Chakavanzika Chekuchengetedza Ganda: Lanolin Anhydrous

Chii chinonzi lanolin? Lanolin ndeye-chigadzirwa chakawanikwa kubva mukugezeswa kwemushonga wemvere dzemakushe, unotorwa nekugadzikiswa kugadzira lanolin yakacheneswa, inozivikanwawo sewakisi yehwai. Inosungirirwa kune makushe echidziviriro chegirisi, kunatsa uye kunatswa kweyero kana brownish-yellow mafuta, viscous uye inotsvedza kunzwa, izvo zvakakosha zvikamu sterols, mafuta anodhaka uye triterpene alcohols uye inenge yakaenzana huwandu hwemafuta acids anogadzirwa ne. iyo ester, uye shoma shoma yemahara fatty acids uye hydrocarbons.

Zvakafanana mukuumbwa kune sebum yemunhu, lanolin uye mabviro ayo ave kunyanya kushandiswa mucosmetics uye topical zvinodhaka zvigadzirwa. Lanolin inogona kugadzirwa kuita yakanatswa lanolin uye akasiyana lanolin derivatives kuburikidza neakasiyana maitiro akadai sefractionation, saponification, acetylation uye ethoxylation.

Anhydrous lanolin chinhu chakachena chewakisi chinowanikwa nekuwacha, kupendesa nekubvisa kunhuhwirira kwemvere dzemakwai. Mvura yelanolin haisi kupfuura 0.25% (chikamu chemazana), uye huwandu hwe antioxidant hunogona kusvika ku0.02% (chikamu chemazana); European Union Pharmacopoeia 2002 inotsanangura kuti butylated hydroxytoluene (BHT), iri pasi pe200mg/kg, inogona kuwedzerwa se antioxidant. Anhydrous lanolin ichinhu cheyero chakajeka, chakakora-chakafanana nenamo uye chinonhuwa zvishoma. Yanyungudutswa lanolin inoonekera kana kuti inenge inoonekera yero mvura. Inonyungudika nyore nyore mubenzene, chloroform, ether, nezvimwewo, isinganyunguriki mumvura, kana yakasanganiswa nemvura, inogona kunyura zvishoma nezvishoma mvura yakaenzana nekaviri uremu hwayo pasina kupatsanurwa.

Lanolin inoshandiswa zvakanyanya mukugadzirwa kwemishonga uye zvizoro. Lanolin inogona kushandiswa se hydrophobic mutakuri wekugadzirira kwemvura-mu-oiri makirimu uye zvizoro. Kana yakasanganiswa nemafuta emiriwo akakodzera kana petroleum jelly, inoburitsa emollient uye inopinda mukati meganda, nekudaro ichikurudzira kunwa kwezvinodhaka. Lanolin haiparadzanise kubva kaviri huwandu hwayo hwemvura uye iyo inokonzeresa emulsion haina kubatwa nerancidity panguva yekuchengetedza.

Iyo emulsifying mhedzisiro yelanolin inonyanya kukonzerwa nekusimba kwakasimba emulsifying kwea- uye β-diols iyo ine, kuwedzera kune cholesterol esters uye yakakwira madoro anobatsira pakuita emulsifying. Lanolin inozora uye inopfavisa ganda, inowedzera ganda pamusoro pemvura yemukati, uye inoita seyakanyorovesa nekuvhara kurasikirwa kwe epidermal kutamisa mvura.

Lanolin uye asiri-polar hydrocarbons, akadai semaminerari emafuta uye petroleum jelly akasiyana, hydrocarbon emollients pasina emulsifying kugona, anenge asina kubatwa neiyo stratum corneum, yakasimba nekutora uye kuchengetedza maitiro emollliency uye kunyorova. Inonyanya kushandiswa mumarudzi ese emakirimu ekuchengeta ganda, mafuta ekuzora, zvigadzirwa zvezuva uye zvigadzirwa zvekuchengeta bvudzi, zvinoshandiswawo mune lipstick cosmetics nesipo.

Ultra yakacheneswa lanolin yakachengeteka uye inowanzoonekwa sechinhu chisina chepfu uye chisingagumbure. Mikana yelanolin allergy muhuwandu inofungidzirwa kuva inenge 5%.

Lanolin inewo inopfavisa ganda. Inopa chikafu cheganda zvinyoro nyoro, inogadzirisa kugadzirwa kwemafuta, uye inovandudza elasticity yeganda uye kupenya.

Lanolin inewo zvimwe zvekudzorera. Kana ganda redu richimutswa kana kukuvadzwa nemamiriro ekunze, lanolin inogona kukurudzira kudzoreredzwa uye kugadziriswa kwemasero eganda uye kukurumidza kudzoreredzwa kwenzvimbo dzakakuvadzwa. Nokudaro, kune vamwe vanhu vane matambudziko maduku eganda, zvakadai seganda rakaoma, tsvuku, kusvuura, nezvimwewo, kushandiswa kwezvigadzirwa zvekuchengetedza ganda zvine lanolin zvinogona kuita rimwe basa mukugadzirisa nekugadzirisa.

Lanolin zvakare ine imwe antioxidant mhedzisiro. Yakapfuma muvhitamini uye antioxidants iyo inogona kumisa mahara radicals uye inonotsa kuchembera kweganda.

Seyakajairwa yakajairika yekunyorovesa musanganiswa, lanolin ine akasiyana mhedzisiro uye inoshanda muzvigadzirwa zvekuchengetedza ganda. Inonyatsonyorovesa uye inodyisa, inonyorovesa ganda, inogadzirisa nzvimbo dzakakanganisika uye inorwisa oxidation. Kana iwe uchida kuve neganda rakanyorova, rakadyiswa, rakapfava uye rakatsetseka, sarudza chigadzirwa cheganda chine lanolin. Kushandiswa kwenguva refu kwezvigadzirwa zvekuchengetedza ganda zvine lanolin zvinongedzo zvinogona kuita kuti ganda rako rive pwere uye rakasimba, uye kudzivirira kugadzirwa kwemitsara yakanaka nemakwinya.
