VERSENE chelating agents can effectively control metal ions in a wide variety of applications. They are suitable for both wet and dry applications and can be used to target particular problem metals or specific pH requirements.
Cleaning Products
VERSENE chelating agents help to control water hardness ions that can interfere with the performance of household, industrial, and institutional cleaning products. They help maintain clarity, retard rancidity, prevent streaking, remove hard water soap/film, and prevent scale in a wide variety of cleaner formulations including hard surface cleaners, laundry detergents, liquid soaps, germicidal and anti-bacterial cleansing preparations, and vehicle cleaners. They are USDA approved for many indirect food uses (such as sanitizing solutions). VERSENE chelating agents can also protect carpet cleaning machines and other cleaning equipment from failure due to scale build-up.
Food and Beverage
The ability to control metal ions in aqueous systems is vital to the success of many food and beverage applications and processes. Flavor, color, clarity, stability, and vitamin content of foods and beverages are sensitive to metal-catalyzed oxidative breakdown. VERSENE CA and VERSENE NA chelating agents can be used to control those metal ions to improve product quality, enhance consumer appeal, and extend shelf-life. Effective at low concentrations, chelating agents are frequently more economical than citrates or phosphates.
Metalworking
VERSENE chelating agents are employed extensively in metalworking areas, from the preparation and cleaning of metal surfaces to the final finishing and plating operations. The four major uses for VERSENE chelating agents in metalworking are in surface preparation, metal cleaning, metal plating, and in metalworking fluids.
Oilfield Applications
Chelating agents are used in several operations in the drilling, production, and recovery of oil. They can prevent plugging caused by iron precipitation during stimulation and fracturing. VERSENE chelating agents are used for scale removal and prevention on well casings. And they can prevent scaling in boilers used for enhanced oil recovery steam flooding.
Personal Care Products
VERSENE chelating agents are used in almost every type of personal care formulation to increase effectiveness and improve stability, improving consumer acceptance. VERSENE chelating agents can be used in bar and solid soaps; bath preparations; creams, oils, and ointments; hair preparations, and shampoos.
Pharmaceutical
VERSENE NA chelating agent is manufactured as a pharmaceutical-grade product to comply with USP/NF/FCC requirements, and provides excellent metal ion control in pharmaceutical applications. VERSENE NA chelating agent is used for drug stabilization, helping to maintain potency of active ingredients and to stabilize colors and flavors.
Polymerisation
VERSENE chelating agents are widely used in the polymerization of suspension, emulsion, and solution polymers. They can be employed both in polymerization reactions and finished polymer stabilization.
Pulp and Paper
VERSENE chelating agents are important processing tools in the pulp and paper industry. These water-soluble products are ideal for pulping since water is the processing medium. They protect bleach potency by curbing metal-catalyzed bleach degradation; and can actually lower your bleaching costs by maximizing bleaching efficiency. VERSENE chelating agents are approved for use in many indirect food uses (such as food wrap paper) and provide the opportunity for silicate-free peroxide bleaching. Specific uses of VERSENE chelating agents in pulp bleaching include peroxide bleaching, hydrosulfite bleaching, brightness reversion control, and scale and pitch control.
Scale Removal and Prevention
VERSENE chelating agents are used successfully in scale removal to clean calcium and other types of scale from boilers, evaporators, heat exchangers, filter cloths, and glass-lined kettles. Working in combination with other materials, they can also work effectively in scale prevention.
Textiles
VERSENE chelating agents are important tools in all phases of textile processing, and particularly in the scouring, dyeing, and color stripping stages.
Water Treatment-Hardness Control
Chelating agents provide excellent control of scale-forming calcium and magnesium in open circulating cooling systems. VERSENEX CSI inhibitor provides a unique combination of performance properties, including excellent carbon steel corrosion protection; superior CaCO3 controls; yellow metal protection without supplemental inhibitors; superior high-cycle performance; and excellent recovery from pH excursions and other severe operating conditions.
