Description

Polyaminopropyl Biguanide is a high-performance polymeric biguanide compound widely recognized for its potent antimicrobial and preservative efficacy. Its primary value lies in its broad-spectrum activity against bacteria, fungi, and algae, coupled with excellent chemical stability and low toxicity. This makes it an essential ingredient for manufacturers in the personal care, water treatment, and industrial preservation sectors seeking reliable and safe biocidal solutions.

Application

• Personal Care & Cosmetics: A key preservative in shampoos, liquid soaps, wet wipes, and lotions to prevent microbial spoilage.
• Water Treatment: Used as a non-oxidizing biocide in industrial cooling water systems, swimming pools, and spas to control slime and algae.
• Disinfectants & Sanitizers: Formulated into hard surface disinfectants, fabric sanitizers, and healthcare cleaning products.
• Industrial Preservation: Protects aqueous-based functional fluids, adhesives, polymer emulsions, and metalworking fluids from biodeterioration.
• Textile & Leather: Imparts durable antimicrobial properties to fabrics, fibers, and leather goods.
• Paints & Coatings: Serves as an in-can preservative for water-based paints and coatings to extend shelf life.
