Surfactants, with their amphiphilic molecular structure, are
crucial in cleaning and emulsification due to their ability to
adsorb at water and other media interfaces. In cleaning
products, they are key for effective dirt removal. Surfactants
work by lowering water’s surface tension, enhancing its
wetting ability on surfaces, and preventing dirt from
redepositing. They also modify the wetting properties of
solid contaminants and use charge repulsion to aid in dirt
removal.
