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.
