What is
Nonionic Surfactants
Non-ionic surfactants are a type of surfactant that does not ionize in water. They have the ability to reduce the surface tension of liquids and enhance wetting and spreading properties.
Unlike ionic surfactants, non-ionic surfactants do not carry a charge when dissolved or dispersed in water. Due to their compatibility with different materials and their mildness to the skin, they are widely used in various industries, including personal care products, detergents, agricultural chemicals, and pharmaceuticals.
We offer competitively priced non-ionic surfactant products & intermediates superior performance.
We are here to serve as your partner, delivering what you need, when you need it, and at the best price.
