Lecithin thiabhydrogenated lecithinyog ob qho tib si siv rau hauv cov khoom siv tawv nqaij ua emulsifiers thiab moisturizers.Lecithin, tseem hu ua qe qe, yog ib qho sib xyaw ntawm cov xim daj xim av oily tshuaj muaj nyob rau hauv cov tsiaj thiab cov ntaub so ntswg, nrog rau cov qe qe. Nws cov khoom muaj xws li phosphate, choline, fatty acids, glycerol, glycolipids, triglycerides, thiab phospholipids.
Txawm li cas los xij, muaj qee qhov sib txawv ntawm ob:
1. Lecithin yog ib yam khoom ntuj tsim los ntawm cov taum pauv, qe, lossis noob paj noob hlis, thaum hydrogenated lecithin yog tsim los ntawm cov txheej txheem tshuaj uas cov roj zaub tau kho nrog hydrogen.
2. Lecithin yog Phosphatidylcholine, ib hom lipid uas yog ib qho tseem ceeb ntawm cov cell membranes hauv tib neeg lub cev. Nws muaj cov ntsiab lus siab ntawm polyunsaturated fatty acids, feem ntau yog phosphatidic acid thiab phosphatidyl ethanolamine, uas muaj antioxidant zog. Hydrogenated lecithin tsis tshua muaj txiaj ntsig rau daim tawv nqaij vim nws muaj cov rog trans, uas tuaj yeem txhaws qhov pores thiab ua rau mob.
3. Lecithin yog ib qho zoo emollient uas pab kom cov tawv nqaij moisturized thiab hydrated. Nws kuj tseem siv rau hauv cov khoom siv los tiv thaiv kev laus vim nws tuaj yeem pab txhim kho daim tawv nqaij zoo nkauj thiab txo cov kab zoo thiab wrinkles. Hydrogenated lecithin ua ib qho surfactant nyob rau hauv cov khoom tu tawv nqaij, pab sib tov cov roj thiab dej-raws li cov khoom xyaw ua ke thiab ua kom cov khoom ruaj khov.
4. Thaum lecithin feem ntau suav hais tias muaj kev nyab xeeb rau txhua hom tawv nqaij, hydrogenated lecithin tuaj yeem ua rau tawv nqaij khaus thiab tej zaum yuav tsis haum rau cov tawv nqaij rhiab heev. Hydrogenated lecithin kuj tseem muaj qis dua HLB tus nqi (Hydrophile-Lipophile Balance) uas txhais tau hais tias nws tsis yog dej-soluble li lecithin thiab tej zaum yuav tsis zoo nyob rau hauv ib co formulations.
Hydrogenated lecithin yog siv nyob rau hauv cov qauv rau cov tshuaj pleev ib ce thiab cov khoom tu tus kheej. Raws li ib tug moisturizer, nws muaj peev xwm mus soften thiab soothe ntawm daim tawv nqaij. Nws txhim kho cov tsos ntawm cov tawv nqaij qhuav los yog puas los ntawm kev txo tev thiab rov ua kom softness. Nws kuj tseem tuaj yeem ua tus emulsifier zoo heev los sib tov dej thiab roj, dispersing roj droplets hauv dej (thiab vice versa).
Emulsifier - khaws cov dej thiab roj sib xyaw ua ke los tsim cov tshuaj pleev ib ce.
Surfactant - txo qhov nro saum npoo, tso cai rau cov sib tov sib xyaw. Emulsifier yog ib qho tshwj xeeb surfactant uas tuaj yeem sib tov ob cov kua sib npaug.
Hydrogenated lecithin yog ib yam khoom ntawm kev tswj hydrogenation ntawm lecithin. Lecithin yog ib txwm tshwm sim sib xyaw ntawm stearic acid, palmitic acid, thiab oleic acid diglycol ester, muaj feem xyuam rau choline ester ntawm phosphate, thiab nws daim ntawv muaj xws li los ntawm cov khoom siv quav ciab mus rau cov kua nplaum, toppedable kua. Lecithin yog ib txwm muaj nyob rau hauv tag nrho cov kab mob nyob thiab yog lub ntsiab ntawm cov paj hlwb. Nws tseem tuaj yeem raug xaiv los ntawm cov taum pauv, mis nyuj, dej hiav txwv, rapeseed, paj rwb, thiab paj noob hlis.
Daim ntawv thov ntawm lecithin nyob rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej yog yav tas los txwv vim nws oxidizing thiab tshav kub-resistant zog. Qhov no yog vim li cas rau kev tsim cov hydrogenated lecithin. Hydrogenated lecithin muaj tag nrho cov txiaj ntsig ntawm ntuj lecithin, tab sis nws txoj kev ruaj ntseg zoo heev.
Lub luag haujlwm tseem ceeb ntawm hydrogenated lecithin hauv cov tshuaj pleev ib ce thiab cov khoom tu tawv nqaij yog humectant, emulsifier thiab antioxidant. Qhov kev pheej hmoo coefficient yog 2, uas muaj kev nyab xeeb thiab siv tau zoo. Nws feem ntau tsis muaj kev cuam tshuam rau cov poj niam cev xeeb tub, thiab hydrogenated lecithin tsis muaj pob txuv ua khoom.
Hauv kev xaus, thaum ob qho tib si lecithin thiab hydrogenated lecithin tuaj yeem siv rau hauv cov khoom tu tawv nqaij ua emulsifiers thiab moisturizers, lecithin yog qhov kev xaiv zoo tshaj vim nws lub hauv paus chiv keeb, cov ntsiab lus siab ntawm cov lipids zoo, thiab zoo sib xws nrog daim tawv nqaij.
Hydrogenated lecithin yog ib feem ntawm hydrolyzed cov khoom ntawm lecithin, uas txhim kho nws cov hydrophilicity. Nws yog absorbed los ntawm tib neeg cov tawv nqaij thiab plaub hau thiab tuaj yeem txhawb kev nkag mus ntawm lwm cov as-ham. Nws yog feem ntau siv rau hauv cov tshuaj pleev ib ce ua ke nrog linolenic acid, hyaluronic acid thiab vitamins. Lecithin muaj zog emulsifying nyhuv thiab muaj peev xwm stabilize lub emulsion. Nws yog qhov tsim nyog rau kev npaj cov khoom siv gel.
Cov yam ntxwv ntawm tsob ntoo: Soybean lecithin yog ib qho tseem ceeb ntawm lub neej. Nws tsis yog tsuas yog ib qho tseem ceeb ntawm tib neeg lub cev biofilm, tab sis kuj yog ib qhov chaw ntawm choline thiab fatty acids. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj hwm lub cev kev ua haujlwm ntawm biofilm thiab cov metabolism hauv lub cev, thiab hu ua "ntshav huv".
Nyob rau tib lub sijhawm, lecithin kuj yog ib qho khoom noj khoom haus zoo uas feem ntau ntxiv. Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv thiab txhim kho cov kab mob plawv thiab paj hlwb, txhim kho lub hlwb kev noj qab haus huv, tiv thaiv lub siab rog thiab cirrhosis, thiab ua kom zoo nkauj ntawm daim tawv nqaij.
Nyob zoo,
