Description

Poly(Methylene-Co-Guanidine), Hydrochloride is a polymeric biguanide compound, a versatile and effective cationic biocide. This product matters for its broad-spectrum antimicrobial activity, making it a critical component in formulations requiring preservation and disinfection. Industries such as water treatment, personal care, and industrial preservation rely on its efficacy to control microbial growth and ensure product stability.

Application

• Industrial Water Treatment: Used as a non-oxidizing biocide in cooling towers, process water, and paper mill systems to control algae, bacteria, and slime.
• Personal Care & Cosmetics: Serves as a preservative in shampoos, creams, and lotions to prevent microbial spoilage and extend shelf life.
• Disinfectants & Sanitizers: A key active ingredient in formulations for hard surface disinfectants, swimming pool sanitizers, and food contact surface cleaners.
• Textile & Leather Processing: Applied as an antimicrobial agent to impart hygienic properties to fabrics and prevent biodeterioration.
• Adhesives & Paints: Incorporated as an in-can preservative to protect water-based formulations from bacterial and fungal degradation.
• Oilfield Applications: Used in drilling muds and fracturing fluids to control sulfate-reducing bacteria (SRB) and prevent microbiologically influenced corrosion (MIC).

Quality Control

Our Poly(Methylene-Co-Guanidine), Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous testing to ensure consistent purity, potency, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, viscosity, and microbiological efficacy are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture which may affect product performance.
