Effective, Economical Metal Ion Control
Uncontrolled metal ions in your product or process can eat away profits by causing scaling, chemical degradation, discoloration, precipitation, emulsion instability, rancidity, and a host of other problems. The presence of metal ions can cause a number of unique challenges that formulators must overcome, such as:
- Cleaning and laundry products rendered ineffective
- Reduce bleaching efficiency and cause brightness reversion in pulp and paper processing
- Scaling and sludge in water system
- Shortened shelf-life and reduced performance in beauty and personal care products
- Food and beverage products are vulnerable to spoilage
Dow chelating agents provide an effective, economical solution to renders in active trace amounts of metal ions such as iron, copper and zinc. These products produce stable complexes with metal ions and generally provide the most effective control for related challenges. Some additional benefits of Dow Versene product line includes:
- Effective at low concentrations, driving down material and operational costs
- Predictable and proven performance
- High thermal stability
- Chemical and pH stability
- Resistance to bacterial or mold breakdown
