Raws li qib siab -kev ua tau zoo khaws cia hauv tsev neeg paraben sodium, sodium propylparaben muaj cov kuab tshuaj sib txawv ntawm chav tsev kub. Soluble hauv dej, glycerol thiab propylene glycol, cov khoom muaj ethanol solubility zoo dua li sodium methylparaben thiab sodium ethylparaben, tab sis nws cov dej solubility yog marginally qis dua sodium ethylparaben, thiab nws tsis tuaj yeem yaj hauv oily media. Cov khoom siv raw tseem nyob hauv cov tshuaj inert thaum khaws cia rau hauv qhuav thiab ntxoov ntxoo. Nws cov qauv aqueous nyob ruaj khov hla tsis muaj zog acidic rau nruab nrab pH ib puag ncig (pH 3-7). Thaum raug cov kua qaub muaj zog, hydrolysis tshwm sim thiab tsim cov propylparaben precipitate insoluble, ua rau tsis ua haujlwm ntawm cov kab mob. Muab kaw kom raug thiab khaws cia rau hauv qhov chaw txias, qhuav thiab qhov cua, cov khoom tuaj yeem tsim nyog thiab siv tau rau 24 lub hlis.
Qhov Zoo Tshaj Plaws
Sodium propylparaben yog ntau yam dav -spectrum antimicrobial tus neeg sawv cev, tshwj xeeb tshaj yog muaj zog hauv kev tshem tawm cov pwm thiab cov kab mob poov xab.
Los ntawm kev rhuav tshem cov kab mob microbial membrane thiab inhibiting kev ua haujlwm hauv enzymatic, nws zoo suppresses microbial proliferation.
Ntawm tag nrho cov paraben preservatives, ntev carbon chains coj muaj zog antibacterial muaj peev xwm, yog li sodium propylparaben nyob rau saum toj nyob rau hauv bacteriostatic nyhuv ntawm methyl, ethyl thiab propyl paraben sodium ntsev.
Tsis tas li ntawd, nws cov roj optimized- cov khoom faib dej ua kom zoo dua Gram - cov kab mob tsis zoo inhibition muaj peev xwm.
Nrog rau cov tshuaj ruaj khov ua tau zoo thiab kev sib raug zoo ntawm cov mis, nws yog ib qho kev nyab xeeb thiab txhim khu kev ruaj ntseg xaiv rau emulsified cov tshuaj txhua hnub thiab kev npaj kho mob.

Daim ntawv thov
Npog kev saib xyuas tus kheej thiab kev lag luam tshuaj, sodium propylparaben yog ntau -scenario preservative khoom. Nws yog feem ntau ntxiv rau cov khoom siv tshuaj pleev ib ce niaj hnub nrog rau cov tshuaj pleev tawv nqaij, tshuaj pleev lub cev thiab tshuaj zawv plaub hau kom ruaj khov cov khoom zoo thiab ua kom lub neej ntev. Meanwhile, nws yog dav saws nyob rau hauv kev tsim tshuaj, muaj feem xyuam rau ntau yam kua tshuaj cov khoom thiab lwm yam tawv nqaij npaj, muab ruaj khov thiab raws li antibacterial preservation rau kev kho mob pab formulations.
Ntim & Cia
Kev lag luam ntim ntim tau txais 25kg lined ntawv nruas nrog ob npaug khoom noj- qib hnab yas sab hauv, thiab kev ntim khoom yooj yim tau txais kev txhawb nqa rau kev txiav txim ntau.
Txhawm rau tswj cov khoom lag luam ruaj khov, khaws cov khoom muag hauv qhov chaw qhuav, ntxoov ntxoo thiab ventilated sab hauv tsev. Khaws kom deb ntawm qhov chaw sov thiab tshav ntuj, thiab cais tawm ntawm cov khoom siv tshuaj acidic thiab alkaline txhua lub sijhawm. Tight sealing thaum lub sij hawm cia yog qhov tseem ceeb los tiv thaiv kev ya raws thiab cov khoom agglomeration.
Quality & Service
Tsim nyob rau hauv ISO-cov chaw muaj ntawv pov thawj, txhua pawg tuaj nrog Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (COA). Peb muab cov khoom siv txhim khu kev qha, kev txhawb nqa, thiab kev sib tw nqi rau kev txiav txim ntau.
