Product Description
This high-molecular-weight polymeric disinfectant contains no less than 20% active ingredient and has a pH value between 4.0 and 6.5 when measured at 25°C. Due to its large molecular size, Polyhexamethylene biguanide 20% solution is poorly absorbed by human tissues, making it suitable for applications involving direct human contact. Laboratory studies have confirmed its favorable safety profile: in vitro tests showed no cytotoxic effects, and skin irritation trials on rabbits and human volunteers indicated no adverse reactions.

Key Benefits
This 20% polyhexamethylene biguanide liquid demonstrates remarkable heat resistance, retaining its antimicrobial efficacy even after being exposed to 280°C for 15 minutes. Its mechanism of action is physical rather than chemical: the positively charged polymer chains bind to negatively charged microbial surfaces, leading to cell membrane disruption and metabolic arrest. This mode of action effectively prevents the development of microbial resistance. Additionally, the product is non-corrosive, generates little foam, and rinses off easily-ideal for processes where minimal residue is desired.
Primary Applications
Polyhexamethylene biguanide 20% solution finds use across a diverse range of sectors. It is a common ingredient in contact lens care solutions, cosmetics, and medical disinfection products (including skin and mucous membrane antiseptics). Other applications include sanitizing fruits and vegetables, treating air and drinking water, maintaining swimming pools, and incorporating into papermaking and sanitary products such as sanitary napkins. It is also suitable for textile treatment and routine surface disinfection.
Frequently Asked Questions (FAQ)
Q: What dilution is recommended for routine disinfection?
A: Typically, a final concentration of 0.05% to 0.5% is effective, which corresponds to a 200- to 2000-fold dilution of the 20% solution. However, the optimal concentration should be determined based on your specific process conditions.
Q: How should this product be stored?
A: Keep the container tightly sealed in a cool, dry, well-ventilated area away from direct sunlight and heat sources. This prevents moisture pick-up and maintains product quality.
Q: Can this product be mixed with other chemicals?
A: Avoid combining it with anionic surfactants (e.g., common soaps), as this may cause precipitation and reduce the disinfectant's effectiveness.
