- Product Introduction
1. Product Information
Polyhexamethylene guanidine (PHMG) is named after its chemical structure containing bioactive alkyl guanidine. It is widely used in various fields due to its excellent characteristics, such as high stability and good biological activity.
a. Long-term inhibition: Colorless, odorless; safe to use.
b. Broad-spectrum bactericidal: Low effective concentration; fast action; stable properties; excellent water solubility; can be used at room temperature.
c. Long-lasting effect: PHMG is a stable polymer that does not evaporate or decompose, allowing it to be stored for an extended period. PHMG solution can form a polymer layer on the surface of objects after drying, maintaining the disinfection effect and preventing secondary contamination.
d. Safety: PHMG is a high-molecular-weight polymer, making it less likely to be absorbed by the tissues of higher organisms, resulting in minimal impact on higher biological cells. Additionally, PHMG is proven to naturally degrade without causing environmental pollution.

3. Applications
01. Everyday Disinfection:
Can be used for home and environmental disinfection, surface disinfection of objects, and hand disinfection. Effective against bacteria like E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, as well as common fungi and molds.
02. Aquaculture:
Environmentally friendly, broad-spectrum bactericidal, low usage concentration, effective against harmful microorganisms, including pathogenic bacteria and viruses in water bodies, improving water quality.
03. Agriculture, Fruits, and Flowers:
Quickly inhibits various agricultural bacteria and fungi. Bacteria are less likely to develop resistance, thus providing a long-term antibacterial effect. It's safe and environmentally friendly, containing no irritants like iodine, chlorine, or aldehydes, and leaving no heavy metal residues.
04. Livestock Farming:
Effective inhibition of common bacteria in agricultural settings. Well-tolerated by dairy cows, friendly to cow skin and mucous membranes. Suitable for environmental disinfection in livestock farming.
05. Skin Disinfection:
PHMG is a cationic polymer that primarily works by dissolving lipids, altering bacterial cell membrane permeability, and disrupting bacterial metabolism. It has a broad antibacterial spectrum and is friendly to the skin, providing rapid disinfection.
06. Water Treatment:
Broad-spectrum bactericidal, effective, and long-term inhibition of algae growth. Widely used in areas such as landscape water, industrial circulating water, and oilfield reinjection water treatment. Effective in controlling algae growth when used in shock doses, and higher doses can be used for heavy algae growth.
