 8% min | Confirm analytical basis |
| Lignosulphonate content | 55% min | Grade property |
| Sulphate | 2% min | Grade property |
| Total reducing matter | 7% min | Confirm definition and method |
| Density | 0.55 g/cm³ | Confirm bulk-density method before engineering use |
| Moisture | 5% max | Grade property |
These composition/physical fields do not prove safety, toxicity or performance. Use the current TDS and lot COA for product acceptance and the SDS for hazard communication.
Environmental, transport and regulatory limitations
The current SDS states that product-specific aquatic-toxicity data are unavailable and that destination-country regulatory requirements must be verified. Accordingly, this page does not claim zero ecotoxicity, complete biodegradation, no bioaccumulation or universal transport exemption. The SDS reports the grade as not regulated as dangerous goods based on available information, but the shipper/importer must confirm the current product, package, route and applicable transport rules.
Do not discharge large quantities to drains or natural waterways. Waste, contaminated material and packaging require site- and jurisdiction-specific classification and disposal.
Evidence status of former absolute statements
| Former statement | Evidence/status | Correct treatment |
|---|---|---|
| “Bio-based, non-toxic and non-flammable powder” | Overbroad; hazard classification is conditional and fire decomposition products are identified | Use the exact SDS wording and workplace risk assessment |
| Ingestion has low toxicity and only massive quantities cause mild discomfort | No defined acute oral dataset or dose identified on the former page | Do not publish a toxicity conclusion; follow SDS first aid and obtain medical advice as needed |
| No chronic effects; not carcinogenic or mutagenic | Absence of a listed classification is not proof of complete chronic/mutagenicity testing | State available-data limits and use current regulatory/toxicological review |
| Active lignosulfonate ≥50%, Mg about 6%, sugar 2–7%, moisture ≤5% and pH 4–7 as one generic MSDS composition | Composite values not tied to the exact current Grade One document | Use the GAC-MgLS-1 values above or the exact alternative-grade documents |
Obtain the correct document package
Request the current controlled SDS/MSDS, TDS and signed shipment COA for the exact code and lot. Confirm preparation/revision date, responsible-party address/telephone/emergency contact, regional language and regulatory applicability before approval.
