Lanolin (Lanolin, E913) - glazier. Wulu huluhulu, ʻilā holoholona i loaʻa ma ka holoi ʻana i ka hulu hipa.
ʻO ka nui viscous brownish-melemele nuipa. ʻOkoʻa ia mai nā wīwī ʻē aʻe me kahi kiʻekiʻe o nā sterols (ma kahi, kolesterol). Hoʻokomo maikaʻi ʻia ʻo Lanolin i ka ʻili a loaʻa kahi hopena palupalu. ʻO kēia kahi mānoanoa, viscous o ka melemele a melemele-ʻeleʻele, kahi ʻala kūikawā, hoʻoheheʻe ʻia i kahi mahana o 36-42 ° C.
He paʻakikī loa ka hoʻohui ʻana o ka lanolin a ʻaʻole i hoʻopaʻa piha ʻia. ʻO ke kumu, he hui o nā esters o nā alcohols molekiola kiʻekiʻe (kolesterol, isocholesterol, a me nā mea ʻē aʻe) me nā waikawa momona kiʻekiʻe (myristic, palmitic, cerotinic, a me nā mea ʻē aʻe) a me nā waiʻona molekiola kiʻekiʻe. Wahi a nā waiwai o lanolin, kokoke ia i ka sebum kanaka.
I nā huaʻōlelo kemika, he miki ʻole ia, kūlike ʻole a paʻa hoʻi i ka wā e waiho ana. ʻO ka waiwai ʻoi loa o ka lanolin ka hiki iā ia ke emulsify a hiki i ka 180-200% (o kona kaupaona ponoʻī) i ka wai, a i ka 140% glycerol a ma kahi o 40% ethanol (70% concentration) e hana i ka wai / ʻaila emulsions. ʻO ka hoʻohui ʻana o kahi lanolin liʻiliʻi i nā momona a me nā hydrocarbons e hoʻonui nui i ko lākou hiki ke kāwili me ka wai a me nā haʻina wai, i alakaʻi ʻia ai i ka hoʻohana ākea i ka hui ʻana o nā waihona lipophilic-hydrophilic.
Hoʻohana ākea ia ma ke ʻano he ʻāpana o nā cosmetics-cream, a me nā mea ʻē aʻe, i ka lāʻau e hoʻohana ʻia ma ke ʻano he kumu no nā hamo like ʻole, a no ka palupalu ʻana o ka ʻili (i hui pū ʻia me ka nui o ka vaseline).
Loaʻa ka lanolin maʻemaʻe, hoʻomaʻemaʻe no nā wahine hānai (inoa inoa: Purelan, Lansinoh). Noi topically, kōkua ʻo lanolin e hoʻōla i nā māwae ma nā nipples a pale i ko lākou helehelena, a ʻaʻole koi i ka holoi ʻana ma mua o ka hānai ʻana (ʻaʻole weliweli no nā pēpē).
