Iimpawu kunye nokusetyenziswa kwe-lanolin

I-Lanolinyimveliso efunyenwe emva kokuhlanjwa koboya oburhabaxa, ekhutshwayo kwaye icutshungulwe ukuze kuveliswe i-lanolin ecociweyo, eyaziwa ngokuba yi-sheep wax. Ayinazo ii-triglycerides kwaye yimveliso evela kwiindlala zesikhumba segusha.
I-Lanolin ifana ngokwakhiwa kwayo ne-sebum yomntu kwaye isetyenziswa kakhulu kwiimveliso zezithambiso kunye namayeza asetyenziswa ekhaya. I-Lanolin iyacocwa kwaye iintlobo ngeentlobo ze-lanolin ziveliswa ngeenkqubo ezahlukeneyo ezifana nokuqhekeka, i-saponification, i-acetylation kunye ne-ethoxylation. Oku kulandelayo yintshayelelo emfutshane kwiipropati kunye nokusetyenziswa kwe-lanolin.
I-lanolin engenamanzi
Umthombo:Into ecocekileyo efana newax efunyenwe ngokuhlamba, ukususa umbala kunye nokususa ivumba loboya begusha. Umthamo wamanzi we-lanolin awudluli kwi-0.25% (inxalenye yobunzima), kwaye ubungakanani be-antioxidant bufikelela kwi-0.02% (inxalenye yobunzima); I-EU Pharmacopoeia 2002 icacisa ukuba i-butylhydroxytoluene (BHT) engaphantsi kwe-200mg/kg inokongezwa njenge-antioxidant.
Iipropati:I-lanolin engenamanzi yinto etyheli kancinci, enamafutha, efana newax enevumba elincinci. I-lanolin enyibilikisiweyo lulwelo olutyheli olucacileyo okanye oluphantse lubonakale. Inyibilika lula kwi-benzene, i-chloroform, i-ether, njl. Ayinyibiliki emanzini. Ukuba ixutywe namanzi, ingafunxa amanzi kancinci ngokulinganayo nobunzima bayo obuphindwe kabini ngaphandle kokuhlukana.
Izicelo:I-Lanolin isetyenziswa kakhulu kwimithi kunye nezinto zokuthambisa ezisetyenziswa kwiindawo ezahlukeneyo. I-Lanolin ingasetyenziswa njengesithwali esinganyangekiyo xa kulungiselelwa iikhrimu kunye neeoyile ezifakwe emanzini. Xa ixutywe neeoyile zemifuno ezifanelekileyo okanye ijeli yepetroleum, ivelisa isiphumo sokuthambisa kwaye ingena eluswini, ngaloo ndlela iququzelela ukufunxwa kwamayeza.I-Lanolinxa ixutywe namanzi aphindwe kabini ayihlukani, kwaye i-emulsion ephumayo ayinakwenzeka ukuba ibole xa igcinwe.
Isiphumo sokuxubha se-lanolin sibangelwa ngamandla amakhulu okuxubha e-α- kunye ne-β-diols eziquletheyo, kunye nesiphumo sokuxubha se-cholesterol esters kunye nee-alcohols eziphezulu. I-Lanolin ithambisa kwaye ithambise ulusu, yonyusa umxholo wamanzi kumphezulu wolusu, kwaye isebenza njengearhente yokumanzisa ngokuthintela ukulahleka kokudluliselwa kwamanzi e-epidermal.
Ngokungafaniyo neehydrocarbons ezingezizo iipolar ezifana neoyile yeminerali kunye ne-petroleum jelly, i-lanolin ayinayo i-emulsifying kwaye ayifunxwa yi-stratum corneum, ixhomekeke kakhulu kwisiphumo sokufunxa i-emolliency kunye nokufuma. Isetyenziswa kakhulu kuzo zonke iintlobo zeekhrimu zokhathalelo lolusu, amafutha okugcoba amayeza, iimveliso ze-sunscreen kunye neemveliso zokhathalelo lweenwele, kwaye ikwasetyenziswa nakwizithambiso zobuhle zelipstick kunye neesepha, njl.njl.
Ukhuseleko:Ithambile kakhului-lanolinikhuselekile kwaye idla ngokuthathwa njengento engenabungozi kwaye engacaphukisiyo, kwaye amathuba okuba ne-lanolin aleji ebantwini aqikelelwa ukuba amalunga ne-5%.
