  • Surfactant formulations are used to remove fats in washing processes, complexing agents and dispersants are added to the treatment bath to remove unwanted hardness agents and heavy metals. If complexes of complexing agents are already acid-buffered formulations, their effect can be optimized by an improved acid solubility of alkaline earth or heavy metal salts.
