Qhov sib txawv tseem ceeb ntawm sodium lauryl sulfate thiab sodium laureth sulfate yog tias sodium lauryl sulfate yog khaus ntau dua piv rau sodium laureth sulfate.
Ob leeg sodium lauryl sulfate thiab sodium laureth sulfate yog surfactants. Lawv txo qis qhov nro ntawm cov tshuaj aqueous, yog li, txhim kho cov ntub dej ntawm qhov chaw. Yog li ntawd, lawv muaj txiaj ntsig zoo hauv cov khoom siv tshuaj pleev ib ce xws li xab npum, tshuaj zawv plaub hau, shaving cream, mascara, moisturizer lotions, thiab sun cream. Tsis tas li ntawd, lawv yog cov tshuaj ntxuav tes, tshuaj txhuam hniav, ntaub pua tsev ntxhua khaub ncaws, ntaub nplaum, thiab lwm yam. Nyob rau hauv luv luv, lawv yog ib qho tseem ceeb nyob rau hauv cov khoom no vim lawv muaj peev xwm tshem tawm cov roj thiab roj, kom ua tau zoo foaming agents, thiab pheej yig heev. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm sodium lauryl sulfate thiab sodium laureth sulfate tshwm sim vim sodium laureth sulfate tsis yaj cov proteins hauv cov ntaub so ntswg xws li Sodium lauryl sulfate.
Sodium Lauryl Sulfate yog dab tsi?
Sodium lauryl sulfate lossis SLS muaj ntau lub ntsiab lus, xws li sodium dodecyl sulfate (SDS), lauryl sodium sulfate, lauryl sulfate sodium ntsev, sodium N- dodecyl sulfate, thiab lwm yam. Cov qauv qauv ntawm cov tshuaj no yog CH 3-(CH2)11-O-SO3 -Na+ Nws yog qhov nrov ua tus neeg saib xyuas zoo, yog li, suav nrog ntau yam khoom siv tu thiab cov khoom siv hauv chav dej uas peb siv. Txawm li cas los xij, cov kev sim kuaj tau ua pov thawj tias SLS yog cov tawv nqaij khaus. Nws ua rau muaj kev puas tsuaj loj rau cov tawv nqaij ib txwm los ntawm kev cuam tshuam nws qhov sib npaug ntawm ntuj. Yog li ntawd, daim tawv nqaij ua permeable rau lwm yam tshuaj. Cov tawv nqaij rhiab heev yog qhov yooj yim tshaj plaws los ntawm SLS, thiab siv sij hawm ntev tuaj yeem ua rau khaus, tawv nqaij qhuav. Tsis tas li ntawd, nws yuav muaj tshuaj lom yog tias nkag mus rau hauv qhov ncauj.
Daim duab 01: Sodium Lauryl Sulfate
Tsis tas li, sodium lauryl sulfate ua rau qhov muag khaus ib yam nkaus. Vim yog cov tawv nqaij khaus, tib neeg tsis txhob siv cov khoom siv nrog sodium lauryl sulfate. Yog li, sodium laureth sulfate tau hloov cov tshuaj no. Cov tshuaj zawv plaub hau nrog SLS tuaj yeem ua rau cov plaub hau poob, thiab nws ua rau cov plaub hau nyias. Siv cov tshuaj txhuam hniav nrog SLS ua rau lub qhov ncauj rwj. Txawm li cas los xij, SLS tsis yog carcinogenic. Tab sis, nws tuaj yeem cuam tshuam nrog lwm cov tshuaj hauv cov khoom siv tshuaj pleev ib ce los tsim nitrosamines uas yog carcinogenic.
Sodium lauryl sulfate kuj yog ib qho emulsifying thiab dispersing tus neeg sawv cev. Vim nws lub peev xwm emulsifying thiab thickening, peb tuaj yeem siv nws ua khoom noj khoom haus. Tsis tas li ntawd, nws yog ib qho tseem ceeb nyob rau hauv lub chaw soj nstuam rau kev npaj nanoparticle thiab rau cov protein sib cais los ntawm electrophoresis (SDS-PAGE txheej txheem).
Sodium Laureth Sulfate yog dab tsi?
Cov mis mos molecular ntawm sodium laureth sulfate yog CH3-(CH2)10-CH2 -(OCH2CH2)n-O-SO 3Na+ It is popular as SLES in short form. Tsis tas li ntawd, qhov no kuj yog ib qho surfactant thiab, yog li ntawd, muaj txiaj ntsig zoo rau tib lub hom phiaj xws li sodium lauryl sulfate. Txawm li cas los xij, Sodium Laureth Sulfate yog qhov khaus tsawg dua SLS.
Daim duab 02: Cov qauv tshuaj ntawm Sodium Laureth Sulfate
Yog li, cov tuam txhab siv SLES nquag siv cov khoom siv tawv nqaij thiab plaub hau dua li SLS. Sodium Laureth Sulfate tsis yog carcinogenic. Txawm li cas los xij, thaum nws kis tau nrog qee yam tshuaj xws li ethylene oxide lossis 1, 4- dioxane nws tuaj yeem ua carcinogenic.
Qhov txawv ntawm Sodium Lauryl Sulfate thiab Sodium Laureth Sulfate yog dab tsi?
Sodium lauryl sulfate yog cov organic compound uas muaj cov tshuaj CH3-(CH2)11 -O-SO3-Na+ Sodium laureth sulfate kuj yog cov organic compound tab sis, muaj cov tshuaj formula CH 3-(CH2)10-CH2-(OCH 2CH2)n-O-SO3 Na+ Qhov sib txawv tseem ceeb ntawm sodium lauryl sulfate thiab sodium laureth sulfate yog tias sodium lauryl sulfate yog khaus ntau dua piv rau sodium laureth sulfate. Yog li ntawd, kom tsis txhob muaj cov tawv nqaij khaus, sodium lauryl sulfate hauv cov khoom siv tawv nqaij tau raug hloov los ntawm sodium laureth sulfate. Tsis tas li ntawd, raws li lwm qhov sib txawv tseem ceeb ntawm sodium lauryl sulfate thiab sodium laureth sulfate, peb tuaj yeem hais tias sodium lauryl sulfate tuaj yeem yaj cov protein hauv cov ntaub so ntswg thaum sodium laureth sulfate tsis. Qhov no yog vim li cas rau qhov sib txawv tseem ceeb ntawm sodium lauryl sulfate thiab sodium laureth sulfate.
Txawm li cas los xij, muaj ntau yam kev siv sodium lauryl sulfate xws li tus neeg saib xyuas zoo, emulsifying thiab dispersing tus neeg sawv cev, rau nano particle npaj thiab rau cov protein sib cais los ntawm electrophoresis whereas peb siv tau sodium laureth sulfate ua ib feem ntawm daim tawv nqaij. thiab cov khoom siv plaub hau, ua surfactant, thiab lwm yam.
Summary – Sodium Lauryl Sulfate vs Sodium Laureth Sulfate
Qhov sib txawv tseem ceeb ntawm sodium lauryl sulfate thiab sodium laureth sulfate yog tias sodium lauryl sulfate yog khaus ntau dua piv rau sodium laureth sulfate. Yog li cov tuam txhab lag luam nyiam siv sodium laureth sulfate es tsis yog sodium lauryl sulfate hauv cov khoom tu tawv nqaij kom tsis txhob muaj tawv nqaij khaus.
