Izakhiwo kanye nokusetshenziswa kwe-lanolin

I-Lanoliniwumkhiqizo otholakala ekugezweni koboya obumahhadla, obukhishwa futhi bucutshungulwe ukuze bukhiqize i-lanolin ecwengiwe, eyaziwa nangokuthi i-wax yezimvu.Ayiqukethe noma yimaphi ama-triglycerides futhi iwukuphuma kwezindlala ze-sebaceous zesikhumba semvu.
I-Lanolin iyafana ngokwakhiwa kwe-sebum yomuntu futhi isetshenziswe kakhulu emikhiqizweni yezidakamizwa zezimonyo nezangaphakathi.I-Lanolin iyacwengwa futhi okuphuma ku-lanolin okuhlukahlukene kukhiqizwa ngezinqubo ezahlukahlukene njengokuhlukaniswa, i-saponification, i-acetylation kanye ne-ethoxylation.Okulandelayo isingeniso esifushane sezakhiwo kanye nokusetshenziswa kwe-lanolin.
I-lanolin engenamanzi
Umthombo:Ingxube yengcina emsulwa etholwe ngokuwasha, ukukhipha umbala nokunukisa uboya bezimvu.Okuqukethwe kwamanzi kwe-lanolin akukho ngaphezu kwe-0.25% (ingxenyana yobuningi), futhi inani le-antioxidant lifika ku-0.02% (ingxenyana yobuningi);I-EU Pharmacopoeia 2002 icacisa ukuthi i-butylhydroxytoluene (BHT) engaphansi kuka-200mg/kg ingangezwa njenge-antioxidant.
Izakhiwo:I-anhydrous lanolin into ephuzi ngokukhanyayo, enamafutha, enengcina enephunga elincane.I-lanolin encibilikisiwe iwuketshezi oluphuzi olusobala noma olucishe lube sobala.Incibilika kalula ku-benzene, i-chloroform, i-ether, njll. Ayincibiliki emanzini.Uma ixutshwe namanzi, kancane kancane ingakwazi ukumunca amanzi alingana nezikhathi ezi-2 zesisindo sayo ngaphandle kokuhlukana.
Izicelo:I-Lanolin isetshenziswa kabanzi emalungiselelweni emithi asematheni nasezimonyoni.I-Lanolin ingasetshenziswa njengesithwali se-hydrophobic sokulungiswa kwamanzi okhilimu namafutha okugcoba.Uma ixubene namafutha emifino afanelekile noma i-petroleum jelly, ikhiqiza umphumela we-emollient futhi ingena esikhumbeni, ngaleyo ndlela kube lula ukumuncwa kwezidakamizwa.I-Lanolinexutshwe cishe kabili inani lamanzi alihlukani, futhi i-emulsion ewumphumela mancane amathuba okuba i-rancidify endaweni yokugcina.
Umphumela we-emulsifying we-lanolin ngokuyinhloko ubangelwa amandla aqinile e-emulsifying we-α- kanye ne-β-diols ewaqukethe, kanye nomphumela we-emulsifying we-cholesterol esters kanye notshwala obuphezulu.I-Lanolin ithambisa futhi ithambisa isikhumba, ikhuphule okuqukethwe kwamanzi endaweni yesikhumba, futhi isebenza njenge-ejenti yokumanzisa ngokuvimbela ukulahlekelwa ukudluliswa kwamanzi e-epidermal.
Ngokungafani nama-hydrocarbon angewona ama-polar afana nowoyela wamaminerali kanye ne-petroleum jelly, i-lanolin ayinalo ikhono lokufaka emulsifying futhi ayimuncwe neze i-stratum corneum, incike eduze emphumeleni wokumunca we-emollientation kanye nokuswakama.Isetshenziswa kakhulu kuzo zonke izinhlobo zokhilimu bokunakekelwa kwesikhumba, amafutha okugcoba, imikhiqizo yokuvikela ilanga kanye nemikhiqizo yokunakekelwa kwezinwele, futhi isetshenziselwa izimonyo zobuhle be-lipstick nensipho, njll.
Ukuphepha:Ithambile kakhului-lanoliniphephile futhi ngokuvamile ibhekwa njengento engenabuthi nengacasuli, futhi amathuba okuba ne-lanolin allergy kubantu alinganiselwa ku-5%.
