Phakathi kuka-80 vs Phakathi kuka-20: Umehluko Oyinhloko kanye nokuthi Ungakhetha Kanjani Isicelo sakho

Phakathi kuka-20 no-Tween 80 womabiliI-I-Polyoxyethylene Sorbitan Fatty Acid Esters (TWEEN), ama-surfactants angama-nonionic asetshenziswa kakhulu ekunakekelweni komuntu siqu, kwezemithi, ekusetshenzisweni kokudla nasezimbonini. Aphinde abizwe ngokuthi yi-TW20 kanye ne-TW80 kwezinye izimboni. Ngenxa yokuthi amagama afanayo, abathengi abaningi babuza umbuzo ofanayo: uyini umehluko phakathi kwe-Tween 20 kanye ne-Tween 80, futhi ingabe ingasetshenziswa ngokushintshana?

Empeleni, i-Tween 20 kanye ne-Tween 80 ivamise ukukhethwa kumasistimu okwakhiwa ahlukene. Umehluko omkhulu uvela ku-fatty acid base. I-Tween 20 (i-Polysorbate 20) isuselwa ku-lauric acid enenani le-HLB elingu-16.7, kuyilapho i-Tween 80 (i-Polysorbate 80) isuselwa ku-oleic acid enenani le-HLB elingu-15.0. Nakuba zombili zingama-surfactants e-nonionic ancibilikayo emanzini, lo mehluko wesakhiwo uthinta ukuziphatha kwawo kwe-emulsification, ukuhambisana kukawoyela nokuzinza kokwakheka.

Phakathi kwama-20: Okungcono Ezinhlelweni Zokuqiniswa Kwamanzi Nezithambile

Inani eliphakeme le-HLB le-Tween 20 liyenza ibe ne-hydrophilic kakhulu, yingakho ivame ukukhethwa kumasistimu adinga ukuhlakazeka kwamanzi okuhle kanye ne-emulsification encane. Izinhlelo zokusebenza ezijwayelekile zifaka:

• Imikhiqizo yokunakekelwa komuntu siqu njengezihlanzi zobuso, amathoni namanzi e-micellar, lapho kudingeka khona ukuncibilikiswa okuthambile kwephunga elimnandi noma izithako zikawoyela.
• Ukwakhiwa kwezimonyo ezidinga ama-emulsifiers angacasuka kancane
• Amalungiselelo emithi ahlanganisa izixazululo zomlomo kanye nokwakheka kwezihloko
• Izicelo zaselabhorethri ezifana ne-protein solubilization kanye nemidiya yesiko lamaseli

I-Tween 80: Ingcono kuma-Oil-Containing and Emulsion Systems

Inani eliphansi kancane le-HLB nesisekelo se-oleic acid se-Tween 80 siyenza ifaneleke kakhulu kumasistimu anokuqukethwe uwoyela okuphezulu, noma lapho izithako ezisebenzayo ezincibilika uwoyela zidinga ukuhlakazwa noma ukuncibilika. Isetshenziswa kabanzi ku:

• Ama-emulsions e-cosmetic afana nama-creams nama-lotions lapho i-emulsification yamafutha emanzini eqinile iyadingeka.
• Imikhiqizo yemithi ehlanganisa ukwakheka komjovo, ama-emulsions omlomo kanye nokuhlakazeka kwamafutha kavithamini
• Imikhiqizo yokudla okunempilo efana ne-fat-soluble vitamin emulsification eziphuzweni nasezithasiselweni
• Izicelo zezimboni ezihlanganisa i-lubricant emulsification kanye nezinsiza zendwangu

Ungakhetha Kanjani Phakathi Kwama-20 Naphakathi Kwama-80

Ukukhetha akufanele kusekelwe egameni lomkhiqizo kuphela. Izici ezibalulekile okufanele zicatshangelwe zihlanganisa izidingo ze-HLB, uhlobo lwesigaba sikawoyela nokugxilwa kwayo, ukuhambisana nezinye izinto ezisetshenziswayo noma izithako ezisebenzayo, izidingo zekhwalithi nemibhalo, kanye nokuzinza komkhiqizo ngaphansi kokushisa, i-pH nezimo zokugcinwa.

Njengoba amakhasimende amaningi eqhathanisa lawa mabanga amabili ngesikhathi sokukhethwa komkhiqizo, i-Dotachem ilungiselele ithebula lokuqhathanisa elilula ukuze lisetshenziswe.

Ezimweni eziningi, ukuhlolwa kwezinga elincane kuyanconywa ngaphambi kokuqinisekisa ibanga lokugcina, njengoba ukusebenza kungahluka kuye ngezimo zangempela zohlelo.

Emaqenjini okuthenga, kubalulekile futhi ukuqinisekisa ukucaciswa komkhiqizo, izinketho zokupakisha, isikhathi sokuhola kanye namadokhumenti obuchwepheshe adingekayo ngaphambi kokufaka i-oda. Lokhu kubaluleke kakhulu kumakhasimende ekunakekelweni komuntu siqu, ukwenza imithi kanye nokukhiqiza okugxile ekuthumeleni kwamanye amazwe.

I-Dotachem ingumphakeli osekelwe e-China wemikhiqizo ye-Polysorbate ehlanganisa i-Tween 20 (Polysorbate 20) ne-Tween 80 (i-Polysorbate 80) yokunakekelwa komuntu siqu, izicelo zemithi nezezimboni. Amakhasimende angase abe nentshisekelo emikhiqizweni ehlobene efana neI-I-Sorbitan Monolaurate(Spani),I-I-Polyethylene Glycol(I-PEG),Ipropylene Glycol(PG) namanye ama-surfactants akhethekile.

Oxhumana nayeI-Dotachem yokucaciswa komkhiqizo, izinketho zokupakisha noma ukusekelwa kwekhotheshini kwabasebenza ngochungechunge lwe-Tween.
