Tween-80
Kev siv hauv cov khoom siv mis nyuj
Feem ntau siv hauv cov dej haus muaj protein ntau yog Tween 60 (14.9 HLB) thiab Tween 80 (15.0 HLB).Vim tias nws tus nqi HLB siab thiab nws tus nqi qis dua li ntawm sucrose ester thiab lwm yam emulsifiers nrog tus nqi sib npaug HLB, feem ntau yog siv ua ke nrog qis HLB tus nqi monoglycerol, lauj kaub, sucrose ester thiab lwm yam kom tau raws li qhov xav tau ntawm ntau yam protein. dej haus.Feem ntau siv emulsifiers hauv cov kua zaub protein mis haus yog sucrose ester, monoglycyl ester, lauj kaub, ttwain thiab lecithin.Feem ntau siv ua ke nrog ob lossis ntau dua emulsifiers, uas ua rau cov txiaj ntsig zoo dua thaum siv ib leeg.Tus nqi ntawm emulsifier ntxiv yog feem ntau txog 12% ntawm cov roj.
Stability thiab cia tej yam kev mob:
Twain hom surfactants yog qhov ruaj khov, ruaj khov rau electrolyte, tsis muaj zog acid thiab tsis muaj zog puag;Muaj zog acid thiab lub hauv paus yuav maj mam saponify;Nws oleate yog yooj yim rau oxidize, cia lub sij hawm ntev dhau lawm yuav tsim peroxide.Peroxide, hnyav hlau ions, kub nce, lub teeb irradiation, dej tov autoxidation yog ceev, polyoxyethylene saw tawg, tib lub sij hawm hydrolysis rau fatty acids.Cov tshuaj aqueous ntawm Tween 80 yog qhov ruaj khov ntawm pH 3 ~ 7.6, thiab tus nqi hydrolysis yog qhov qis tshaj.Twain yuav tsum tau muab cia rau hauv ib lub thawv airtight hauv qhov chaw txias thiab qhuav kom deb ntawm lub teeb.

Cov khoom:
Txij li Twain yog ib qho ester tsim los ntawm sorbitol thiab cov roj fatty acids sib txawv, Twain yog cov khoom lag luam ntawm tib hom, uas tau muab faib ua 20,40,60,80 hom hauv khw muag tshuaj zoo lossis cov tuam txhab tshuaj reagent, thiab yog xaiv raws li kev xav tau sib txawv.
Tween 20 (TWEEN-20) Twain 21 (TWEEN-21) Twain 40 (TWEEN-40) Twain 60 (TWEEN-60) Twain 61 (TWEEN-61) Twain 80 (TWEEN-80) Twain 81 (TWEEN-81) 85 (TWS-85);
Tween-60 yog stearate;Tween-80 yog oleate;Tween-20 yog laurate, sib tov ntawm polyoxyethylene sorbitan monolaurate thiab ib feem ntawm polyoxyethylene ob chav sorbitan monolaurate.
