Izakhiwo kanye nokusetshenziswa kwe-lanolin

I-Lanoliniwumkhiqizo othathwe ngemuva kokugezwa koboya obuqinile, okhishwa futhi ucutshungulwe ukuze kukhiqizwe i-lanolin ecwengekile, eyaziwa nangokuthi i-sheep wax. Ayinawo ama-triglyceride futhi iwumkhiqizo ovela ezinhlamvini zesikhumba semvu.
I-Lanolin ifana ngokwakheka kwe-sebum yomuntu futhi isetshenziswe kabanzi emikhiqizweni yezimonyo kanye nemithi yokwelapha. I-Lanolin iyahluzwa futhi izinhlobo ezahlukene ze-lanolin zikhiqizwa ngezinqubo ezahlukene ezifana nokuhlukaniswa, i-saponification, i-acetylation kanye ne-ethoxylation. Okulandelayo isingeniso esifushane sezakhiwo kanye nokusetshenziswa kwe-lanolin.
I-lanolin engenamanzi
Umthombo:Into emsulwa efana ne-wax etholakala ngokugeza, ukususa umbala kanye nokususa iphunga kuboya bezimvu. Okuqukethwe kwamanzi e-lanolin akudluli ku-0.25% (ingxenye yesisindo), kanti inani le-antioxidant lifinyelela ku-0.02% (ingxenye yesisindo); I-EU Pharmacopoeia 2002 icacisa ukuthi i-butylhydroxytoluene (BHT) engaphansi kuka-200mg/kg ingafakwa njenge-antioxidant.
Izakhiwo:I-lanolin engenamanzi iyinto ephuzi kancane, enamafutha, efana ne-wax enephunga elincane. I-lanolin encibilikisiwe iwuketshezi oluphuzi olubonakalayo noma olucishe lubonakale. Incibilika kalula ku-benzene, i-chloroform, i-ether, njll. Ayincibiliki emanzini. Uma ixutshwe namanzi, ingamunca amanzi kancane kancane alingana nesisindo sayo izikhathi ezimbili ngaphandle kokuhlukana.
Izicelo:I-Lanolin isetshenziswa kabanzi ekulungiseleleni imithi kanye nezimonyo. I-Lanolin ingasetshenziswa njengesithwali esingathandi amanzi ekulungiseleleni ukhilimu namafutha afakwe emanzini. Uma ixutshwe namafutha emifino afanele noma i-petroleum jelly, ikhiqiza umphumela wokuthambisa futhi ingene esikhumbeni, ngaleyo ndlela ilula ukumuncwa kwemithi.I-Lanolinixutshwe cishe nenani lamanzi eliphindwe kabili ayihlukani, futhi i-emulsion ephumayo cishe ayinawo amathuba amaningi okuthi ivuvuke lapho igcinwa.
Umphumela wokuhlanganisa we-lanolin ubangelwa kakhulu amandla amakhulu okuhlanganisa ama-α- kanye nama-β-diols aqukethe, kanye nomphumela wokuhlanganisa ama-cholesterol esters kanye nama-alcohols aphezulu. I-Lanolin igcoba futhi ithambise isikhumba, ikhulisa okuqukethwe kwamanzi ebusweni besikhumba, futhi isebenza njenge-ejenti yokumanzisa ngokuvimbela ukulahleka kokudluliselwa kwamanzi e-epidermal.
Ngokungafani nama-hydrocarbon angewona ama-polar njengamafutha amaminerali kanye ne-petroleum jelly, i-lanolin ayinakho ukukhiqiza i-emulsifying futhi ayimuncwa yi-stratum corneum, ithembele kakhulu emphumeleni wokumuncwa kwe-emolliency kanye nokumuncwa. Isetshenziswa kakhulu kuzo zonke izinhlobo zokhilimu bokunakekelwa kwesikhumba, amafutha okwelapha, imikhiqizo ye-sunscreen kanye nemikhiqizo yokunakekelwa kwezinwele, futhi isetshenziswa nasezimonyweni zobuhle ze-lipstick kanye nensipho, njll.
Ukuphepha:Ithambile kakhului-lanolinkuphephile futhi kuvame ukubhekwa njengento engenabo ubuthi futhi engacasuli, futhi amathuba okungezwani ne-lanolin kubantu alinganiselwa ku-5%.
