Lanolinyimveliso efunyenwe ekuhlanjweni koboya oburhabaxa, obutsalwa kwaye bulungiswe ukuvelisa i-lanolin esulungekisiweyo, ekwaziwa ngokuba yi-wax yeegusha.Ayiqulathanga naziphi na i-triglycerides kwaye yincindi ephuma kumadlala amdaka esikhumba segusha.
I-Lanolin iyafana ngokwakhiwa kwe-sebum yomntu kwaye isetyenziswe ngokubanzi kwiimveliso zamachiza zokuthambisa kunye nezihloko.I-Lanolin isulungekisiwe kwaye iintlobo ezahlukeneyo ze-lanolin ziveliswa ngeenkqubo ezahlukeneyo ezifana ne-fractionation, i-saponification, i-acetylation kunye ne-ethoxylation.Oku kulandelayo sisingeniso esifutshane kwiipropati kunye nokusetyenziswa kwe-lanolin.
I-lanolin engenamanzi
Umthombo:Into esulungekileyo ye-waxy efunyenwe ngokuhlanjwa, ukukhupha umbala kunye nokuvumba koboya begusha.Umxholo wamanzi we-lanolin awukho ngaphezu kwe-0.25% (iqhekeza elikhulu), kwaye inani le-antioxidant lifikelela kwi-0.02% (iqhekeza lobuninzi);I-EU Pharmacopoeia 2002 ichaza ukuba i-butylhydroxytoluene (BHT) engaphantsi kwe-200mg / kg inokongezwa njenge-antioxidant.
Iinkcazelo ngeempawu:I-Anhydrous lanolin yinto etyheli ekhanyayo, enamafutha, ene-waxy enevumba elincinane.I-lanolin enyibilikisiweyo lulwelo olucacileyo okanye oluphantse lubonakale ngaphaya komthubi.Inyibilika lula kwibenzene, iklorofomu, i-ether, njl njl. Ayinyibiliki emanzini.Ukuba ixutywe namanzi, inokufunxa ngokuthe ngcembe amanzi alingana namaxesha ama-2 obunzima bayo ngaphandle kokwahlulwa.
Usetyenziso:I-Lanolin isetyenziswa ngokubanzi kumalungiselelo amayeza kunye nezithambiso.I-Lanolin ingasetyenziselwa njenge-hydrophobic carrier yokulungiswa kwamanzi kwi-oyile creams kunye namafutha.Xa ixutywe neoli yemifuno efanelekileyo okanye i-petroleum jelly, ivelisa umphumo we-emollient kwaye ingena esikhumbeni, ngaloo ndlela iququzelela ukufunxa kweziyobisi.Lanolinixutywe malunga nokuphindwe kabini inani lamanzi lingahlukani, kwaye i-emulsion ebangelwayo ayinakwenzeka ukuba i-rancidify kwindawo yokugcina.
Umphumo we-emulsifying we-lanolin ikakhulu ngenxa yamandla e-emulsifying anamandla e-α- kunye ne-β-diols equlethwe, kunye nefuthe le-emulsifying ye-cholesterol esters kunye ne-alcohols ephezulu.I-Lanolin ithambisa kwaye ithambisa ulusu, inyusa umthamo wamanzi kumphezulu wolusu, kwaye isebenze njengesixhobo sokumanzisa ngokuthintela ukulahleka kokudluliselwa kwamanzi kwi-epidermal.
Ngokungafaniyo ne-non-polar hydrocarbons ezifana ne-oyile ye-mineral kunye ne-petroleum jelly, i-lanolin ayinaso isakhono se-emulsifying kwaye ayifuni ukufunxwa yi-stratum corneum, ixhomekeke ngokusondeleyo kwimpembelelo yokufunxa i-emollientation kunye ne-moisturization.Isetyenziswa ikakhulu kuzo zonke iintlobo zeekhrimu zokhathalelo lwesikhumba, i-ointment zonyango, iimveliso zelanga kunye neemveliso zokhathalelo lweenwele, kwaye zikwasetyenziswa kwi-lipstick yobuhle bokuthambisa kunye nesepha, njl.
Ukhuseleko:Uthambile kakhululanolinikhuselekile kwaye ngokuqhelekileyo ithathwa njengento engeyiyo ityhefu kwaye ingenabuhlungu, kwaye amathuba okuba ne-lanolin allergy kubemi kuqikelelwa ukuba malunga ne-5%.
