Nā waiwai a me ka hoʻohana ʻana o ka lanolin

Lanolinhe hua i loaa mai ka holoi ia ana o ka hulu hipa, i unuhiia a hanaia e hana i ka lanolin i hooheheeia, i kapaia hoi he palolo hipa.ʻAʻole loaʻa nā triglycerides a he mea huna ia mai ka ʻili sebaceous o ka ʻili hipa.
Ua like like ka Lanolin me ka sebum kanaka a ua hoʻohana nui ʻia i nā huahana hoʻonaninani a me nā huahana topical.Hoʻomaʻemaʻe ʻia ʻo Lanolin a hana ʻia nā ʻano derivatives lanolin ma o nā kaʻina like ʻole e like me ka fractionation, saponification, acetylation a me ka ethoxylation.ʻO kēia ka hoʻolauna pōkole i nā waiwai a me nā hoʻohana ʻana o ka lanolin.
Anhydrous lanolin
Puna:ʻO kahi mea waxy maʻemaʻe i loaʻa ma ka holoi ʻana, hoʻopau kala a me ka hoʻohemo ʻana i ka hulu hipa.ʻAʻole iʻoi aku ka nui o ka wai o ka lanolin ma mua o 0.25% (mass fraction), aʻo ka nui o ka antioxidant a hiki i ka 0.02% (mass fraction);Ua kuhikuhi ʻo EU Pharmacopoeia 2002 e hiki ke hoʻohui ʻia ka butylhydroxytoluene (BHT) ma lalo o 200mg/kg ma ke ʻano he antioxidant.
Nā waiwai:ʻO ka lanolin anhydrous he mea melemele māmā, ʻaila, waxy me kahi ʻala iki.ʻO ka lanolin i hoʻoheheʻe ʻia he wai melemele ʻalohi a kokoke paha.Hiki ke hoʻoheheʻe ʻia i loko o benzene, chloroform, ether, etc. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai.Inā hui pū ʻia me ka wai, hiki iā ia ke komo mālie i ka wai e like me 2 mau manawa o kona kaumaha ponoʻī me ka hoʻokaʻawale ʻole.
Nā noi:Hoʻohana nui ʻia ʻo Lanolin i nā lāʻau lapaʻau topical a me nā mea hoʻonaninani.Hiki ke hoʻohana ʻia ʻo Lanolin ma ke ʻano he mea lawe hydrophobic no ka hoʻomākaukau ʻana i nā ʻaila wai-i-ʻaila a me nā ʻaila.Ke hui pū ʻia me nā aila meaʻai kūpono a i ʻole ka petroleum jelly, hoʻopuka ia i kahi hopena emollient a komo i loko o ka ʻili, no laila e hoʻomaʻamaʻa i ka lawe ʻana i ka lāʻau.Lanolinhui 'ia me ka ma kahi o ka palua ka nui o ka wai, aole e hookaawale, a me ka hopena o ka emulsion mea emi paha e rancidify i loko o ka waihona.
ʻO ka hopena emulsifying o ka lanolin ka mea nui ma muli o ka mana emulsifying ikaika o ka α- a me β-diols i loko, a me ka hopena emulsifying o nā cholesterol esters a me nā waiʻona kiʻekiʻe.Hoʻomaʻamaʻa ʻo Lanolin i ka ʻili, hoʻonui i ka wai o ka ʻili o ka ʻili, a hana ma ke ʻano he mea hoʻomaʻemaʻe ma ke kāohi ʻana i ka nalowale o ka wai epidermal.
ʻAʻole like me nā hydrocarbons non-polar e like me ka aila mineral a me ka petroleum jelly, ʻaʻohe hiki emulsifying ka lanolin a paʻakikī ʻole ʻia e ka stratum corneum, e hilinaʻi nui ana i ka hopena o ka emolliency a me ka moisturization.Hoʻohana nui ʻia ia i nā ʻano ʻili mālama ʻili āpau, nā ʻaila lāʻau lapaʻau, nā huahana sunscreen a me nā huahana mālama lauoho, a hoʻohana pū ʻia i nā lipstick nani a me nā kopa, etc.
Palekana:Paʻaleʻa loalanolinpalekana a manaʻo pinepine ʻia he mea ʻawaʻawa ʻole a hoʻonāukiuki ʻole, a ʻo ka nui o ka maʻi allergy lanolin i ka heluna kanaka i manaʻo ʻia ma kahi o 5%.
