Application

C18-EB is used as a broad-spectrum bactericide, algicide, and surface disinfectant in industrial water treatment.

1. Water Treatment & Oilfield Applications
Functions as a highly effective bactericide, algicide, and slime control agent in industrial cooling water systems, paper mills, and oilfield injection operations. It disrupts microbial cell membranes, preventing the formation of biofilms and biological slime that can clog pipelines and reduce heat exchange efficiency. This compound is stable under harsh conditions and compatible with other treatment chemicals, ensuring reliable performance in both freshwater and saline environments. Regular use helps maintain system cleanliness, extends equipment lifespan, and reduces downtime caused by microbiological fouling.
2. Textile Industry
Acts as a cationic softening agent and antistatic agent for synthetic fibers such as acrylic, polyester, and nylon. It adsorbs onto fiber surfaces, neutralizing negative charges and reducing static electricity during processing, cutting, and end-use. This treatment imparts a smooth, soft handfeel to fabrics without affecting their natural appearance or breathability. It also improves fiber-to-fiber lubrication, minimizing mechanical damage during weaving and finishing. The product is easily dispersible in aqueous baths and compatible with most textile auxiliaries.
3. Disinfectants & Sanitizers
Widely used as an active ingredient in formulating hospital-grade disinfectants, household sanitizers, and industrial cleaning agents. It exhibits broad-spectrum antimicrobial activity against Gram-positive and Gram-negative bacteria, fungi, algae, and certain viruses. The compound works by disrupting the lipid bilayer of microbial cell membranes, leading to cell lysis and death. It remains stable in diluted solutions and is effective across a wide pH range, making it suitable for surface disinfection, equipment sanitation, and water purification applications.
