Tsim tshwj xeeb rau cov dej-raws li kev tsim qauv, sodium ethylparaben sawv tawm rau nws qhov kev ua tau zoo hydrophilic. Nws dissolves tam sim ntawd nyob rau hauv li niaj zaus - dej kub thiab sib tov zoo nrog polar organic solvents, thaum tsis yaj nyob rau hauv oily tshuaj thiab ether -raws li non-polar solvents. Qhov no paraben ntsev derivative nta ruaj khov tshuaj zoo nyob rau hauv cov pa cia thiab raug mob. Nws tuaj yeem tiv taus siab -kub txheej txheem ntau lawm thiab ua kom ruaj khov antibacterial potency hauv nruab nrab thiab tsis muaj zog alkaline formula ib puag ncig. Qhov tseem ceeb, acidic tej yam kev mob uas tsis tshua muaj pH qhov tseem ceeb yuav ua rau cov khoom siv los nag, uas ua rau cov khoom siv khaws cia thiab tshuaj tua kab mob.
Qhov Zoo Tshaj Plaws
Tsis tas li ntawd, cov khoom lag luam muaj cov ntsiab lus tsis zoo thiab ua tiav daim ntawv pov thawj tsim nyog, ua kom muaj kev sib haum xeeb, tsis yog - khaus khaus thiab kev nyab xeeb daim ntawv thov raws li kev noj tshuaj.
Nruab nrog cov khoom siv tshuaj tua kab mob dav dav, sodium ethylparaben ua tau zoo tiv thaiv kev loj hlob ntawm ntau yam kab mob tsis zoo hauv dej- cov khoom lag luam.
Piv nrog rau cov dej khaws cia zoo tib yam, nws muab kev ruaj khov thiab ruaj khov tiv thaiv - tiv thaiv corrosion rau cov khoom tiav.
Featuring yooj yim dej solubility, cov khoom siv raw yuav tsum tsis muaj cov organic solubilizers ntxiv, ua kom cov haujlwm ua haujlwm zoo heev thiab tshem tawm cov kev phom sij zais xws li cov kuab lom thiab cov khoom ua kom khaus.
Nws ua tiav kev sib raug zoo nrog dej- raws li cov khoom tu tawv nqaij, cov tshuaj ntxuav tes txhua hnub, cov zaub mov ua kua thiab tshuaj npaj yam tsis hloov cov khoom tiav.
