Lanolin (Lanolin, E913) - glazier. Wool wax, tsiaj wax tau los ntawm ntxuav cov ntaub ntawm yaj.
Lub viscous brownish-daj loj. Nws txawv ntawm lwm cov waxes nrog cov ntsiab lus siab ntawm sterols (tshwj xeeb, cov roj cholesterol). Lanolin tau zoo absorbed rau hauv daim tawv nqaij thiab muaj ib tug softening nyhuv. Qhov no yog tuab, ntom ntom ntawm cov xim daj lossis xim daj-xim av, tsw ntxhiab tsw, yaj ntawm qhov kub ntawm 36-42 ° C.
Qhov sib xyaw ntawm lanolin yog qhov nyuaj heev thiab tseem tsis tau kawm tag nrho. Yeej, nws yog ib qho kev sib xyaw ntawm esters ntawm high-molecular alcohols (cholesterol, isocholesterol, thiab lwm yam) nrog cov fatty acids ntau dua (myristic, palmitic, cerotinic, thiab lwm yam) thiab dawb-molecular alcohols. Raws li cov khoom ntawm lanolin, nws yog ze rau tib neeg sebum.
Nyob rau hauv cov ntsiab lus tshuaj, nws yog heev inert, nruab nrab thiab ruaj khov thaum lub sij hawm cia. Cov cuab yeej tseem ceeb tshaj plaws ntawm lanolin yog nws lub peev xwm los ua emulsify txog 180-200% (ntawm nws tus kheej qhov hnyav) dej, mus txog 140% glycerol thiab txog 40% ethanol (70% concentration) los tsim dej / roj emulsions. Qhov sib ntxiv ntawm ib qho me me ntawm lanolin rau cov rog thiab hydrocarbons ua rau lawv muaj peev xwm sib tov nrog dej thiab aqueous daws, uas ua rau nws siv dav hauv cov tshuaj lipophilic-hydrophilic hauv paus.
Nws yog dav siv los ua ib feem ntawm ntau yam tshuaj pleev ib ce-cream, thiab lwm yam, nyob rau hauv cov tshuaj nws yog siv los ua ib lub hauv paus rau ntau yam tshuaj pleev, nrog rau softening ntawm daim tawv nqaij (sib tov nrog ib tug sib npaug zos npaum li cas ntawm vaseline).
Ntshiab, huv si lanolin muaj rau cov poj niam laus (lub npe lag luam: Purelan, Lansinoh). Siv cov tshuaj pleev ib ce, lanolin pab kho cov kab nrib pleb ntawm lub txiv mis thiab tiv thaiv lawv cov tsos, thiab tsis tas yuav yaug dej ua ntej pub mis (tsis muaj kev phom sij rau cov menyuam mos).
