Abstract
This paper examines the interactions of linear alkylbenzene sulfonate (LAS) surfactants with calcium ions. Calcium sulfonate precipitation boundary diagrams are given which provide a convenient way to study these interactions over a wide range of surfactant and hardness ion levels. Some implications of these interactions for detergency performance are discussed.
