Surface active agent is a type of chemical with a special chemical structure that can reduce the surface tension of the liquid surface and make the liquid have good wetting and decentralization. Surface active agents are usually composed of hydrophilic groups and hydrophobic groups. The hydrophilic group likes water, while hydrophobic groups like oil or other non -polar solvents. This special structure enables the surfactant to play a role in interface activity between water and oil, reduce the surface tension of the liquid, and enable the two insoluble liquids to mix and form emulsion, colloid or stable dispersing systems.
Surface active agents are widely used in various fields, including cleaning agents, laundry liquids, shampoo, etc. in daily life, emulsifiers, dispersers, lubricants, etc. in industrial production, as well as agriculture, metallurgy, oil and other fields. The application of surfactants can improve the physical properties of liquid, increase its operability and effect, and improve the quality and use performance of the product.
