Nā waiwai a me nā hoʻohana o ka lanolin

Lanolinahe huahana ʻaoʻao i loaʻa mai ka holoi ʻana o ka hulu hipa ʻālohilohi, kahi i unuhi ʻia a hana ʻia e hana i ka lanolin i hoʻomaʻemaʻe ʻia, i ʻike ʻia hoʻi ʻo ka wax hipa. ʻAʻohe ona triglycerides a he mea huna ia mai nā ʻōpū sebaceous o ka ʻili hipa.
Ua like ke ʻano o ka Lanolin me ka sebum kanaka a ua hoʻohana nui ʻia i nā huahana lāʻau hoʻonani a me nā huahana lāʻau topical. Hoʻomaʻemaʻe ʻia ʻo Lanolin a ua hana ʻia nā ʻano lanolin like ʻole ma o nā kaʻina hana like ʻole e like me ka fractionation, saponification, acetylation a me ethoxylation. Eia kahi hoʻolauna pōkole i nā waiwai a me nā noi o ka lanolin.
Lanolin wai ʻole
Puna:He mea waxy maʻemaʻe i loaʻa ma ka holoi ʻana, hoʻohemo kala a me ka hoʻohemo ʻala i ka hulu hipa. ʻAʻole ʻoi aku ka nui o ka wai o ka lanolin ma mua o 0.25% (hapa nui), a ʻo ka nui o ka antioxidant a hiki i ka 0.02% (hapa nui); Ua kuhikuhi ʻo EU Pharmacopoeia 2002 hiki ke hoʻohui ʻia ka butylhydroxytoluene (BHT) ma lalo o 200mg/kg ma ke ʻano he antioxidant.
Nā Waiwai:He melemele māmā, ʻaila, waxy ka lanolin anhydrous me kahi ʻala iki. He wai melemele moakaka a kokoke moakaka paha ka lanolin i hoʻoheheʻe ʻia. He maʻalahi ke hoʻoheheʻe ʻia i loko o ka benzene, chloroform, ether, a pēlā aku. ʻAʻole ia e hoʻoheheʻe ʻia i ka wai. Inā hui pū ʻia me ka wai, hiki iā ia ke omo mālie i ka wai e like me 2 mau manawa o kona kaumaha ponoʻī me ka ʻole o ka hoʻokaʻawale ʻana.
Nā noi:Hoʻohana nui ʻia ʻo Lanolin i nā hoʻomākaukau lāʻau lapaʻau topical a me nā mea hoʻonani. Hiki ke hoʻohana ʻia ʻo Lanolin ma ke ʻano he mea lawe hydrophobic no ka hoʻomākaukau ʻana i nā kirīmi a me nā poni wai-i-ka-ʻaila. Ke hui pū ʻia me nā aila mea kanu kūpono a i ʻole ka petroleum jelly, hana ia i kahi hopena emollient a komo i loko o ka ʻili, no laila e maʻalahi ai ka omo ʻana o ka lāʻau.Lanolinai hui pū ʻia me kahi pālua o ka nui o ka wai ʻaʻole e hoʻokaʻawale, a ʻo ka emulsion hopena e emi iki ka pala i ka mālama ʻana.
ʻO ka hopena emulsifying o ka lanolin ma muli nui o ka mana emulsifying ikaika o ka α- a me β-diols i loko, a me ka hopena emulsifying o nā esters cholesterol a me nā waiʻona kiʻekiʻe. Hoʻowali a hoʻomālielie ʻo Lanolin i ka ʻili, hoʻonui i ka nui o ka wai o ka ʻili, a hana ma ke ʻano he mea hoʻomaʻū ma ke kāohi ʻana i ka nalowale o ka hoʻoili wai epidermal.
ʻAʻole e like me nā hydrocarbons non-polar e like me ka ʻaila mineral a me ka petroleum jelly, ʻaʻohe hiki ke emulsifying o ka lanolin a ʻaʻole ia e komo nui ʻia e ka stratum corneum, e hilinaʻi nui ana i ka hopena omo o ka emolliency a me ka moisturization. Hoʻohana nui ʻia ia i nā ʻano kirīmi mālama ʻili āpau, nā ʻaila lāʻau lapaʻau, nā huahana sunscreen a me nā huahana mālama lauoho, a hoʻohana pū ʻia i nā mea hoʻonani lipstick a me nā kopa, a pēlā aku.
Palekana:ʻAʻole pilikia loalanolinahe palekana a ua manaʻo pinepine ʻia he mea ʻawaʻawa ʻole a ʻaʻole hoʻonāukiuki, a ua manaʻo ʻia ka likelika o ka maʻi allergy lanolin i loko o ka heluna kanaka ma kahi o 5%.
