Imfihlo yoKhathalelo lweNdalo yolusu: iLanolin Anhydrous

Yintoni lanolin? I-Lanolin yimveliso efunyenwe ekuhlanjweni kwesicoci soboya esirhabaxa, esitsalwa kwaye silungiswe ukuvelisa i-lanolin esulungekisiweyo, nekwaziwa ngokuba yi-wax yeegusha. Incanyathiselwe kuboya bemfihlo yegrisi, ukucocwa kunye nokusulungekiswa kwe-ointment etyheli okanye emdaka-mthubi, imvakalelo ebonayo kunye nemtyibilizi, ezona nxalenye ziphambili zi-sterols, i-alcohols ezinamafutha kunye nee-alcohols ze-triterpene kunye malunga nesixa esifanayo se-acids enamafutha aveliswa i-ester, kunye nenani elincinci leeasidi ezinamafutha asimahla kunye neehydrocarbons.

Ngokufanayo ekubunjweni kwe-sebum yabantu, i-lanolin kunye ne-derivatives yayo isetyenziswe ngokubanzi kwiimveliso zokuthambisa kunye neemveliso zamachiza. I-Lanolin inokwenziwa kwi-lanolin ephuculweyo kunye neentlobo ezahlukeneyo ze-lanolin ngokusebenzisa iinkqubo ezahlukeneyo ezifana ne-fractionation, i-saponification, i-acetylation kunye ne-ethoxylation.

I-Anhydrous lanolin yinto esulungekileyo ene-waxy efunyenwe ngokuhlanjwa, ukuhombisa umbala kunye nokuvumba koboya beegusha. Umxholo wamanzi we-lanolin awukho ngaphezu kwe-0.25% (iqhekeza elikhulu), kwaye inani le-antioxidant lingafikelela kwi-0.02% (iqhekeza lobuninzi); i-European Union Pharmacopoeia 2002 icacisa ukuba i-butylated hydroxytoluene (BHT), engaphantsi kwe-200mg / kg, inokongezwa njenge-antioxidant. I-Anhydrous lanolin yinto etyheli ekhanyayo, enamafutha efana ne-wax enevumba elincinane. I-lanolin enyibilikisiweyo iyabonakala okanye iphantse yabonakala elulwelo olutyheli. Inyibilika ngokulula kwi-benzene, i-chloroform, i-ether, njl., ayinyibiliki emanzini, ukuba ixutywe namanzi, inokufunxa kancinci kancinci amanzi alingana namaxesha ama-2 ubunzima bayo ngaphandle kokwahlulwa.

I-Lanolin isetyenziswa ngokubanzi kumalungiselelo eziyobisi kunye nezithambiso. I-Lanolin ingasetyenziselwa njenge-hydrophobic carrier ukulungiselela i-creams yamanzi kwi-oyile kunye namafutha. Xa ixutywe neoli yemifuno efanelekileyo okanye i-petroleum jelly, ivelisa umphumo we-emollient kwaye ingena esikhumbeni, ngaloo ndlela ikhuthaza ukufunxa kweziyobisi. I-Lanolin ayihlukani malunga nokuphindwe kabini inani layo lamanzi kwaye i-emulsion ebangelwayo ayinakuchaphazeleka kwi-rancidity ngexesha lokugcinwa.

Umphumo we-emulsifying we-lanolin ikakhulu ngenxa yobuchule obunamandla be-emulsifying ye-α- kunye ne-β-diols equlethwe kuyo, ngaphezu kwe-cholesterol esters kunye ne-alcohols ephezulu enegalelo kwi-emulsifying effect. I-Lanolin ithambisa kwaye ithambisa ulusu, inyuse umgangatho wamanzi angaphezulu kolusu, kwaye isebenze njenge-moisturizer ngokuthintela ukulahleka kokudluliselwa kwamanzi kwi-epidermal.

I-Lanolin kunye ne-non-polar hydrocarbons, njenge-oyile ye-mineral kunye ne-petroleum jelly yahlukile, i-hydrocarbon emollients ngaphandle kwe-emulsifying isakhono, phantse ayifuntshwa yi-stratum corneum, iqiniswe ngokufunxa kunye nokugcinwa kwesiphumo se-emollliency kunye ne-moisturizing. Ikakhulu isetyenziswa kuzo zonke iintlobo zeekhrimu zokhathalelo lwesikhumba, izithambiso zonyango, iimveliso zelanga kunye neemveliso zokhathalelo lweenwele, ezikwasetyenziswa kwizithambiso zemilebe kunye neesepha.

I-lanolin ehlanjululweyo ye-Ultra ikhuselekile kwaye ngokuqhelekileyo ithathwa njengento engeyona inetyhefu kwaye ayinakucaphukisa. Amathuba okuba ne-lanolin allergy kubemi kuqikelelwa ukuba malunga ne-5%.

ILanolin nayo inefuthe lokuthambisa eluswini. Iyondla ngobunono umphezulu wolusu, ilungelelanisa imveliso yeoli, kwaye iphucula ukunwebeka nokukhanya kolusu.

I-Lanolin nayo ineempawu ezithile zokubuyisela. Xa ulusu lwethu luvuselelwe okanye lonakaliswe yindawo yangaphandle, i-lanolin inokukhuthaza ukuvuselelwa nokulungiswa kweeseli zesikhumba kunye nokukhawuleza ukubuyiswa kweendawo ezonakalisiweyo. Ngoko ke, kwabanye abantu abaneengxaki ezincinci zesikhumba, ezifana nesikhumba esomileyo, ubomvu, ukukhupha, njl., Ukusetyenziswa kwemveliso yokunakekelwa kwesikhumba equkethe i-lanolin inokudlala indima ethile ekunciphiseni nasekulungiseni.

I-Lanolin nayo inefuthe elithile lokulwa ne-antioxidant. Ityebile kwiivithamini kunye ne-antioxidants ezinokuthi zenze i-radicals yamahhala kwaye icothise inkqubo yokuguga kwesikhumba.

Njengesithako esiqhelekileyo sokuthambisa sendalo, i-lanolin ineempembelelo ezahlukeneyo kunye nemisebenzi kwiimveliso zokhathalelo lwesikhumba. I-moisturize ngokufanelekileyo kwaye iyondla, ithambisa ulusu, ilungisa iindawo ezonakalisiweyo kwaye ilwe ne-oxidation. Ukuba ufuna ukuba nolusu olufumileyo, olondlekileyo, oluthambileyo nolugudileyo, khetha imveliso ye-skincare ene-lanolin. Ukusetyenziswa kwexesha elide kweemveliso ze-skincare ezinezithako ze-lanolin kunokwenza ulusu lwakho lube lulutsha kwaye luqine, kwaye luthintele ukuphuhliswa kwemigca emihle kunye nemibimbi.
