Kodi lanolin ndi chiyani? Lanolin ndi mankhwala opangidwa kuchokera ku zotsukira zotsukira ubweya, zomwe zimachotsedwa ndikusinthidwa kuti apange lanolin yoyengedwa, yomwe imadziwikanso kuti sera ya nkhosa. Zimamangiriridwa ku ubweya wa katulutsidwe wa mafuta, kuyenga ndi kuyenga mafuta achikasu kapena bulauni-wachikasu, kumverera koterera komanso koterera, zigawo zazikuluzikulu ndi ma sterols, ma alcohols amafuta ndi ma alcohols a triterpene komanso pafupifupi kuchuluka kwamafuta acids opangidwa ndi ester, ndi kachulukidwe kakang'ono ka mafuta acids aulere ndi ma hydrocarbon.
Mofanana ndi mapangidwe a sebum aumunthu, lanolin ndi zotuluka zake zakhala zikugwiritsidwa ntchito kwambiri muzodzoladzola ndi mankhwala osokoneza bongo. Lanolin imatha kupangidwa kukhala lanolin yoyengedwa ndi zotumphukira zosiyanasiyana za lanolin kudzera munjira zosiyanasiyana monga kugawa, saponification, acetylation ndi ethoxylation.
Anhydrous lanolin ndi phula loyera lomwe limapezeka potsuka, kukongoletsa ndi kununkhira ubweya wa nkhosa. Madzi a lanolin sali oposa 0,25% (chigawo cha misa), ndipo kuchuluka kwa antioxidant kungakhale mpaka 0.02% (gawo la misa); European Union Pharmacopoeia 2002 imanena kuti butylated hydroxytoluene (BHT), yomwe ili yochepera 200mg/kg, ikhoza kuwonjezeredwa ngati antioxidant. Anhydrous lanolin ndi chinthu chachikasu chopepuka, chonyezimira ngati sera komanso kafungo kakang'ono. Lanolin yosungunuka imakhala yowonekera kapena pafupifupi yowoneka bwino yamadzi achikasu. Amasungunuka mosavuta mu benzene, chloroform, ether, etc., osasungunuka m'madzi, ngati atasakanikirana ndi madzi, amatha kuyamwa pang'onopang'ono madzi ofanana ndi 2 kulemera kwake popanda kupatukana.
Lanolin chimagwiritsidwa ntchito apakhungu mankhwala kukonzekera ndi zodzoladzola. Lanolin angagwiritsidwe ntchito ngati chonyamulira hydrophobic pokonzekera madzi-mu-mafuta creams ndi mafuta. Mukasakaniza ndi mafuta a masamba abwino kapena mafuta odzola, amapanga emollient ndipo amalowa pakhungu, motero amalimbikitsa kuyamwa kwa mankhwala. Lanolin salekanitsa pafupifupi kawiri kuchuluka kwa madzi ake ndipo chifukwa emulsion si atengeke rancidity pa yosungirako.
Mphamvu ya emulsifying ya lanolin makamaka chifukwa cha mphamvu yamphamvu ya emulsifying ya α- ndi β-diols yomwe ili nayo, kuphatikizapo mafuta a kolesterolini ndi zakumwa zoledzeretsa zomwe zimathandiza kuti emulsifying effect. Lanolin imatulutsa mafuta ndi kufewetsa khungu, imawonjezera madzi pakhungu, ndipo imakhala ngati moisturizer poletsa kutayika kwa madzi a epidermal.
Lanolin ndi si polar hydrocarbons, monga mchere mafuta ndi mafuta odzola ndi osiyana, hydrocarbon emollients popanda emulsifying luso, pafupifupi osati odzipereka ndi stratum corneum, mwamphamvu ndi mayamwidwe ndi posungira zotsatira za emolliency ndi moisturizing. Amagwiritsidwa ntchito makamaka mumitundu yonse yamafuta osamalira khungu, mafuta opaka mankhwala, zoteteza ku dzuwa ndi zinthu zosamalira tsitsi, zomwe zimagwiritsidwanso ntchito muzodzola za milomo ndi sopo.
Ultra refined lanolin ndi yotetezeka ndipo nthawi zambiri imatengedwa kuti ndi yopanda poizoni komanso yosakwiyitsa. Kuthekera kwa ziwengo za lanolin mwa anthu akuyerekezeredwa kukhala pafupifupi 5%.
Lanolin imakhalanso ndi mphamvu yofewa pakhungu. Imadyetsa khungu pang'onopang'ono, imachepetsa kupanga mafuta, komanso imapangitsa kuti khungu likhale losalala komanso lowala.
Lanolin imakhalanso ndi zinthu zobwezeretsa. Khungu lathu likalimbikitsidwa kapena kuwonongeka ndi chilengedwe chakunja, lanolin ikhoza kulimbikitsa kusinthika ndi kukonzanso maselo a khungu ndikufulumizitsa kubwezeretsedwa kwa malo owonongeka. Choncho, kwa anthu ena omwe ali ndi mavuto ang'onoang'ono a khungu, monga khungu louma, kufiira, kupukuta, ndi zina zotero, kugwiritsa ntchito mankhwala osamalira khungu omwe ali ndi lanolin amatha kuchitapo kanthu pothandizira ndi kukonza.
Lanolin imakhalanso ndi antioxidant kwenikweni. Lili ndi mavitamini komanso ma antioxidants omwe amatha kusokoneza ma free radicals ndikuchepetsa kukalamba kwa khungu.
Monga chinthu chodziwika bwino chachilengedwe chonyowetsa, lanolin imakhala ndi zotsatira zosiyanasiyana komanso ntchito pazosamalira khungu. Imafewetsa bwino ndikudyetsa, imachepetsa khungu, imakonza malo owonongeka ndikumenyana ndi okosijeni. Ngati mukufuna kukhala ndi khungu lonyowa, lopatsa thanzi, lofewa komanso losalala, sankhani mankhwala osamalira khungu omwe ali ndi lanolin. Kugwiritsa ntchito nthawi yayitali kwa zinthu zosamalira khungu zomwe zimakhala ndi zosakaniza za lanolin zimatha kupangitsa khungu lanu kukhala lachichepere komanso lolimba, ndikuletsa kukula kwa mizere yabwino ndi makwinya.
