Applications of 26172-55-4
| Industry | Application | Process |
|---|---|---|
| Water Treatment | Biocide and algaecide for controlling microbial contamination in industrial recirculating cooling water, oilfield reinjection water, and paper mill white water systems | Added to water systems, where oxidative action disrupts microbial cell structures to inhibit bacterial, fungal, and algal growth |
| Coatings & Paints | Preservative and anti-mildew agent to prevent microbial degradation of coatings during storage and after film formation | Incorporated during coating manufacturing, typically in combination with other preservatives, to ensure antimicrobial efficacy in both wet and dry films |
| Metalworking Fluids | Microbial control agent to prevent spoilage and deterioration of cutting fluids, grinding fluids, and similar formulations due to bacterial growth | Directly dosed into metalworking fluids to maintain pH stability and extend fluid service life |
| Paper Industry | Pulp preservative and white water biocide to prevent slime formation and biofilm buildup on equipment | Dosed during pulp preparation or in the white water recirculation system to control proliferation of both aerobic and anaerobic microorganisms |
| Personal Care Products | Preservative for shampoos, body washes, skincare products, and similar formulations to prevent product spoilage | Added at low concentrations (typically ≤15 ppm) to inhibit growth of Gram-positive and Gram-negative bacteria as well as yeasts |
| Adhesives & Sealants | Preservative and anti-mildew additive to prevent microbial degradation during storage and application | Incorporated during formulation to protect organic components from bacterial and fungal attack |
| Oil & Gas | Oilfield biocide for controlling sulfate-reducing bacteria and other harmful microorganisms in fracturing fluids, drilling fluids, and reinjection water | Injected batchwise or continuously into treatment systems to mitigate microbially induced corrosion (MIC) and hydrogen sulfide generation |
