Benzalkonium bromide, tseem hu ua chlorhexidine thiab benzyl bromide, yog quaternary ammonium cationic surfactant broad-spectrum fungicide nrog cov nyhuv bactericidal muaj zog thiab sai, tsis muaj tshuaj lom, tsis khaus rau daim tawv nqaij thiab cov ntaub so ntswg, nkag mus rau hauv lub cev zoo, thiab tsis muaj...

xeb rau cov hlau thiab cov khoom siv roj hmab. Benzalkonium bromide tuaj yeem tua tau ntau yam kab mob Gram-positive, Gram-negative thiab qee yam fungi uas tsis tsim cov noob. Nws muaj zog nkag mus thiab permeability, uas pab tshem tawm cov kab mob uas nyuam qhuav nkag mus rau hauv cov ntaub so ntswg; nws tsis yog corrosive thiab khaus, tsis muaj kev puas tsuaj rau cov ntaub so ntswg, tsis cuam tshuam rau kev kho cov ntaub so ntswg, tsis ua rau muaj qhov caws pliav ntau ntxiv, thiab tsis muaj kev phiv tshuaj lom rau lub cev.

Cov khoom siv tshuaj lom neeg Cov khoom no yog cov khoom tsis muaj xim lossis daj daj lossis colloid. Melting point 46 ~ 48 ℃, flash point (Fp) ntau dua 110 ℃. Yooj yim yaj hauv dej lossis ethanol, nrog rau qhov tsw qab thiab saj iab heev. Muaj ntau cov ua npuas ncauj thaum nws raug co hnyav. Siv Cov khoom no muaj cov kab mob zoo heev thiab ntxuav tau. Nws tsis muaj kev cuam tshuam rau cov hlau thiab tsis ua rau cov khaub ncaws puas. Nws yog siv los ua tshuaj tua kab mob hauv tshuaj. Nws yog siv los ua tshuaj tua kab mob hauv dej hauv cov teb roj.
