Description

Dichlorophen CAS NO 97-23-4 is an organochlorine compound primarily recognized for its potent antimicrobial and preservative properties. This chemical is valued for its effectiveness in controlling microbial growth and preventing spoilage in various industrial systems. It serves as a critical functional ingredient for manufacturers in the water treatment, leather processing, and wood preservation industries, where reliable biocidal performance is essential.

Application

• Industrial Biocide & Slimicide: Used in cooling water systems, paper mills, and industrial process waters to control algae, fungi, and slime-forming bacteria.
• Leather Processing: Acts as a preservative and fungicide in the tanning process to protect hides and finished leather from microbial degradation.
• Wood Preservative: Incorporated into treatments for lumber and timber to provide protection against wood-decaying fungi and insects.
• Textile Protection: Applied to fabrics and textiles to impart mildew and rot resistance, especially in technical and outdoor applications.
• Adhesive & Polymer Preservation: Serves as a in-can preservative in water-based adhesives, paints, and polymer emulsions to extend shelf life.
• Disinfectant Formulations: Used as an active ingredient in the formulation of hard-surface disinfectants for institutional and industrial use.
