Factory Supply CAS 99-76-3 Methylparaben Pure Methylparaben Powder
Product Description
Methylparaben, chinhu cheorganic chine fomula C8H8O3, white crystalline poda kana crystal isina ruvara, inonyungudika mudoro, ether, yakanyanya kunyungudika mumvura, inofashaira 270-280 °C. Inonyanya kushandiswa se bactericidal preservative ye organic synthesis, chikafu, cosmetics uye mushonga, uye inoshandiswawo sechikafu chekuchengetedza. Nekuti ine phenolic hydroxyl chimiro, antibacterial maitiro ayo akasimba kupfuura benzoic acid uye sorbic acid. Maitiro ayo ekuita ndeye: kuparadza sero membrane yezvipembenene, denature mapuroteni mumasero, uye inhibit basa rekufema ma enzymes uye ma electron ekufambisa ma enzymes e microbial masero.

Function
Methylparaben poda ine mabasa akasiyana siyana, anosanganisira:
Sterilization uye antiseptic : Methylparaben ine yakasimba antibacterial uye bactericidal effect, inogona kuparadza sero membrane yezvipembenene, denaturate protein iri muchitokisi, uye inhibit basa rekufema enzyme system uye electron transfer enzyme system ye microbial cells, kuitira kuti iite basa rekuita sterilization uye antiseptic. Ichi chivakwa chinoita kuti chishandiswe zvakanyanya sekuchengetedza chikafu, cosmetics, mushonga uye mamwe minda.
Anti-inflammatory uye antibacterial : Pamusoro pekuchengetedza, Methylparaben zvakare ine anti-kuzvimba uye antibacterial mhedzisiro uye inogona kushandiswa kurapa fungal hutachiona hweganda, senge kukwenya kweganda, kuputika kweganda uye zvimwe zvisingafadzi zviratidzo. Mukushandisa zvine mwero, methyl p-hydroxybenzoate ine mamwe maitiro ekurapa paganda.
For organic synthesis : Methylparaben inogona kushandiswa seyakagadzirwa organic synthesis, kunyanya esters ayo, akadai semethyl paraben, ethyl paraben, etc. Aya ester anogona kushandiswa sekuwedzera kwechikafu, senge soy muto, vhiniga, zvinwiwa zvinotonhorera, michero yekunhuhwirira, michero nemiriwo, mapreservatives ezvigadzirwa zvema pickled.
Kushanda mumishonga uye zvizoro : Methylparaben inoshandiswa sekuchengetedza mumishonga uye zvizoro kudzivirira chikafu kubva pakuora kana mushonga kubva pakuipa. Muzvizoro, inogona kudzivirira zvizorwa kubva pakuparara, kuora, uye kuchengetedza kutsva uye kushanda kwezvigadzirwa.
Zvimwe zvinoshandiswa : Methylparaben inoshandiswawo seyepakati mudhayi, mishonga yezvipembenene, uye mumishonga yezvipembenene yekugadzira organophosphorus mishonga yezvipembenene. Pamusoro pezvo, inoshandiswa mukugadzira mvura yecrystal polymers nemapurasitiki, uye sephenol derivative yebenzoic acid, inogona kuvharisa huwandu hwakawanda hwegiremu-positive mabhakitiriya uye mamwe mabhakitiriya egiremu-negative 4.
Mukupfupisa, Methylparaben poda haisi kungoshanda chete kuchengetedza uye antibacterial agent, asiwo inoita basa rinokosha mukugadzirwa kwehupenyu uye mamwe minda.
Application
Methylparaben, inozivikanwawo semethyl paraben kana methyl hydroxyphenyl ester, iwhite crystalline poda kana kristaro isina ruvara, inonyungudika mudoro, ether uye acetone, inonyungudika zvishoma mumidziyo yemvura, kubikira kwe270-280 ° C. Kunyanya kushandiswa kwechiumbwa ichi kunosanganisira:
Organic synthesis : Seyakakosha zvinhu zveorganic synthesis, inoshandiswa kugadzira akasiyana makemikari.
chiwedzero chechikafu : chinoshandiswa semushonga wekuchengetedza utachiona kudzivirira chikafu kuti chisakara uye kuwedzera hupenyu hwesherufu yechikafu.
Cosmetics : Se bactericidal inochengetedza zvizoro, chengetedza hutsanana uye mhando yezvizoro.
Pharmaceutical : methyl p-hydroxybenzoate inoshandiswa semushonga unochengetedza muindasitiri yemishonga kuti uve nechokwadi chekuchengetedzwa uye kushanda kwemishonga.
Feed preservative : inoshandiswa mukudyisa kudzivirira kukura kwehutachiona uye kuve nechokwadi chemhando uye kuchengetedzeka kwechikafu.
Pamusoro pezvo, methyl p-hydroxybenzoate inewo phenolic hydroxyl boka chimiro, saka mashandiro ayo antibacterial akasimba kupfuura benzoic acid uye sorbate, inogona kuparadza cell membrane yezvipembenene, mapuroteni edenature mumaseru, uye inhibisa mashandiro eiyo enzyme yekufema system uye elektroni yekufambisa enzyme system yehutachiona hwehutachiona, kuitira kuzadzisa chinangwa cheiyo anti-corrosion. Mushonga uyu unoshandiswa zvakanyanya muminda yakawanda uye yakakosha kemikari raw material.
