【Physical and Chemical Properties】

【Antibacterial Principle】

◆ PHMBGuanidine possesses high reactivity, enabling polymers to become positively charged, which easily attracts negatively charged bacteria and viruses. This吸附 inhibits their reproductive capabilities and splits, rendering them sterile. Additionally, the film formed by the polymer blocks the respiratory pathways of microorganisms, causing them to asphyxiate and die rapidly.

◆PHMBAnother active ingredient, hydrochloric acid, enhances the antibacterial effectiveness.

【Toxicity test】

◆ Toxicological tests indicatePHMBAcute oral toxicity test with mice showed no adverse reactions or deaths in the animals, and the same applies to both male and female mice.LD50>5000 mg/kgWeight, according to the acute toxicity classification standards, falls into the practically non-toxic category.

◆ One-time skin irritation test for domestic rabbits: Single contact with rabbit skinPHMBLater, the stimulation points value0Non-irritating.

◆Rabbit Eye Irritation Test: The score of the rabbit's ocular mucosal (cornea, iris, conjunctiva) irritation response is0Non-irritating.

◆Guinea Pig Skin Sensitization Test After24H,48HGuinea pig skin test areas showed no significant erythema or edema, with a sensitization rate of0This product is categorized as a mild allergen.

◆Similarly,PHMBCurrently considered a safe and non-toxic antibacterial disinfectant.

【PHMB Contraindications】

◆ Non-ionic, anionic, and amphoteric surfactants are fully compatible, such as polyoxyethylene fatty alcohols EtherAEO, betaine, ammonium oxide, EO/PO block copolymers, etc.

◆ PHMB has cationic properties. When anionic compounds such as soap are present, they form insoluble salts, leading to a decrease in activity. In addition, it is not compatible with phosphates, strong alkalis, and strong oxidizing agents.

Its compatibility is also limited.

◆ Completely compatible without chelating agents.EDTA (Ethylene diamine tetraacetic acid), NTA (Nitrilotriacetic acid)

◆ Non-polar solvents fully miscible, such as ethanol, diethylene glycol, and diethylene glycol ether.

◆ Incompatible with inorganic acids and many organic acids.HCI, H3PO4, Glycolic Acid

◆ Not fully compatible with cellulose thickening agents.HPC，HEC，HPMC；

◆ Non-pigmented is compatible over a wide range, such as with nitrogenous and sulfonate types.
