Character

Polyhexamethylene biguanide hydrochloride, abbreviated as PHMB, is a long-acting disinfectant and sterilant, which has two forms of powder and aqueous solution, generally 20% aqueous solution. The guanidinium group of Polyhexamethylene biguanide hydrochloride(PHMB) has high activity and can make the polymer positively charged, which is easily adsorbed by various negatively charged bacteria and viruses, thereby inhibiting the bacterial virus's ability to split and make it lose its ability to reproduce In addition, the film formed by the polymer blocks the respiratory channels of the microorganisms, causing the microorganisms to die quickly. Polyhexamethylene biguanide hydrochloride(PHMB) is capable of killing bacteria, fungi and yeast. It acts on the cell wall system and / or cell membrane system of bacteria, fungi, algae, and combines with the cell membrane phospholipid compound, quickly penetrates their membrane system, causes the outflow of the intracellular material of the bacteria, and inhibits certain enzyme activities attached to the cell , So as to achieve antibacterial and antifungal effects. Polyhexamethylene biguanide hydrochloride(PHMB) has low toxicity, LD50> 2500 mg / kg, and can be used for a long time.

Compared with polyhexamethylene guanidine, Polyhexamethylene biguanide hydrochloride(PHMB) has better antibacterial effect on fungi and yeasts, with more efficient, safe, stable, long-acting antibacterial effect, easy to use, and environmentally friendly.

Usage

Polyhexamethylene biguanide hydrochloride(PHMB) has the functions of disinfection, sterilization and mildew prevention. It is a broad-spectrum antibacterial agent, and it can kill Gram-positive bacteria, Gram-negative bacteria, fungi and yeast. Polyhexamethylene biguanide hydrochloride(PHMB) can be widely used in daily chemical industry, water treatment, medical and health fields.

Application

Lotion: Polyhexamethylene biguanide hydrochloride(PHMB) is used as the main sterilization ingredient in the compound hand-washing disinfectant. When the content of Polyhexamethylene biguanide hydrochloride(PHMB) is 250-300 mg / l, it has a good killing effect on cell propagules and yeasts.

Swimming pool disinfection: Polyhexamethylene biguanide hydrochloride(PHMB) is non-irritating when used in swimming pool disinfection, and its usage is 10-50 ppm. Polyhexamethylene biguanide hydrochloride(PHMB) has a certain repair function on the skin.

Medicine: Polyhexamethylene biguanide hydrochloride(PHMB) can be used for antibacterial gauze and antibacterial dressing. Gauze or dressings containing 0.2% Polyhexamethylene biguanide hydrochloride(PHMB) antibacterial ingredients can be used for surgical wounds and wound dressings to prevent bacterial infection and breeding. Polyhexamethylene biguanide hydrochloride(PHMB) can repair damaged skin cells and accelerate metabolism.

Daily care products: Polyhexamethylene biguanide hydrochloride(PHMB) can be used for antibacterial preservation of disposable wet tissues, wet towels, napkins, antibacterial hand sanitizer; used in lens disinfectant

Aquaculture: Adding Polyhexamethylene biguanide hydrochloride(PHMB) to the aquatic water system can inhibit bacteria in the water system and prevent aquatic diseases such as red legs, rotten eyes and rotten gills caused by bacteria. At the same time, it can also enhance the activity of water, reduce ammonia and phosphate in the water, control the growth of algae, naturally balance the ecosystem of the breeding pond, and play a good role in the prevention and treatment of diseases. Polyhexamethylene biguanide hydrochloride(PHMB) is recommended to add 1 to 5 ppm to prevent The effect of disease treatment. When the disease of fish and shrimp is serious, the dosage can be increased to 15 ppm.

Textile: Polyhexamethylene biguanide hydrochloride(PHMB) can be used for antibacterial finishing of textiles. Due to its good heat stability, it can be added to melt spinning solution to make antibacterial synthetic fibers. Polyhexamethylene biguanide hydrochloride(PHMB) can also be used in antibacterial laundry liquid, non-irritating to the skin, washed clothes are not harmful to the human body, it does not produce odor after use.
