Lanolinchinhu chinowanikwa kubva pakugezwa kweshinda yakakasharara, inotorwa yogadziriswa kuti ibudise lanolin yakacheneswa, inozivikanwawo segwai wax.Iyo haina chero triglycerides uye inovanda kubva kune sebaceous glands eganda remakwai.
Lanolin yakafanana mukuumbwa kune sebum yemunhu uye yakashandiswa zvakanyanya mucosmetic uye topical zvinodhaka zvigadzirwa.Lanolin inonatswa uye akasiyana lanolin derivatives anogadzirwa kuburikidza neakasiyana maitiro akadai sefractionation, saponification, acetylation uye ethoxylation.Iyi inotevera sumo pfupi yezvivakwa uye mashandisirwo elanolin.
Anhydrous lanolin
Kwakabva:Chinhu chakachena chenamo chinowanikwa nekuwacha, kubvisa ruvara uye kunhuwidza makushe emakwai.Mvura yelanolin haisi kupfuura 0.25% (chikamu chemazana), uye huwandu hwe antioxidant hunosvika 0.02% (chikamu chemazana);EU Pharmacopoeia 2002 inotsanangura kuti butylhydroxytoluene (BHT) iri pasi pe200mg/kg inogona kuwedzerwa se antioxidant.
Properties:Anhydrous lanolin chinhu cheyero chakareruka, chine mafuta, chinamo chine kamunhuhwi.Melted lanolin imvura inoonekera kana kuti inoonekera yero.Inonyungudika zviri nyore mubenzene, chloroform, ether, nezvimwewo. Haina kunyungudika mumvura.Kana yakasanganiswa nemvura, zvishoma nezvishoma inogona kutora mvura yakaenzana ne2 nguva yehuremu hwayo pasina kupatsanurwa.
Applications:Lanolin inoshandiswa zvakanyanya mukugadzirwa kwemishonga yemishonga uye cosmetics.Lanolin inogona kushandiswa se hydrophobic mutakuri wekugadzirira kwemvura-mu-mafuta makirimu nemafuta.Kana yakasanganiswa nemafuta emuriwo akakodzera kana petroleum jelly, inoburitsa emollient mhedzisiro uye inopinda mukati meganda, nokudaro kufambisa kubatwa kwezvinodhaka.Lanolinyakavhenganiswa neinenge kaviri chiyero chemvura hachiparadzanise, uye iyo inoguma emulsion kashoma kuita rancidify mukuchengetedza.
Iyo emulsifying mhedzisiro yelanolin inonyanya kukonzerwa nesimba rakasimba rekumisa emu α- uye β-diols iyo ine, pamwe neiyo emulsifying mhedzisiro yecholesterol esters uye yakakwira doro.Lanolin inozora uye inopfavisa ganda, inowedzera mvura yemukati meganda, uye inoshanda senge inonyorova nekuvhara kurasikirwa kwe epidermal kutamisa mvura.
Kusiyana neasiri-polar hydrocarbons akadai semaminerari emafuta uye petroleum jelly, lanolin haina emulsifying kugona uye hainyanyi kubatwa neiyo stratum corneum, ichitsamira padhuze neinomwisa mhedzisiro ye emolliency uye moisturization.Inonyanya kushandiswa mumarudzi ese emakirimu ekuchengeta ganda, mafuta ekuzora, zvigadzirwa zvezuva uye zvigadzirwa zvekuchengeta bvudzi, uye zvakare inoshandiswa mune lipstick runako zvizora uye sipo, nezvimwe.
Safety:Super delicatelanolinyakachengeteka uye inowanzoonekwa sechinhu chisina chepfu uye chisingaiti, uye mukana we lanolin allergy muhuwandu inofungidzirwa kuva inenge 5%.
