Qhov sib txawv tseem ceeb ntawm methyl paraben thiab sodium methylparaben yog tias methylparaben yog cov khoom noj muaj txiaj ntsig zoo rau cov khoom noj, thaum sodium methylparaben yog sodium ntsev ntawm methyl paraben.
Methyl paraben yog cov organic compound uas muaj cov tshuaj CH 3(C6H4 (OH)COO). Sodium methylparaben yog cov organic compound uas muaj cov tshuaj formula Na(CH3(C6H4COO) O). Ob qho tshuaj no tseem ceeb xws li cov khoom noj ntxiv, thiab lawv muaj E tus lej E218 thiab E219, raws li.
YMethyl Paraben yog dab tsi?
Methyl paraben yog cov organic compound uas muaj cov tshuaj CH 3(C6H4 (OH)COO). Nws yog ib qho tseem ceeb raws li ib tug preservative thiab yog methyl ester ntawm p-hydroxybenzoic acid. Cov khoom no zoo li tsis muaj xim tsis muaj kob lossis dawb crystalline hmoov. Lawm, nws tshwm sim raws li ib feem ntawm poj huab tais mandibular pheromone. Yog li ntawd, nws tuaj yeem ua pheromone rau ntau yam kab sib txawv. Ntxiv mus, qhov no yog pheromone uas tsim nyob rau hauv hma thaum lub sij hawm estrus, uas yog txuam nrog tus cwj pwm ntawm alpha txiv neej hma. Nws tiv thaiv lwm tus txiv neej los ntawm mounting poj niam nyob rau hauv tshav kub.
Daim duab 01: Cov Qauv Tshuaj ntawm Methyl Paraben
Ntau zaus, methylparaben yog siv los ua cov tshuaj tua kab mob hauv cov khoom siv tshuaj pleev ib ce thiab kev tu tus kheej. Ntxiv mus, peb tuaj yeem siv nws ua zaub mov noj nrog tus lej E E218. Tsis tas li ntawd, cov tshuaj no muaj txiaj ntsig zoo li fungicide rau Drosophila zaub mov xov xwm. Methylparaben yog tshuaj lom rau Drosophila ntawm qhov siab. Nws tuaj yeem ua rau cov nyhuv estrogenic thiab tuaj yeem ua rau qeeb ntawm kev loj hlob ntawm cov menyuam yaus thiab cov menyuam yaus theem.
Feem ntau, methyparaben yog nkag tau yooj yim los ntawm txoj hnyuv los yog los ntawm daim tawv nqaij. Tom qab ntawd, nws nkag mus rau hydrolysis rau p-hydroxybenzoic acid thiab kuj tau tawm sai sai los ntawm cov zis. Yog li ntawd, nws tsis nyob rau hauv lub cev. Raws li kev tshawb fawb toxicity, methylparaben yog xyaum tsis muaj tshuaj lom los ntawm ob qho tib si qhov ncauj thiab parenteral tswj hauv tsiaj.
Sodium Methylparaben yog dab tsi?
Sodium methylparaben yog cov organic compound uas muaj cov tshuaj formula Na(CH3(C6H4 COO)O). Nws tseem muaj npe hu ua sodium methyl para-hydroxybenzoate. Peb tuaj yeem categorize nws li sodium ntsev ntawm methylparaben.
Daim duab 02: Cov Qauv Tshuaj ntawm Sodium Methylparaben
Cov tshuaj no muaj txiaj ntsig zoo li cov khoom noj ntxiv uas muaj tus lej E E219. Nws yog ntxiv rau cov khoom noj ua ib tus neeg saib xyuas.
Dab tsi yog qhov zoo sib xws ntawm Methyl Paraben thiab Sodium Methylparaben?
- Methyl Paraben thiab Sodium Methylparaben yog qhov tseem ceeb hauv kev lag luam khoom noj.
- ob leeg muaj peev xwm khaws cov khoom noj.
