- Sterilization effect
The temperature under normal climatic conditions has little effect on its sterilization effect. The sterilization effect is enhanced under alkaline conditions, and the acidic conditions are weakened. Compatible with cationic or nonionic surfactants, anionic surfactant can reduce its disinfection effect, the concentration below 0.001% has little effect.
The sterilization rate of 0.02% polyhexamethyleneguanidine against Escherichia coli, Staphylococcus aureus and Candida albicans are all 100%;
The sterilization rate of 0.05% polyhexamethylene guanidine against Neisseria gonorrhoeae is 100%. The on-site sterilization test has a sterilization rate of 99.8% on the surface of objects, which is greater than the 90% sterilization index prescribed by the state. The on-site sterilization test has a sterilization rate of 97.65% on the palm surface, which is greater than the 90% sterilization index prescribed by the state.
- Application
Widely used in medical and health, daily chemicals, textiles, paper, wet wipes, animal husbandry, breeding, aquatic products, plastics, agriculture, water treatment and other fields
- Usage and precautions
Dilute directly with purified water or use with other additives. The reference dosage is 0.05% ~ 0.5% (w / w).
(1) Avoid mixing with soap, washing powder and other anionic detergents.
(2) When this product is diluted in an aqueous solution, it must be stirred evenly.
* Because the product is used in different fields, the usage and dosage of the product are quite different, it is recommended to use it under the guidance of the company’s professional technicians.
