Description

Ammonium 2-Phenylphenate is the ammonium salt of 2-phenylphenol, a compound valued for its biocidal and preservative properties. This product is essential for formulators requiring a stable, water-soluble derivative of ortho-phenylphenol for effective microbial control. It is primarily utilized in industrial and agricultural sectors where robust, long-lasting protection against fungi, bacteria, and algae is critical.

Application

• Industrial Preservative: Used in the formulation of metalworking fluids, adhesives, paints, and polymer emulsions to prevent microbial spoilage and extend shelf life.
• Agricultural Fungicide: Acts as an active ingredient or component in post-harvest treatments for fruits and vegetables to control mold and decay.
• Wood Protection: Incorporated into wood preservative formulations to safeguard against fungal rot and insect damage.
• Disinfectant & Sanitizer: A key component in institutional and industrial disinfectant formulations for hard surface sanitation.
• Textile & Leather Processing: Serves as a biocide in processing baths to prevent microbial degradation of materials.
• Cooling Water Treatment: Used in industrial water systems as an algicide and slimicide to maintain system efficiency.
