Imfihlo Yokunakekelwa Kwesikhumba Yemvelo: I-Lanolin Anhydrous

Iyini i-lanolin? I-Lanolin iwumkhiqizo otholwe ekugezweni komshini wokuhlanza uvolo omahhadla, okhishwa bese ucutshungulwa ukuze kukhiqizwe i-lanolin ecwengiwe, eyaziwa nangokuthi i-wax yezimvu. Inamathiselwe eboyeni bokukhishwa kwamafutha, ukucwengwa kanye nokucwengisiswa kwamafutha aphuzi noma ansundu-ophuzi, umuzwa we-viscous kanye nokushelela, izingxenye eziyinhloko ama-sterols, ama-alcohols anamafutha kanye notshwala be-triterpene kanye nenani elifanayo lamafutha acid akhiqizwa i-ester, kanye nenani elincane lamafutha amahhala nama-hydrocarbons.

Ngokufanayo ekubunjweni kwayo ku-sebum yomuntu, i-lanolin kanye nokuphuma kwayo kusetshenziswe kabanzi kuzimonyo nasemikhiqizweni yezidakamizwa ze-topical. I-Lanolin ingenziwa ibe yi-lanolin ecolisisiwe kanye nokuphuma kwe-lanolin okuhlukahlukene ngokusebenzisa izinqubo ezihlukahlukene ezifana nokuhlukaniswa, i-saponification, i-acetylation kanye ne-ethoxylation.

I-Anhydrous lanolin iwuketshezi lwengcina oluhlanzekile olutholakala ngokuwasha, ukubola nokukhipha amaphunga uboya bezimvu. Okuqukethwe kwamanzi e-lanolin akukho ngaphezu kwe-0.25% (ingxenye enkulu), futhi inani le-antioxidant lingaba ngu-0.02% (ingxenye enkulu); i-European Union Pharmacopoeia 2002 icacisa ukuthi i-butylated hydroxytoluene (BHT), engaphansi kuka-200mg/kg, ingengezwa njenge-antioxidant. I-anhydrous lanolin into ephuzi ngokukhanyayo, enamafutha efana nengcina enephunga elincane. I-lanolin encibilikisiwe ibonakalisa ngale noma icishe ibe sobala uketshezi oluphuzi. Incibilika kalula ku-benzene, i-chloroform, i-ether, njll., ayincibiliki emanzini, uma ixutshwe namanzi, kancane kancane ingamunca amanzi alingana nesisindo esiphindwe izikhathi ezi-2 ngaphandle kokuhlukana.

I-Lanolin isetshenziswa kabanzi ekulungiseleleni izidakamizwa ezisezingeni eliphezulu nezimonyo. I-Lanolin ingasetshenziswa njengesithwali se-hydrophobic ekulungiseleleni ama-creams namafutha okugcoba emanzini. Uma ixubene namafutha emifino afanelekile noma i-petroleum jelly, ikhiqiza umphumela we-emollient futhi ingena esikhumbeni, ngaleyo ndlela ikhuthaze ukumuncwa kwezidakamizwa. I-Lanolin ayihlukani nenani lamanzi eliphindwe kabili futhi i-emulsion ewumphumela ayingenwa kalula yi-rancidity ngesikhathi sokugcinwa.

Umthelela we-emulsifying we-lanolin ngokuyinhloko ungenxa yekhono eliqinile lokuhlanganisa i-α- kanye ne-β-diols equkethe, ngaphezu kwe-cholesterol esters kanye notshwala obuphezulu obunomthelela emulsifying effect. I-Lanolin igcoba futhi ithambisa isikhumba, ikhuphule okuqukethwe kwamanzi angaphezulu kwesikhumba, futhi isebenza njenge-moisturizer ngokuvimbela ukulahlekelwa ukudluliswa kwamanzi e-epidermal.

I-Lanolin kanye ne-non-polar hydrocarbons, njengamafutha amaminerali kanye ne-petroleum jelly ihlukile, ama-emollients e-hydrocarbon ngaphandle kwekhono emulsifying, cishe awamuncwa yi-stratum corneum, ngokuqinile ngokumuncwa nokugcina umphumela we-emolliency kanye nokuswakama. Ikakhulukazi isetshenziswa kuzo zonke izinhlobo zokhilimu bokunakekelwa kwesikhumba, amafutha okugcoba, imikhiqizo yokuvikela ilanga kanye nemikhiqizo yokunakekelwa kwezinwele, esetshenziswa nasezintweni zokugcoba umlomo nensipho.

I-Ultra refined lanolin iphephile futhi ngokuvamile ibhekwa njengento engenabuthi nengacasuli. Amathuba okungezwani ne-lanolin kubantu alinganiselwa ku-5%.

I-Lanolin nayo inomphumela wokuthambisa esikhumbeni. Isondla ngobumnene ubuso besikhumba, ilinganise ukukhiqizwa kukawoyela, futhi ithuthukise ukunwebeka nokukhazimula kwesikhumba.

I-Lanolin nayo inezindawo ezithile zokubuyisela esimweni. Lapho isikhumba sethu sishukunyiswa noma sonakaliswa imvelo yangaphandle, i-lanolin ingakhuthaza ukuvuselelwa nokulungiswa kwamangqamuzana esikhumba futhi isheshise ukubuyiswa kwezindawo ezilimele. Ngakho-ke, kwabanye abantu abanezinkinga ezincane zesikhumba, njengesikhumba esomile, ubomvu, ukukhishwa, njll, ukusetshenziswa kwemikhiqizo yokunakekelwa kwesikhumba equkethe i-lanolin ingadlala indima ethile ekudambiseni nasekulungiseni.

I-Lanolin nayo inomphumela othile we-antioxidant. Icebile ngamavithamini kanye nama-antioxidants anganciphisa ama-radicals mahhala futhi abambezele inqubo yokuguga kwesikhumba.

Njengesithako esivamile sokuthambisa semvelo, i-lanolin inemiphumela ehlukahlukene kanye nemisebenzi emikhiqizweni yokunakekelwa kwesikhumba. Ithambisa kahle futhi inondle, ithambisa isikhumba, ilungise izindawo ezilimele futhi ilwe ne-oxidation. Uma ufuna ukuba nesikhumba esimanzi, esinomsoco, esithambile futhi esibushelelezi, khetha umkhiqizo we-skincare oqukethe i-lanolin. Ukusetshenziswa isikhathi eside kwemikhiqizo ye-skincare equkethe izithako ze-lanolin kungenza isikhumba sakho sibe sisha futhi siqine, futhi kuvimbele ukukhula kwemigqa emihle nemibimbi.
