Industria de tratamiento de agua

• 2-Hydroxyphosphonoacetic acid (HPAA) is widely used in industrial water treatment as a low-phosphorus scale and corrosion inhibitor capable of operating under alkaline, high-hardness and high-temperature conditions. Its molecular structure contains phosphono, carboxyl and hydroxyl groups, giving it strong chelating strength toward Ca²⁺, Mg²⁺, Fe³⁺ and other metal ions while maintaining excellent calcium tolerance. In circulating cooling-water systems used in power plants, petrochemical plants and large industrial facilities, HPAA interferes with CaCO₃ and CaSO₄ crystal nucleation and growth, producing fine, non-adherent crystals that prevent deposition on heat-exchange surfaces.
• Another key advantage of HPAA is its ability to provide both scale and corrosion inhibition in a single component. By adsorbing onto metal surfaces, HPAA forms a compact protective layer that limits oxygen and chloride attack on carbon steel and alloy pipelines. HPAA also demonstrates strong resistance to oxidative biocides such as chlorine, making it stable in cooling systems where oxidizing disinfectants are continuously dosed. In high-alkalinity cooling-water programs (pH 7–10), HPAA is often blended with acrylic polymers and zinc salts to enhance its performance in high-cycle, high-conductivity environments.
• HPAA is also used in boiler water systems to prevent internal scaling within steam drums and heat-transfer tubes. Its chelating action keeps hardness ions soluble under elevated temperatures, reducing the formation of carbonate and phosphate scales. In oilfield injection water, HPAA effectively controls barium, strontium and calcium scales in high-salinity, high-temperature pipelines and injection wells. Because oilfield injection systems often contain high concentrations of dissolved salts, HPAA’s strong tolerance to salinity and temperature makes it suitable for long-term continuous injection. In reverse-osmosis (RO) desalination systems, HPAA is applied as a low-phosphorus membrane antiscalant to suppress carbonate and sulfate scaling on membrane surfaces while supporting long cleaning cycles and stable permeate flow.

Industria de pulpa y papel

• HPAA is used throughout pulping, bleaching and papermaking because of its metal-chelating and stabilizing properties. In pulping processes, HPAA binds iron, copper and manganese ions that otherwise catalyze oxidative degradation of fibers and increase consumption of bleaching agents. This improves pulp brightness stability, protects cellulose and reduces unwanted side reactions during cooking and bleaching stages.
• In hydrogen-peroxide bleaching, HPAA performs as a stabilizer by removing catalytic transition metals that accelerate peroxide breakdown. By maintaining controlled peroxide activity, HPAA produces higher brightness with less fiber damage and a smoother bleaching profile. During papermaking, HPAA stabilizes process water by controlling hardness and metal ions that contribute to deposits on felts, wires and paper-machine rolls. It also enhances dispersion of fillers, fines and pigments in white-water loops, resulting in better sheet formation, cleaner machine surfaces and fewer papermaking defects.

Textile and Dyeing Industry

• HPAA contributes to textile pretreatment, bleaching and dyeing processes by removing metal ions that disrupt dye stability and peroxide performance. In pre-chelation steps, HPAA eliminates Fe, Cu and Ca ions from process water, minimizing shade variation, spotting and uneven dyeing. By reducing the impact of hardness ions, HPAA ensures that reactive dyes, vat dyes, sulfur dyes and acid dyes behave consistently, giving smoother and more reproducible dyeing results.
• In peroxide bleaching, HPAA slows premature peroxide decomposition by chelating catalytic metals, enabling efficient bleaching at temperatures around 90–100 °C and alkaline pH. This leads to improved whiteness and lower fiber degradation. HPAA is also incorporated into scouring and refining agents, where its chelating action prevents metal-catalyzed oxidation of natural impurities, supporting better fabric absorbency and cleaner surfaces for subsequent dyeing. When used in dye baths, HPAA enhances dye penetration and prevents formation of insoluble dye-metal complexes that cause dullness or streaking.

Procesamiento de metales y tratamiento de superficies

• In metal cleaning, HPAA is used with organic acids and surfactants to remove scale, rust and oxide films from steel, copper alloys and other metal surfaces. Its phosphonocarboxylic structure provides both strong metal-complexation and dispersion capability, helping detach deposits and hold them in suspension so they do not re-adhere. These cleaning systems often operate at 50–60 °C, allowing HPAA to dissolve mineral fouling efficiently with minimal corrosion of the base metal when combined with appropriate corrosion inhibitors.
• HPAA also plays a role in rust prevention and conversion-coating processes. By interacting with metal ions on the surface, HPAA helps form uniform, compact protective films that slow corrosion by limiting oxygen and moisture penetration. In phosphating and passivation baths, HPAA contributes to improving coating uniformity and adhesion, enhancing subsequent paint or plating performance. In electroplating and metal finishing, HPAA acts as a low-level complexing agent that helps stabilize bath chemistry, moderate metal ion activity and support fine-grained, smooth deposition.

Household and Personal-Care Industry

• HPAA is valued in detergent and cleaner formulations as a low-phosphorus chelating and stabilizing ingredient. In liquid laundry detergents, HPAA binds hardness ions to maintain surfactant performance, improve stain removal and reduce soil redeposition on fabrics. It also stabilizes liquid products by preventing metal-catalyzed oxidation of dyes, fragrances and sensitive actives. In dishwashing liquids, HPAA assists in removing limescale residues from dishes and sinks while preventing metal-ion induced cloudiness, streaking and oxidation of the detergent itself.
• In personal-care products such as shampoos, body washes and hand soaps, HPAA at low concentrations controls trace metals in the water phase and formulation. This protects color stability, viscosity and fragrance integrity while reducing hardness-related interactions that can affect foaming and rinsability. In bathroom and kitchen cleaning sprays, HPAA enhances removal of limescale, soap scum and metallic deposits on tiles, glass and metal surfaces.

Electronics Industry

• HPAA serves important functions in semiconductor cleaning, CMP slurries and PCB fabrication. In wafer cleaning, HPAA complexes metal ions and assists in removing oxides and micro-particle contaminants without damaging delicate circuit patterns. In CMP slurries containing ceria or silica abrasives, HPAA acts as a chelating component that stabilizes metal ions released during polishing, regulates slurry pH, and maintains abrasive dispersion, contributing to controlled removal rates and low-defect planarization.
• In PCB manufacturing, HPAA is used in cleaning, etching and plating baths to control metal-ion levels and stabilize bath chemistry. By influencing metal-complex equilibria, HPAA improves line definition, deposit uniformity and adhesion of subsequent metallization layers. In ultra-pure electronic cleaners, small amounts of HPAA in high-resistivity water help maintain extremely low ionic contamination levels required for advanced electronic devices.

Other Application Fields

• HPAA is used in various chemical processes as a reaction-control additive, where it chelates trace metals that trigger unwanted side reactions, discoloration or catalyst poisoning. In agriculture, HPAA is included in water-soluble fertilizers and pesticide formulations to keep micronutrients soluble and prevent metal-induced degradation of active ingredients. In the oil and gas sector, HPAA improves scale and corrosion control in produced-water systems, pipelines and heat exchangers operating under harsh salinity and temperature conditions. In new-energy applications, HPAA is used in solar-panel cleaning formulations and in certain battery and electrolyte systems to stabilize metal ions and improve durability.
