Usage: Disinfection, sterilization, mouldproof.This product antibacterial, of gram-positive bacteria, gram-negative bacteria, yeast and fungi were killing effect.Widely used in daily chemical industry, water treatment area, medical and hygienical fields etc. Commonly used as the biocide mildewcide of female lotion and moist wipes, and as the antiseptics of fruit, vegetable and aquatic product. Also could be used as flocculation sanitizer in wastewater treatment. Comparison with PHMG: the bacteriostatic effect of PHMB to Straw coli, Saccharomyces cerevisiae and aspergillus niger is higher than that of PHMG. Because of the polymer structure of PHMB, bacteria cannot be resistant to it. And this has also been proved with experiment by international authoritative test organization.
