Any substance that dissolves in water and can significantly reduce the surface energy of water is called a surface active agent (surface active agent, SAA) or surface active substance. Surfactants reduce the surface tension of water by adsorbing at the gas-liquid two-phase interface, and can also reduce the oil-water interfacial tension by adsorbing between the liquid interfaces. Many surfactants can also aggregate in bulk solution as aggregates. Uses of Surfactant Surfactants have become a flexible and diverse class due to their physical and chemical effects such as wetting or anti-sticking, emulsification or demulsification, foaming or defoaming, solubilization, dispersion, washing, anti-corrosion, anti-static and corresponding practical applications. , A wide range of fine chemical products. In addition to being used as detergents in daily life, other applications of surfactants can cover almost all fine chemical fields.Surfactants are used as performance additives in many industry formulations, such as personal and home care, and countless industrial applications: metal processing, industrial cleaning, oil extraction, pesticides, etc. Cie-Chinamaterial supplier can provide amphoteric surfactants, anionic surfactants, cationic surfactants, nonionic surfactants, etc. Payment Term: Alipay, Western Union, T/T, Paypal, Credit Card etc. Shipment Term: By international express, by air, by courier, by sea, or as customers request.
