Cov khoom xyaw ntuj, yog tias koj ua cov khoom kom zoo nkauj tawm ntawm lawv, tsis txhob lather, tsis ua npuas ncauj, tsis zoo ntxuav tawm, xyaum tsis tshem cov av thiab roj. Qhov no yog dab tsi surfactants siv rau hauv tshuaj thiab tshuaj pleev ib ce industries.
Ntxiv rau, surfactants yog tsim nyog raumake-up removers thiab daim tawv nqaij cream tsis zom rau hauv dej thiab roj thaum lub sij hawm cia. Nws yuav zoo li yog dab tsi txaus ntshai nyob rau hauv xws li ib tug lwj mus rau hauv ob theem? Qhov tseeb yog tias cov kab mob tsis zoo rau lub dermis tuaj yeem tsim rau ntawm cov roj.
Yav dhau los, surfactants, ua ntej kev lag luam tshuaj lom neeg, hloov tsiaj rog, tab sis siv lawv tsis yog ib puag ncig thiab tib neeg. Thawj surfactants tsim los ntawm cov kws tshuaj tsis yog maj thiab txhoj puab heev ntawm lawv cov nyhuv ntawm daim tawv nqaij.
Tom qab tag nrho, cov tshuaj no yog dab tsi? Lawv ua rau daim tawv nqaij soapy, tsim ua npuas ncauj. Yog tias koj khawb tob dua, txheej txheej saum toj kawg nkaus ntawm lub dermis nyob rau hauv kev cuam tshuam ntawm surfactants qhib, thiab cov khoom xyaw tseem ceeb ntawm cov tshuaj zawv plaub hau lossis qab zib muaj peev xwm nkag mus rau ntawm daim tawv nqaij.
Dab tsi yog qhov teeb meem tseem ceeb ntawm surfactants yog tias lawv tuaj yeem nkag mus rau ntawm daim tawv nqaij nrog rau cov tshuaj nquag, thiab nrog rau cov av lossis cov rog tsis tsim nyog, tshem cov rog ntawm daim tawv nqaij uas xav tau. Yog li ntawd, qhov saum npoo ntawm daim tawv nqaij yuav qhuav, khaus, pob khaus lossis liab yuav tshwm sim.
Dab tsi yog qhov phom sij ntawm kev siv cov khoom hnyav hnyav?
Peb tau los ze rau qhov teeb meem ntawm kev phom sij ntawm surfactants. Qhov no puas muaj tseeb los yog lus dab neeg? Qee lub sij hawm peb liam tias kev noj zaub mov tsis zoo, tsis tsaug zog, tsis muaj cov vitamins rau cov tsos mob ntawm pob txuv, pob txuv, tawv nqaij qhuav thiab tsis muaj sia, cov plaub hau nkig. Txawm li cas los xij, qhov teeb meem yuav tsum tau saib los ntawm txhua sab. Peb siv dab tsi thaum cov txheej txheem tu cev txhua hnub tuaj yeem dhau los ua "kev phem".
Peb daim tawv nqaij yog qhov nqus dej thoob plaws txhua yam ntawm nwssiv. Ua ntej siv cov khoom siv da dej uas pheej yig, cov nplaum nplaum lossis cov tshuaj pleev ib ce, xav txog tias cov khoom xyaw nquag ntawm cov khoom no yuav nkag mus rau ntawm daim tawv nqaij thiab nkag mus rau hauv cov hlab ntsha. Tias yog vim li cas nws thiaj li tseem ceeb heev rau kev siv cov tshuaj pleev ib ce organic, xyuam xim rau cov hnub tas sij hawm thiab, tau kawg, sim tsis txhob siv cov khoom nrog cov khoom xyaw hnyav.
Qhov txawv ntawm surfactants
Chemists faib cov surfactants ua plaub pawg raws li lawv ua haujlwm ntawm daim tawv nqaij, lawv lathe li cas, thiab lawv tshem tawm cov av hauv dej li cas.
- Anionic. Xws li surfactants yog cov feem ntau, vim tias lawv muaj peev xwm ntxuav cov roj thiab cov av, txawm tias cov dej nyuaj. Ib qho ntawm feem ntau siv yog sodium lauryl sulfate. Tsis ntev los no tau muaj kev hloov pauv mus rau kev siv softer thiab tsawg ziab surfactants hauv kev lag luam. Lauryl glucoside tsuas yog hais txog anionic surfactants xwb.
- Cationic - cov tshuaj nquag no ntxuav cov av phem dua li cov anionic, thiab tib lub sijhawm lawv tuaj yeem ua mob rau daim tawv nqaij ntau dua. Cationic surfactants yog siv me me los ua cov tshuaj zawv plaub hau, tab sis lawv nquag siv hauv cov tshuaj pleev ib ce kom tshem tawm cov hluav taws xob zoo li qub ntawm khaub ncaws lossis plaub hau.
- Amphoteric. Lawv feem ntau yog siv ua ke nrog anionic sawv daws yuav kom txo tau qhov tsis zoo ntawm cov tom kawg ntawm lub dermis. Lawv txhim kho cov foaming ntawm cov tshuaj pleev ib ce.
- Non-ionic active tshuaj me ntsis irritate ntawm daim tawv nqaij, muab softness. Xws li surfactants feem ntau yog siv ua ke nrog anionic,Piv txwv li hauv cov tshuaj zawv plaub hau thiab cov tshuaj pleev kom ua rau cov plaub hau silky thiab mos.
Dispel the myths about harmfulness of surfactants
Rau ntau tshaj li ib nrab xyoo pua, tib neeg tau siv cov khoom siv tu cev thiab tshuaj pleev ib ce. Nws yuav tsum tau muab sau tseg tias yav dhau los cationic nyuaj thiab anionic sawv daws yuav siv ntau nyob rau hauv cov tshuaj lom neeg kev lag luam, tab sis tam sim no muaj ib tug preponderance rau kev siv cov active tshuaj nrog ib tug me me txoj kev ntawm kev ua.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias txawm li cas los xij koj siv cov khoom lag luam twg (lub ntsiab lus tshuaj zawv plaub hau, gel da dej, xab npum huv), koj cov plaub hau yuav tsis poob thiab koj cov tawv nqaij yuav tsis tev tawm. Qhov kev puas tsuaj los ntawm kev siv cov surfactants yog exaggerated ntau.
Feem ntau ntawm qhov no hais txog mus rau sodium lauryl sulfate, cov surfactant no muaj lub koob npe phem heev. Pom cov khoom xyaw no hauv tshuaj zawv plaub hau, cov poj niam niaj hnub thiab cov ntxhais, tau nyeem cov ntawv hais txog qhov txaus ntshai ntawm sulfates hauv cov tshuaj pleev ib ce, npaj txhij muab pov rau hauv lub thoob khib nyiab.
Txawm li cas los xij, qhov kev ntes yog tias cov plaub hau, uas tom qab siv tshuaj zawv plaub hau lossis tshuaj zawv plaub hau yuav tsum ci thiab voluminous, yuav tsis ciaj sia, vim nws twb muaj cov cell keratinized tuag lawm. Txiav txim rau koj tus kheej, yog cov plaub hau lossis cov rau tes tseem ciaj sia, ces txoj kev txiav cov plaub hau los yog rau tes yuav raug tsim txom.
Nws hloov tawm tias cov plaub hau tuaj yeem ua silky thiab "nyob" tsuas yog tias nws ntxuav cov av lossis roj. Qhov ntau foaming tshuaj zawv plaub hau muaj, qhov zoo nkauj dua thiabcov plaub hau huv yuav saib zoo dua.
Lwm nqe lus nug: "Puas muaj surfactants muaj sulfates tiag tiag ua rau lub dermis?" Nws tau raug pov thawj hauv kev kho mob tias lawv yuav ua rau cov tawv nqaij puas tsuaj tiag tiag yog tias kev sib cuam tshuam ntev li ib teev. Koj puas xav tias koj tuaj yeem ntub koj cov plaub hau hauv tshuaj zawv plaub hau rau ntau tshaj ib teev? Tsis tas li ntawd, kev nqus pa ntawm surfactants ntau ntau hauv daim ntawv ntshiab yuav ua teeb meem.
Nws hloov tawm tias koj yuav tsum tsis txhob tso siab ntau cov ntawv uas rov ua dua ib qho tom qab lwm cov ntaub ntawv tsis tau lees paub txog kev phom sij ntawm PAS. Yog tias koj txaus siab rau lub ntsiab lus no, ces kawm kom ntxaws los yog siv cov tshuaj pleev ib ce kom zoo.
Yuav ua li cas lauryl glucoside ua
Dab tsi yog "surfactant", peb xam nws tawm. Lawv tuaj yeem ua rau muaj kev phom sij lossis tsis muaj kev ua xua lossis lwm yam khoom tsis zoo.
Surfactants yog tsim los ntawm kws tshuaj los ntawm peb hom raw khoom. Thawj txoj hauv kev kom tau txais lawv yog siv cov khoom xyaw ntuj - cov rog thiab roj. Txoj kev thib ob ntawm kev tsim khoom yog kev siv roj. Qhov thib peb txoj hauv kev kom tau txais surfactants yog synthesis, uas yog, cov khoom tsim khoom tsim tawm hauv chav kuaj los ntawm ntau yam khoom ntawm lub hauv paus chiv keeb thiab tsim. Lauryl glucoside, uas tau tham hauv tsab xov xwm no, belongs rau thawj pab pawg ntawm surfactants raws li kev npaj. Nws yuav tsum tau piav qhia ntau ntxiv.
Cia peb saib seb lauryl glucoside yog tsim los li cas, nws tsim kev puas tsuaj thiab cov txiaj ntsig zoo rau daim tawv nqaij, seb puas tuaj yeem ntshai siv cov tshuaj pleev ib ce uas muaj nws.
