Polyaminopropyl Biguanide (PAPB) is rapidly gaining recognition across industries for its multifaceted role as a high-performance antiseptic, preservative, and disinfectant.

Provided by AquigenBio, PAPB delivers robust efficacy and safety, making it a preferred choice for professionals in pharmaceuticals, healthcare, cosmetics, agriculture, industry, and more.

What is Polyaminopropyl Biguanide (PAPB)?

Polyaminopropyl Biguanide is a synthetic polymer, chemically identified as C5H14N6 (CAS No: 133029–32–0), featuring multiple biguanide functional groups linked by propyl bridges.

The structure imparts distinctive properties, such as water solubility and strong cationic charge, enabling which it to interact effectively with and neutralize microorganisms.

Key Features and Benefits

1. Broad-Spectrum Antimicrobial Activity: PAPB is effective against bacteria, fungi, algae, and certain viruses. Its mode of action disrupts microbial cell membranes, rendering pathogens inactive and ensuring a high degree of safety for end users.

2. Low Toxicity and High Safety Profile: Scientific safety assessments confirm that PAPB is safe when formulated appropriately in cosmetics and healthcare products. Unlike harsh alternatives, it is nonirritating and nonsensitizing at recommended concentrations.

3. Versatility Across Applications: Its efficacy and low cytotoxicity compared to related polymers enable usage in sensitive applications such as wound care, contact lens solutions, skin and surface disinfectants, and cosmetics.

4. Stability and Preservative Power: PAPB maintains product integrity by inhibiting microbial growth, extending shelf life and preserving quality even in high-humidity environments.

Industrial, Healthcare, and Cosmetic Applications

1. Healthcare and Medical

  • Wound Care: PAPB is used in wound dressings and irrigations for managing chronic wounds, burns, and ulcers. It reduces infection risks without interfering with tissue regeneration, supporting faster and cleaner healing.

  • Medical Device Sterilization: Its compatibility with various materials makes it suitable for disinfecting catheters, surgical instruments, and endoscopes, thus minimizing hospital-acquired infections.

  • First Aid and Routine Antisepsis: Ideal for surface disinfection, routine antiseptic procedures during minor incisions or catheterization.

2. Cosmetics and Personal Care

  • Preservative in Cosmetics: PAPB is an efficient preservative, used in rinse-off and leave-on products like shampoos, creams, makeup, and skin cleansers. It not only maintains microbial safety but also cleans and sterilizes skin by neutralizing harmful microorganisms.

  • Contact Lens Solutions: It ensures eye safety by preventing microbial contamination in lens-cleaning formulas, reducing risks of infections such as Acanthamoeba keratitis.

  • Hair and Bath Products: Its gentle profile is suitable for use in hair care and bath products, preserving product freshness and safety throughout usage.

3. Industrial and Environmental

  • Water Treatment: PAPB is effective for treating swimming pools, spas, and industrial water systems, providing an alternative to chlorine- and bromine-based disinfectants.

  • Textile and Paper Processing: Used as a mildew-proofing and bacteriostatic agent, protecting materials from microbial degradation during manufacturing and storage.

  • Agriculture and Aquaculture: Its safety and efficacy support disinfection of livestock environments, fisheries, and aquaculture facilities, safeguarding animal and environmental health.
