Corrosion and scale inhibitors, used for corrosion prevention and scale control in cooling water circulation systems; the dataset includes primary raw materials, auxiliary materials, energy inputs, and waste generated during production, but does not include infrastructure such as production equipment and facility construction within its system boundaries; the life cycle inventory is compiled from data sourced from multiple references; the manufacturing process of corrosion and scale inhibitors involves mixing, formulation, and packaging of organic acids, additives, and solvents.
