Katundu ndi kugwiritsa ntchito lanolin

Lanolinndi mankhwala opangidwa kuchokera pakutsuka ubweya wankhosa, womwe umachotsedwa ndi kukonzedwa kuti utulutse lanolin yoyengedwa, yomwe imadziwikanso kuti sera ya nkhosa.Lilibe triglycerides iliyonse ndipo ndi katulutsidwe ka sebaceous glands a khungu la nkhosa.
Lanolin ndi ofanana mu kapangidwe ka sebum ya munthu ndipo amagwiritsidwa ntchito kwambiri muzodzoladzola komanso mankhwala apakhungu.Lanolin imayengedwa ndipo zotumphukira zosiyanasiyana za lanolin zimapangidwa kudzera munjira zosiyanasiyana monga kugawa, saponification, acetylation ndi ethoxylation.Zotsatirazi ndizofotokozera mwachidule za katundu ndi ntchito za lanolin.
Lanolin yopanda madzi
Gwero:Phula loyera lomwe limapezeka potsuka, kuchotsa utoto komanso kununkhira ubweya wa nkhosa.Madzi a lanolin sali oposa 0.25% (chigawo cha misa), ndipo kuchuluka kwa antioxidant kufika ku 0.02% (gawo la misa);EU Pharmacopoeia 2002 imanena kuti butylhydroxytoluene (BHT) pansi pa 200mg/kg ikhoza kuwonjezeredwa ngati antioxidant.
Katundu:Anhydrous lanolin ndi chinthu chachikasu chopepuka, chamafuta, phula chomwe chimanunkhira pang'ono.Lanolin yosungunuka ndi madzi owoneka bwino kapena owoneka bwino achikasu.Imasungunuka mosavuta mu benzene, chloroform, ether, ndi zina zambiri. Sisungunuka m'madzi.Ngati atasakanizidwa ndi madzi, amatha kuyamwa pang'onopang'ono madzi ofanana ndi 2 nthawi za kulemera kwake popanda kupatukana.
Mapulogalamu:Lanolin imagwiritsidwa ntchito kwambiri popanga mankhwala apakhungu ndi zodzoladzola.Lanolin angagwiritsidwe ntchito ngati chonyamulira hydrophobic pokonzekera madzi-mu-mafuta zonona ndi mafuta.Mukasakaniza ndi mafuta abwino a masamba kapena mafuta odzola, amapanga emollient ndipo amalowa pakhungu, motero amathandizira kuyamwa kwa mankhwala.Lanolinwothira pafupifupi kawiri kuchuluka kwa madzi sikulekanitsa, ndipo chifukwa emulsion sakhala ndi rancidify mu yosungirako.
Mphamvu ya emulsifying ya lanolin makamaka chifukwa cha mphamvu yamphamvu ya emulsifying ya α- ndi β-diols yomwe ili nayo, komanso emulsifying zotsatira za cholesterol esters ndi mowa wambiri.Lanolin imatulutsa mafuta ndi kufewetsa khungu, imawonjezera madzi pakhungu, ndipo imakhala ngati chonyowa poletsa kutayika kwa madzi a epidermal.
Mosiyana ndi ma hydrocarboni omwe si a polar monga mafuta amchere ndi mafuta a petroleum, lanolin ilibe mphamvu yotulutsa emulsifying ndipo simalowetsedwa ndi stratum corneum, kudalira kwambiri kuyamwa kwa emolliency ndi moisturization.Amagwiritsidwa ntchito kwambiri mumitundu yonse yamafuta osamalira khungu, mafuta opaka mankhwala, zoteteza padzuwa ndi zinthu zosamalira tsitsi, komanso amagwiritsidwa ntchito muzodzola zodzikongoletsera ndi sopo, ndi zina zambiri.
Chitetezo:Wofewa kwambirilanolinndizotetezeka ndipo nthawi zambiri zimatengedwa ngati zinthu zopanda poizoni komanso zosakwiyitsa, ndipo kuthekera kwa ziwengo za lanolin mwa anthu akuyerekezeredwa kukhala pafupifupi 5%.
