Cosmetic preservatives yog ib qho tseem ceeb ntawm cov formulations, siv los inhibit microbial kev loj hlob thiab kev yug me nyuam, tiv thaiv cov khoom spoilage, thiab xyuas kom meej cov khoom muaj kev ruaj ntseg. Daim ntawv ntau npaum ntawm cov tshuaj pleev ib ce muaj qhov sib txawv ntawm cov kev cai khaws cia: cov khoom uas muaj cov ntsiab lus dej ntau dua (xws li toners thiab lotions) yuav tsum muaj cov tshuaj tua kab mob ntau dua; thaum cov tshuaj pleev ib ce ze rau cov roj los yog cov quav ciab, vim lawv cov dej tsis ua haujlwm, muaj qhov cuam tshuam rau kev loj hlob ntawm cov kab mob microbial thiab yog li xav tau cov tshuaj tua kab mob tsawg dua.
Hauv kev tsim cov tshuaj pleev ib ce, ntau cov tshuaj tua kab mob feem ntau ua ke kom nthuav dav cov kab mob tua kab mob, txhim kho kev ua kom zoo dua qub, thiab tiv thaiv kev kis kab mob thib ob. Kev ua tiav "preservative-}dawb" cov khoom lag luam feem ntau suav nrog ob txoj hauv kev: ib qho yog ntxiv cov tshuaj tua kab mob ntau dua li tau tso cai rau kev siv tshuaj pleev ib ce; lwm qhov yog ua raws li kev khaws cia- cov qauv khoom pub dawb nyob rau hauv cov nqe lus ntawm kev tsim cov tshuaj ntau npaum li cas (xws li cov qauv roj ntshiab, cov qauv tsim khoom) thiab cov ntawv ntim khoom (xws li lub tshuab nqus tsev ntim, ib zaug - siv ntim).
Noj Bloomage Biotechnology ua piv txwv, nws txo lossis hloov kev siv cov tshuaj tiv thaiv ib txwm siv los ntawm kev siv dav dav uas suav nrog cov khoom siv raw (xws li siv cov tshuaj tua kab mob ntawm polyols), aseptic filling technology, thiab lub tshuab nqus tsev xovxwm ntim. Cov tshuaj pleev ib ce uas yog "preservative-dawb" nyob rau hauv kev ua lag luam feem ntau poob rau hauv peb pawg: cov khoom uas tiag tiag tsis muaj preservatives (xws li cov tshuaj ntsiav pov tseg thiab cov roj yam tseem ceeb); cov khoom uas muaj cov khoom xyaw nrog preservative yam tab sis tsis tau teev nyob rau hauv daim ntawv tso cai siv (xws li pentylene glycol thiab caprylyl glycol); thiab cov khoom uas xav tias yog kev tshaj tawm cuav lossis kev dag ntxias cov neeg siv khoom.
