Paper Biocide

We Dadia Chemical Industries are Manufacturers, Suppliers, Exporters, Dealers, Traders of Preservative Paper Biocide. Preservative Paper Biocide is an antimicrobial agent used to prevent the growth of bacteria, fungi, and molds in paper products. It is applied during paper manufacturing or to finished paper products to extend shelf life, maintain quality, and prevent contamination.

Chemical Composition:

Active Ingredients: The biocidal components typically include:
Isothiazolinones (e.g., methylisothiazolinone, chloromethylisothiazolinone)
Benzisothiazolinone or other organic biocides
Phenolic compounds
Quaternary Ammonium Compounds (e.g., benzalkonium chloride)
Copper or silver ions (for long-term antibacterial/antifungal effects)
Formaldehyde-releasing agents (less common today)

Function and Uses:

Microbial Growth Inhibition: Prevents spoilage and degradation by bacteria, fungi, and molds.
Mold and Fungi Prevention: Protects paper in humid environments from mold and mildew growth.
Paper Product Preservation: Maintains quality of paper products during storage and use.
Antibacterial Action: Reduces risk of contamination with harmful bacteria in sensitive environments.
Prevention of Paper Degradation: Protects fibers from enzymatic breakdown by microbes.
Improvement in Storage and Transport: Ensures integrity during shipping and storage, especially in damp conditions.

Properties:

Appearance: Liquid or powder form that can be mixed with pulp or applied to finished paper.
Mode of Action: Disrupts microbial membranes, inhibits DNA/RNA synthesis, or enzymatic processes.
Longevity: Protection may last for the life of the paper or degrade over time with UV or heat exposure.

Safety and Environmental Impact:

Safety: Depends on the chemicals used; some may be toxic or irritant. Proper PPE recommended during handling.
Formaldehyde-releasing biocides may cause allergic reactions or respiratory issues.
Isothiazolinones can be allergenic or irritant to skin, eyes, or mucous membranes.
Non-biodegradable biocides may contribute to water and soil pollution. Biodegradable and eco-friendly alternatives are preferred.

Applications:

Packaging: Food, medical, and shipping materials requiring microbial protection.
Office and Specialty Papers: Libraries, archives, or long-term preservation needs.
Medical and Hygiene Products: Paper towels, napkins, tissues, and medical papers.
Printing Paper: Newspapers, books, and magazines exposed to high humidity or temperature variations.
