Cov quav ciab no tuaj yeem piav qhia tias yog ib qho nyuaj, nkig, daj-xim av, aromatic, thiab opaque rau cov khoom siv translucent.
Cov tshuaj formula rau cov khoom siv waxy no tuaj yeem muab tau raws li C 31H64 Cov molar pawg ntawm Candelilla wax yog 436.84 g / mol. Nws melting point yog nyob rau hauv thaj tsam ntawm 68.5 - 72.5 degrees Celsius. Txawm li cas los xij, nws qhov kub kub yog siab tshaj 240 degrees Celsius. Nws yog insoluble hauv dej. Txawm li cas los xij, nws yog soluble hauv ethanol, benzene, thiab roj av ether. Lub teeb nyem ntawm qhov sib xyaw no tuaj yeem muab tau li 313.1 degrees Celsius. Ntxiv mus, cov koob tshuaj tuag ntawm Candelilla wax yog >5000 mg / kg rau nas los ntawm kev tswj qhov ncauj.
Cov khoom no muaj cov ntsiab lus siab ntawm hydrocarbons, uas yog nyob ib ncig ntawm 50% ntawm tag nrho cov khoom siv, thiab cov hydrocarbons feem ntau muaj chains nrog 29-33 carbons. Cov quav ciab no muaj cov esters uas muaj qhov hnyav molecular, cov kua qaub dawb, thiab qee cov khoom sib txuas xws li triterpenoid esters.
Peb tuaj yeem tau txais Candelilla wax los ntawm kev npau npau nplooj thiab stems ntawm tsob ntoo nrog dilute sulfuric acid. Qhov no ua rau "cerote," uas yog tom qab ntawd skimmed los ntawm qhov chaw thiab nws tau ua tiav ntxiv. Cov neeg tsim khoom tsim tawm txog 900 tons ntawm cov quav ciab no hauv cov qauv no txhua xyoo.
Muaj ntau yam kev siv ntawm Candelilla wax, suav nrog nws siv los ua khoom noj khoom haus thiab siv los ua tus neeg sawv cev glazing. Nws yog siv nyob rau hauv kev lag luam cosmetic raws li ib feem nyob rau hauv di ncauj balms thiab lotion tuav. Lwm qhov tseem ceeb yog siv los ua ib qho khoom siv rau zom cov pos hniav. Tsis tas li ntawd, peb tuaj yeem siv nws los hloov Carnauba wax thiab beeswax.
Carnauba Wax yog dab tsi?
Carnauba wax yog ib hom khoom siv ntuj tsim uas muaj cov roj ntsha esters, fatty alcohols, acids, thiab hydrocarbons. Cov quav ciab no tau txais los ntawm cov nroj tsuag xibtes hu ua Copernicia prunifera, uas tau loj hlob hauv Brazil. Peb tuaj yeem tau txais cov quav ciab los ntawm kev ntaus cov quav ciab tawm ntawm cov xibtes qhuav, tom qab ntawd los ntawm kev ua kom zoo ntawm cov extract no. Feem ntau, ntshiab carnauba wax yog daj xim.
Feem ntau, carnauba wax muaj li ntawm 80-85% fatty acid esters. Nyob ib ncig ntawm 20% ntawm cov quav ciab yog esterified fatty diols. 10% ntawm cov quav ciab yog methoxylated lossis hydroxylated cinnamic acid. Ntxiv mus, kwv yees li 6% ntawm cov quav ciab muaj hydroxylated fatty acids.
Qhov tseem ceeb tshaj, qhov siv quav ciab no nyuaj dua li pob zeb thiab insoluble hauv dej thiab ethanol. Tsis tas li ntawd, nws muaj qhov siab melting point heev. Txawm li cas los xij, carnauba wax yog non-toxic thiab hypoallergenic. Peb tuaj yeem txhuam cov wax no kom zoo nkauj.
Cov ntawv thov ntawm carnauba siv quav ciab suav nrog kev siv khoom noj, tshuaj pleev ib ce, tsheb, thiab rooj tog zaum, ua pwm rau cov khoom siv semiconductor, ua cov txheej rau cov hniav txhuam hniav, thiab lwm yam. Nyob rau hauv lwm yam lus, hypoallergenic zog thiab siab gloss ua rau nws tseem ceeb raws li ib tug thickener nyob rau hauv cov tshuaj pleev ib ce, xws li lipstick, eyeliner, mascara, qhov muag ntxoov ntxoo, foundation, deodorant, thiab lwm yam.
Txawm li cas los xij, carnauba wax nws tus kheej yog nkig; Yog li ntawd, nws yog feem ntau siv ua ke nrog lwm cov waxes xws li beeswax. Yog li ntawd, peb tuaj yeem siv carnauba wax los kho thiab cov khoom siv tawv tawv. Tsis tas li ntawd, nws muab cov khoom no ua kom zoo nkauj thiab ua kom tawv tawv thiab ua kom ntev.
Qhov txawv ntawm Candelilla Wax thiab Carnauba Wax yog dab tsi?
Candelilla wax thiab carnauba ciab yog cov ntaub ntawv tseem ceeb hauv kev lag luam sib txawv. Qhov sib txawv tseem ceeb ntawm Candelilla wax thiab Carnauba wax yog tias Candelilla wax muaj cov ntsiab lus carbon siab, thaum carnauba ciab muaj cov ntsiab lus qis. Feem ntau, cov ntsiab lus ntawm hydrocarbons hauv Candelilla wax yog kwv yees li 50%, thaum carnauba ciab tsuas muaj li ntawm 3% hydrocarbons.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm Candelilla wax thiab Carnauba wax hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Candelilla Wax vs Carnauba Wax
Candelilla wax yog ib qho khoom siv los ntawm cov nplooj ntawm cov nplooj me me, thaum carnauba wax yog ib hom ntawm cov khoom siv ntuj tsim uas muaj cov roj acid esters, fatty alcohols, acids, thiab hydrocarbons. Qhov sib txawv tseem ceeb ntawm Candelilla wax thiab Carnauba wax yog tias Candelilla wax muaj cov ntsiab lus siab carbon, whereas carnauba wax muaj cov ntsiab lus qis.
