Sodium ethylparaben yog cov dej tshaj lij -cov tshuaj tiv thaiv zoo rau cov kua mis dej. Nws muaj cov dej solubility zoo heev, muaj peev xwm yaj sai sai hauv chav tsev -cov dej huv huv thiab ua kom pom kev sib raug zoo nrog cov kuab tshuaj organic xws li ethanol. Lub caij no, cov khoom no yog insoluble kiag li nyob rau hauv non-polar tshuaj xws li ntxhia roj, roj thiab diethyl ether. Nyob rau hauv tus txheej txheem ntawm chav tsev kub thiab atmospheric siab, cov khoom siv raw khoom ruaj khov tshuaj tsis muaj deterioration. Nws khaws cov tshuaj tua kab mob ruaj khov thiab ua tau zoo heev - kub tsis kam nyob rau hauv nruab nrab thiab tsis muaj zog alkaline aqueous systems, siab yoog raws li cov txheej txheem cua sov rau txhua hnub tshuaj thiab khoom noj khoom haus. Txawm li cas los xij, ib puag ncig acidic muaj zog yuav ua rau nag lossis daus ntawm ethylparaben, uas ua rau tsis muaj kev tiv thaiv zoo thiab tsis ua haujlwm ntawm cov tshuaj tiv thaiv kab mob.
Qhov Zoo Tshaj Plaws
Cov khoom no muaj lub zog dav dav -spectrum bacteriostatic thiab antifungal muaj peev xwm, zoo inhibiting cov kab mob hauv dej, pwm thiab cov poov xab.
Nws ruaj khov thiab ntev -kev ua tau zoo khaws cia ntev tshaj qhov ua tau zoo tshaj plaws ntawm cov dej zoo tib yam-raws li preservatives, txhim khu kev ruaj ntseg microbial stability ntawm cov khoom tiav thoob plaws hauv lub txee lub neej.
Tshem tawm qhov xav tau kev pab solubilization zoo li ethanol thiab propylene glycol, cov khoom xyaw tuaj yeem yaj tag nrho hauv chav -kub dej ntshiab, ua kom yooj yim cov txheej txheem tsim khoom thiab zam cov khoom muaj peev xwm ua rau khaus thiab muaj kev pheej hmoo los ntawm cov organic solvents.
Tshem tawm qhov xav tau kev pab solubilization zoo li ethanol thiab propylene glycol, cov khoom xyaw tuaj yeem yaj tag nrho hauv chav -kub dej ntshiab, ua kom yooj yim cov txheej txheem tsim khoom thiab zam cov khoom muaj peev xwm ua rau khaus thiab muaj kev pheej hmoo los ntawm cov organic solvents.
Tsis tas li ntawd, qhov siab -purity raw khoom ua raws li lub teb chaws cov qauv rau tshuaj pleev ib ce, zaub mov additives thiab tshuaj excipients, xa me me kev ntxhib los mos thiab zoo heev kev nyab xeeb nyob rau hauv tus qauv ntau npaum li cas.

Daim ntawv thov
Raws li ntau yam dav dav -spectrum dej-soluble preservative, sodium ethylparaben yog siv dav hauv tshuaj zoo, kev saib xyuas tus kheej, kev ua zaub mov thiab kev lag luam tshuaj. Hauv cov tshuaj pleev ib ce thiab kev saib xyuas tus kheej, nws yog qhov tsim nyog rau ntau hom yaug - tawm thiab tawm - ntawm cov khoom lag luam aqueous, suav nrog cov tshuaj pleev tawv nqaij, cov kua tshuaj zawv plaub hau, tshuaj zawv plaub hau, tshuaj ntxuav lub cev, tshuaj txhuam hniav thiab dej- raws li lub ntsej muag lub ntsej muag, ua tau raws li kev cai tswj hwm kev zoo nkauj hauv tsev. Hauv kev lag luam khoom noj khoom haus, nws ua haujlwm zoo li tshuaj tua kab mob rau cov kua txiv hmab txiv ntoo, dej qab zib carbonated, seasoning sauces thiab prefabricated kua zaub mov, txwv tsis pub microbial kev loj hlob thiab txuas ntxiv cov khoom txee lub neej raws li kev soj ntsuam zaub mov hauv tebchaws. Nws kuj ua raws li cov khoom siv tshuaj tua kab mob tseem ceeb rau cov tshuaj kho mob sab nraud, kev npaj kho tawv nqaij thiab dej-raws li cov khoom siv tu, ua tau raws li cov kws tshaj lij kws tshuaj- cov qauv tsim qib.
Ntim & Cia
Cov txheej txheem ntim khoom tshwj xeeb yog 25kg ib daim ntawv nruas nruab nrog ob npaug - txheej zaub mov - qib ya raws- cov hnab yas hauv cov pov thawj kom ntseeg tau tias kev ua tau zoo sealing zoo, thiab cov txheej txheem ntim khoom muaj raws li cov neeg siv khoom xav tau.
Rau kev tswj kev cia khoom, cov khoom yuav tsum tau khaws cia hauv qhov txias, qhuav, huv si thiab zoo -ventilated warehouses. Lub teeb ci ncaj qha thiab siab - qhov kub thiab txias ib puag ncig raug txwv nruj, thiab sib xyaw cia nrog cov kua qaub muaj zog, muaj zog alkali thiab oxidizing tshuaj raw khoom yog txwv tsis pub. Vim nws cov khoom muaj zog nqus dej noo, cov khoom yuav tsum tau ntim puv thaum lub sij hawm cia kom tiv thaiv kom tsis txhob ya raws thiab tsis zoo.
