Overview of Anionic Polyacrylamide Concrete Polymer Powder
Anionic surfactants are a class of surface-active agents characterized by a negatively charged hydrophilic head group when dissolved in water. This charge arises from the presence of a sulfate, sulfonate, phosphate, or carboxylate group. They are among the most widely used surfactants due to their effective cleaning properties, foaming capacity, and broad compatibility with other formulation ingredients. Anionic surfactants find extensive application across industries, including personal care, household cleaning, textiles, and industrial processes.
