Katundu ndi ntchito za lanolin

Lanolinndi chinthu china chomwe chimapezedwa kuchokera ku kutsuka ubweya wosalala, womwe umachotsedwa ndikukonzedwa kuti upange lanolin woyengedwa, womwe umadziwikanso kuti sera ya nkhosa. Ulibe triglycerides iliyonse ndipo ndi chinthu chotuluka m'matenda a sebaceous a khungu la nkhosa.
Lanolin ndi yofanana ndi sebum ya munthu ndipo yagwiritsidwa ntchito kwambiri mu zodzoladzola ndi mankhwala opaka pakhungu. Lanolin imayengedwa bwino ndipo zinthu zosiyanasiyana zochokera ku lanolin zimapangidwa kudzera mu njira zosiyanasiyana monga kugawa, kugawa, kugawa, ndi kugawa. Izi ndi mwachidule kufotokoza za makhalidwe ndi ntchito za lanolin.
Lanolin yopanda madzi
Chitsime:Chinthu choyera ngati phula chomwe chimapezeka potsuka, kuchotsa utoto ndi kuchotsa fungo loipa la ubweya wa nkhosa. Madzi a lanolin sapitirira 0.25% (gawo lalikulu), ndipo kuchuluka kwa antioxidant kufika pa 0.02% (gawo lalikulu); EU Pharmacopoeia 2002 imati butylhydroxytoluene (BHT) yochepera 200mg/kg ikhoza kuwonjezeredwa ngati antioxidant.
Katundu:Lanolin yopanda madzi ndi chinthu chachikasu chopepuka, chamafuta, komanso chokhala ndi fungo lochepa. Lanolin yosungunuka ndi madzi achikasu owonekera kapena pafupifupi owonekera. Amasungunuka mosavuta mu benzene, chloroform, ether, ndi zina zotero. Sasungunuka m'madzi. Ngati atasakanikirana ndi madzi, amatha kuyamwa madzi pang'onopang'ono mofanana ndi kulemera kwake kawiri popanda kupatukana.
Mapulogalamu:Lanolin imagwiritsidwa ntchito kwambiri popanga mankhwala ndi zodzoladzola. Lanolin ingagwiritsidwe ntchito ngati chonyamulira cha hydrophobic pokonzekera mafuta ndi mafuta odzola omwe amaikidwa m'mafuta. Ikasakanizidwa ndi mafuta oyenera a masamba kapena mafuta odzola, imapanga mphamvu yofewa ndikulowa pakhungu, motero imathandizira kuyamwa kwa mankhwala.LanolinKusakaniza ndi madzi pafupifupi kawiri sikulekanitsa, ndipo emulsion yomwe imabwera chifukwa cha izi siingakhale yotupa kwambiri ikasungidwa.
Mphamvu ya lanolin yolimbitsa thupi imachitika makamaka chifukwa cha mphamvu yamphamvu ya ma α- ndi β-diols omwe ali nawo, komanso mphamvu ya emulsifying ya ma cholesterol esters ndi ma alcohols apamwamba. Lanolin imapaka mafuta ndi kufewetsa khungu, imawonjezera madzi pamwamba pa khungu, ndipo imagwira ntchito ngati chonyowetsa poletsa kutayika kwa madzi a epidermal.
Mosiyana ndi ma hydrocarbons osakhala a polar monga mafuta amchere ndi mafuta odzola, lanolin ilibe mphamvu yopangira emulsifying ndipo simayamwa ndi stratum corneum, kudalira kwambiri mphamvu yoyamwa emollience ndi chinyezi. Imagwiritsidwa ntchito makamaka mu mitundu yonse ya mafuta osamalira khungu, mafuta odzola, zinthu zoteteza ku dzuwa ndi zinthu zosamalira tsitsi, komanso imagwiritsidwa ntchito mu zodzoladzola zokongola za milomo ndi sopo, ndi zina zotero.
Chitetezo:Wofewa kwambirilanolinNdi yotetezeka ndipo nthawi zambiri imaonedwa ngati chinthu chopanda poizoni komanso chosakwiyitsa, ndipo mwayi wokhala ndi ziwengo za lanolin mwa anthu ambiri ukuyembekezeka kukhala pafupifupi 5%.
