On April 23, 2026, new progress was made in the popularization and application of surfactant technology. As key functional materials with amphiphilic molecular structure, surfactants significantly reduce surface tension, delivering functions like wetting, emulsification, decontamination and sterilization, widely used in daily chemicals, industry and personal care. Surfactants are divided into four categories: anionic, cationic, amphoteric and non-ionic. Anionic surfactants such as sodium dodecylbenzene sulfonate excel in cleaning and foaming; cationic types feature sterilization; amphoteric surfactants offer mild performance; non-ionic surfactants boast stable emulsification and hard water resistance. HLB value serves as a core index for precise selection and formula compounding to meet diversified application scenarios. Driven by green and high-efficiency trends, surfactants keep upgrading with rising penetration in multiple sectors, providing solid technical support for industrial high-quality development.
