Polyhexamethyleneguanidehydrochloride PHMG

PHMG performance advantages

(1) Broad-spectrum sterilization; low effective concentration; fast action speed; stable properties; excellent performance of being easily soluble in water; can be used at room temperature;

(2) Long-term antibacterial, no side effects; non-corrosive; colorless and odorless; non-flammable and non-explosive, safe to use;

(3) Long-lasting: Because polyhexamethylene guanidine is a stable polymer, it is not volatile and does not decompose, so it can be stored for a long time, and after the polyhexamethylene guanidine solution is dried, it can form a The thin polymer layer of the disinfectant can maintain the best state of the object after sterilization and prevent secondary pollution of the object. Under normal circumstances, various surfaces treated with polyhexamethylene guanidine aqueous solution will remain sterile for three months.

(4) Non-toxicity: Because polyhexamethylene guanidine is a high molecular polymer, it is not easily absorbed by animal tissues, which greatly reduces the toxicity of polyhexamethylene guanidine and makes polyhexamethylene guanidine effective in higher organisms. The cells have basically no effect. In addition, experiments have proved that polyhexamethylene guanidine can be degraded naturally and will not cause pollution to the environment.

(5) No skin irritation: Shanghai Municipal Center for Disease Control conducted an experimental study of polyhexamethylene guanidine on skin with rabbits. The conclusion is that a 0.2% solution has an integral value of 0 for skin irritation and no skin irritation. (Judgment criteria: the lower the integral value, the lower the irritation.

Chemical and physical properties

Antibacterial principle:

Guanidine group has high activity, can make the polymer become positively charged, it is easy to be adsorbed by all kinds of bacteria and viruses that are negatively charged, thereby inhibiting the division function of bacteria and viruses, causing them to lose their reproductive ability. The formed film blocked the breathing channels of microorganisms, causing the microorganisms to suffocate and die quickly.

Another active ingredient, hydrochloric acid, enhances the bactericidal ability.

Dosage:

Directly dilute with purified water or use in combination with other additives. The reference dosage is 0.05%~0.5%(w/w). Since the usage and dosage of the product are quite different when the product is applied in different fields, it is recommended to use it under the guidance of our company's professional technicians.

Application:

Polyhexamethyleneguanidine (PHMG) is effective against Escherichia coli, Staphylococcus aureus, Candida albicans, Neisseria gonorrhoeae, Salmonella, Pseudomonas aeruginosa, Listeria, Shigella, Aspergillus niger, Brucella, Para Vibrio hemolyticus, Vibrio alginolyticus, Vibrio anguillarum, Aeromonas hydrophila, sulfate-reducing bacteria, iron bacteria, and saprophytes have a complete killing effect. It is suitable for sterilization, disinfection and algae elimination in industries such as skin, mucous membranes, fruits and vegetables, air, drinking water, swimming pools, general surfaces, papermaking, toilet paper, women’s sanitary napkins, clothing and aquaculture, animal husbandry, and tertiary oil extraction. In the agricultural field, it has good prevention, treatment and income-increasing effects on plant seed treatment and crop gray mold, sclerotinia, bacterial angular leaf spot, root rot, blight, grape anthracnose, felt disease, beetle, etc. . It can play a good role of flocculation and sterilization in the sewage treatment process.

Case application

1. Application of PHMG in aquaculture

Purpose: To clean up shrimp ponds and fish ponds, purify water quality, and prevent sea cucumbers, fish, and shrimp from getting sick

Method: Select part of the experimental fry, add 0.20~3.00mg/L according to the instruction, and put it every 15 days.

Conclusion: An aquaculture farmer has tested the company’s polyhexamethylene guanidine to verify that polyhexamethylene guanidine not only enhances water activity, purifies water, but also effectively decomposes feed waste, fish manure and other impurities in shrimp ponds and fish ponds. , Reducing the probability of sea cucumber, fish and shrimp diseases caused by baculovirus.

Note: Please consult our company’s professional and technical personnel for its antibacterial effect and proportion

2. Application in disinfection wipes

Purchase product: Polyhexamethyleneguanidine liquid 25% 5 tons

Purpose: Convenient to use, carry, and inhibit bacteria.
