Sodium Laureth Sulfate (SLES), ua tus "surfactant kub" hauv kev lag luam tshuaj txhua hnub, nws cov kev ua tau zoo thiab tus nqi txiav txim siab ncaj qha los ntawm cov ntsiab lus ntawm nws cov khoom xyaw nquag. Muaj plaub qhov kev sib xyaw tseem ceeb muaj nyob rau hauv kev ua lag luam: 20%, 55%, 60%, thiab 70%, tsim kom muaj qhov sib txawv ntawm tus nqi:
70% Qib huv siab: Cov tshuaj nplaum zoo li gel, yaj sai, muaj cov khoom ua kom tuab, thiab ua rau cov npuas dej zoo thiab ruaj khov. Nws yog cov khoom xyaw tseem ceeb hauv cov tshuaj zawv plaub hau zoo thiab cov khoom saib xyuas menyuam yaus.
60% -55% Qib kev lag luam: Cov kua ua kua, nrog cov khoom tsis huv ntawm kwv yees li 3% -5%, tsim nyog rau cov tshuaj da dej thiab cov tshuaj ntxhua khaub ncaws. Tus nqi qis dua 15% -20% piv rau qib 70%.
20% Qib Diluted: Muaj dej ntau, sodium chloride, thiab lwm yam khoom siv ntxiv, thiab tsuas yog siv tau rau hauv cov khoom qis xws li cov tshuaj tshem roj.
Tsis ntev los no, ntau tus neeg siv khoom tau tshaj tawm tias tau txais cov khoom cuav, nrog rau qhov sib txawv ntawm tus nqi. Aojin Chemical muag cov khoom muaj 70% SLES, uas kim dua tab sis lav qhov zoo! Tus nqi thiab qhov zoo ntawm cov khoom yog sib piv ncaj qha; tsis txhob xav tias yuav yuav70% SLESntawm tus nqi ntawm 55% SLES!
Tam sim no, muaj ib qho xwm txheej ntawm SLES adulteration hauv kev ua lag luam.
Siv cov tshuaj sodium dodecylbenzenesulfonate (LAS) pheej yig los hloov ntau dua 30% ntawm SLES, tag nrho cov surfactant cov ntsiab lus zoo li ua tau raws li tus qauv, tab sis lub peev xwm ua npuas dej txo qis 40%, thiab qhov khaus nce ntxiv 3 zaug. Thaum kuaj los ntawm ob-theem titration, cov ntsiab lus SLES tiag tiag hauv cov khoom zoo li no feem ntau tsawg dua ib nrab ntawm tus nqi tau hais.
Qee cov khoom tsuas yog hais tias "tag nrho cov khoom xyaw nquag ≥30%", txhob txwm zais qhov feem pua ntawm SLES. Cov ntsiab lus SLES tiag tiag tsuas yog 20%!
Thaum yuav SLES, nco ntsoov xaiv lub tuam txhab uas muaj npe nrovSLES 70% chaw tsim khoom. Qhov zoo ntawm cov khoom yuav tsum tau muab tso ua ntej dua li tus nqi. Soj ntsuam qhov zoo ntawm cov khoom ua ntej txiav txim siab tus nqi kom tsis txhob yuav cov khoom cuav. Qhov zoo ntawm cov khoom thiab tus nqi yog sib npaug ncaj qha!
