Application
1 Butylnaphtalenesulfonic Acid Sodium Salt is used as a wetting agent in the textile, printing and dyeing, leather and paper industries.
2 Butylnaphtalenesulfonic Acid Sodium Salt can be used as detergent, dyeing aid, dispersant, wetting agent, insecticide, herbicide and emulsifier in synthetic rubber industry.
3 As a penetrating agent and wetting agent, sodium 2-butyl-1-naphthalenesulfonate can be used in various processes in the textile printing and dyeing industry.
4. Butylnaphtalenesulfonic Acid Sodium Salt can be used as a wetting agent in the papermaking and color lake industries. Adding 10% penetrant BX solution to the organic pigment is beneficial to the modulation of color paste. It is used as an emulsifier in the preparation of rubber slurry.
Butylnaphtalenesulfonic Acid Sodium Salt Advantages
1. Active ingredient content > 60%.
2. Rapid spreading and penetration: It significantly reduces the surface tension of liquids, making it easier for them to spread across solid surfaces or penetrate into crevices. This significantly improves production efficiency and application effectiveness.
3. It helps immiscible oils and water form stable, uniform emulsions, preventing them from rapidly separating.

FAQ
Q: What is CAS 25638-17-9? What are its aliases?
A: Sodium butyl naphthalene sulfonate, commonly known as Penetrant BX, Pulling Powder BX (Nekal BX), belongs to the anionic surfactant of alkyl naphthalene sulfonate. It is a classic penetration and wetting aid in textile printing and dyeing, and can also be used as a dispersant and emulsifier.
Q: What are the core characteristics?
A: Excellent rapid penetration, wetting, re-wetting, emulsification, dispersion, foaming capabilities; adding a small amount of salt can further enhance the penetration power.
⚠️ Limitations: Cannot be used together with cationic surfactants or cationic dyes in the same bath, it will cause precipitation failure; In concentrated caustic soda solution, precipitation will occur, and it can be re-soluble after dilution; Cleaning force is generally average.
Q: Minimum Order Quantity (MOQ)?
A: Batch regular MOQ: 25kg. Packaging: 25kg woven bag / cardboard barrel; Customized label printing (customized labels have an additional MOQ).
