Sodium dibutyl naphthalene sulfonate is an anionic surfactant supplied for industrial wetting, dispersing and emulsifying applications. Selecting a manufacturer should involve more than comparing a product name or quotation. Buyers should confirm the offered grade, typical properties, batch documentation, packaging and performance in the intended formulation.
Product Profile
The material is typically supplied as a light yellow to amber liquid with a mild characteristic odor. It is soluble in water and organic solvents and can be evaluated as a wetting agent, dispersant or emulsifier in compatible industrial systems.
| Parameter | Typical value |
|---|---|
| Appearance | Light yellow to amber liquid |
| Odor | Mild characteristic odor |
| pH (1% solution) | 7.0–9.0 |
| Density | 1.0–1.1 g/cm³ |
| Flash point | >100°C (closed cup) |
| Solubility | Soluble in water and organic solvents |
These are typical reference values rather than guaranteed limits. The batch Certificate of Analysis and agreed sales specification govern supplied material.
Applications to Discuss with the Supplier
- Textile processing: wetting and dispersion support in dyeing processes.
- Construction formulations: evaluation as a surfactant where improved wetting or workability is required in concrete or mortar systems.
- Agricultural formulations: surfactant use in compatible pesticide and related formulations.
- Oil and gas: evaluation in drilling-fluid and crude-oil dispersion systems.
- Industrial cleaning: wetting and emulsification support where the formulation has been compatibility-tested.
Performance depends on concentration, water quality, electrolyte level, other surfactants, temperature and process conditions. A laboratory trial should therefore be completed before commercial use.
How to Qualify a Sodium Dibutyl Naphthalene Sulfonate Manufacturer
Ask the supplier to identify the exact chemical and commercial grade rather than relying on a broad “naphthalene sulfonate” description. Sodium dibutyl naphthalene sulfonate should not be confused with sodium naphthalene sulfonate formaldehyde condensate, Dispersant NNO or other alkyl naphthalene sulfonates.
- Request the current TDS, SDS and a representative batch COA.
- Confirm which values are typical and which are contractual specification limits.
- Review appearance, pH, density, solubility and any application-specific performance test.
- Ask about batch traceability, retained samples and notification of manufacturing changes.
- Confirm minimum order, lead time, packaging, loading method and destination documents.
- Test a pre-shipment or qualification sample in the buyer’s actual formulation.
Packaging, Handling and Storage
Available supply options include drums and bulk containers, subject to order quantity and logistics confirmation. Store the product in a cool, dry place away from direct sunlight and keep containers tightly closed. Operators should follow the current SDS and use appropriate personal protective equipment, including gloves and eye protection. Packaging compatibility and local transport requirements should be confirmed before shipment.
