Melting point 114-116 ° C. Nyob rau hauv 20 ° C, 1 gram yuav yaj nyob rau hauv 3 liv dej, thiab yaj hauv ib feem ntawm 95% cawv, soluble nyob rau hauv ether, benzene, terpenes, olefins, polyethylene glycol, non-volatile roj thiab alkali hydroxide kua. Nws yog dej ntub dej thiab muaj dej kub nyob ruaj khov.
Cov qauv ntawm 4-Chloro-3,5-dimethylphenol
PCMX yog ib qho ua tau zoo heev, dav-spectrum thiab muaj kev tiv thaiv kom tsis txhob muaj kev tiv thaiv tus kab mob qog neeg. Qhia los ntawm FDA, nws yog qhov kev xaiv zoo tshaj plaws rau kev kho kom zoo ntawm feem ntau cov kab mob Gram-positive thiab negative, fungi, pwm thiab hais txog. Nws yog non-toxic thiab non-irritative.
Tsab Ntawv 1: kev ua haujlwm ntawm PCMX
| Gram-positive kab mob | Bactericidal concentration / ppm | fungi | Bactericidal concentration / ppm |
| Staphylococcus aureus | 10 | candida albicans | 50 |
| Bacillus subtilis | 50 | saccharomycetes | 50 |
| Bacillus cereus | 50 | mold & saccharomycetes | 110 |
| fecal streptococcus | 20 | torula poov xab | 100 |
| Gram-negative kab mob | 40 | aspergillus niger | 1000 xyoo |
| Escherichia coli | 50 | Penicillium chrysogenum | 200 |
| proteus unlgaris | 100 | rhizopus nigricane | 100 |
| bacillus pyocyaneus | 1000 xyoo | mob hawb pob | 1000 xyoo |

Ua ib qho tshuaj tua kab mob, PCMX tsis yog tsuas yog siab npaum li cas, tab sis kuj muaj kev ruaj ntseg siab. Hauv kev tsom voos rau qhov muag thiab tawv nqaij ntawm cov nas nyob hauv cov kab mob hnyav ntawm LD50> 2g / kg, nws pom tias tsis muaj qhov voos. Nws qhia tau hais tias tsis haum thiab kev txhaum fab hnyav ntawm kev ua xua nrog kev mob hnyav ntawm LD50> 3g / kg. Yog li, PCMX yog lees paub tias tus neeg siv tshuaj qaug tshuaj lom neeg tsis haum, nws yog siv rau tej tawv nqaij - kev tiv tauj rau khoom, xws li kua ntxuav tes, xab npum, tshuaj zawv plaub hau thiab cov khoom siv ua tsis huv. Cov tshuaj siv li niaj zaus nyob rau hauv ntau cov kua tshuaj pleev: Cov xab npum 0.5-1 ‰, antibacterial hand sanitizer 1 ‰, tshuaj tua kab mob 4.5-5 ‰, yuav ua tau raws li qhov xav tau ntawm cov kab mob bactericidal.
Ib qho tseem ceeb ntawm kev siv PCMX yog rau kev txuag siv hauv qee cov tshuaj lam, xab npum, tshuaj tua kab mob, tshuaj tua kab mob, tshuaj ntxuav khoom; siv los ua yas txha ntawm cov khoom emulsions, tshuaj pleev ib ce, kua cawv, kua nplaum, txhuam, pleev, pleev xim thiab yas, nrog rau cov cua kub zoo thiab cov huab cua tsis haum. Vim yog muaj zog nyob hauv lub pob zeb, nws yog ib qho tshwj xeeb tshaj yog rau cov ntawv PVC thiab tsis sib thooj. Nws kuj tseem siv tau ua kom zoo nkauj ntawm textile, ntawv ua thiab tshuaj txhua hnub.
PCMX muaj kev ruaj ntseg zoo nyob rau hauv kev niaj hnub mob; tom qab ntev ntev cia, nws cov xim yuav tsaus, tab sis tsis poob kev ua si, uas yog ib qho tseem ceeb rau kev tua kab mob.
