It has high solubility in water, good wettability and permeability, and has strong emulsifying ability; The latter has a combined sulfuric acid content of more than 15%, can be dissolved in more than 10% concentrated solution, and is a completely transparent liquid that can show surface activity, which is a characteristic that many surfactants do not have.
