For industrial handling, our safety data sheet states that sodium lignosulfonate is not expected to be hazardous to skin under normal use. It may cause mild irritation, especially as fine powder or with prolonged contact, so gloves are still recommended. This article covers what the SDS says, and what it does not.
What the SDS says about skin
| SDS section | Statement |
|---|---|
| 2. Hazards | Fine powder may cause temporary mechanical irritation to eyes, skin, nose or throat |
| 4. First aid, skin contact | Not expected to be hazardous to skin under normal use. Remove contaminated clothing; flush with water, then wash with soap and water; seek medical advice if irritation persists |
| 8. Skin protection | Protective gloves and suitable work clothing recommended |
| 11. Toxicology | May cause mild irritation to eyes and skin; no specific acute toxicity effects documented in available data |
Practical advice
- Wear gloves when handling powder or liquid for long periods.
- Wash skin with soap and water after contact; damp powder can feel sticky but washes off with water.
- People with sensitive skin or existing skin conditions should avoid repeated bare-hand contact.
- Eyes are more sensitive than skin: rinse for at least 10 minutes if powder gets in them.
What this does not cover
This information is for industrial handling. Our industrial and agricultural grades are not sold for cosmetic or personal-care use, and their SDS is not a cosmetic safety assessment. Any use in products applied to skin needs its own safety assessment under the rules of the market concerned.
