In daily chemicals, water treatment agents are used to manage water quality, improve product stability, and enhance performance. Here are some common types of water treatment agents used in daily chemicals and their functions:

• Ethylene Diamine Tetraacetic Acid (EDTA): Binds metal ions such as calcium and magnesium to prevent scale formation and improve product stability.

• Hydroxyethylidene Diphosphonic Acid (HEDP ): Used to stabilize metal ions and prevent scale and corrosion, enhancing the performance of cleaning products.

• Citric Acid: Often used as a chelating agent and pH adjuster, it helps in controlling metal ions and preventing scale.

• Phosphonates (e.g., ATMP, EDTMPS): Prevents the formation of scale and deposits by chelating metal ions, which is particularly useful in cleaning and industrial applications.

• Polycarboxylates: Help to prevent scale formation and improve the dispersal of dirt and grime.

• Sodium Metasilicate: Provides alkaline conditions that help prevent corrosion of surfaces and equipment.

• Benzotriazole: Used in some formulations to protect metal surfaces from corrosion.

• Citric Acid: Used to adjust the pH of products, ensuring optimal performance and stability.

• Sodium Hydroxide: Often used to increase the pH of formulations as needed.

• Polyacrylic Acids (e.g., PAA): Help to disperse particles and prevent the formation of clumps or deposits in formulations.

• Polyphosphates: Used to improve the dispersion of particles and prevent scale and sludge formation.

• Anionic Surfactants (e.g., Sodium Lauryl Sulfate): Used to create foam and improve cleaning efficiency.

• Nonionic Surfactants (e.g., Alcohol Ethoxylates): Provide mildness and stability in formulations.

• Household Cleaners: Chelating agents like EDTA and citric acid help in preventing scale and improving the effectiveness of cleaning agents.

• Laundry Detergents: Water softeners and anti-scaling agents such as phosphonates and polycarboxylates are used to enhance cleaning performance and prevent build-up in washing machines.

• Dishwashing Liquids: Chelating agents and anti-scaling agents are used to manage hard water and improve grease removal.

In summary, water treatment agents in daily chemicals are crucial for managing metal ions, preventing scale and corrosion, and enhancing the overall performance and stability of the products. The specific choice and concentration of these agents depend on the type of product and its intended application.
