I-Methyl 4-hydroxybenzoate Methylparaben CAS No.99-76-3
Incazelo Yemikhiqizo
- I-Methyl 4-hydroxybenzoate, eyaziwa nangokuthi i-Methyl Paraben, isetshenziswa kakhulu njengesivimbeli sokunqanda ukubola kwe-organic synthesis, ukudla, izimonyo, umuthi, futhi isetshenziswa futhi njengesilondolozi sokudla.
- I-Methyl 4-hydroxybenzoate iyindaba ephilayo. Ngenxa yesakhiwo sayo se-phenolic hydroxyl, inezindawo zokulwa namagciwane ezingcono kune-benzoic acid ne-sorbic acid. Umsebenzi we-paraben ungenxa yesimo sawo samangqamuzana, futhi iqembu le-hydroxyl ku-molecule liye laqiniswa futhi alisekho i-ionized. Ngakho-ke, inomphumela omuhle ebangeni le-pH 3 kuya ku-8. Kuyinto engasebenzi ngamakhemikhali futhi kulula ukuhambisana nezinto ezihlukahlukene zamakhemikhali.
Isici soMkhiqizo
- Ukusebenza okuzinzile;
- Ngeke kube khona ukubola noma ukuguqulwa komsebenzi ngaphansi kwezinga lokushisa eliphezulu;
- Ihambisana kalula nezinto ezihlukahlukene zamakhemikhali;
- Ukusetshenziswa kwezomnotho nesikhathi eside.
Ukuhlaziya Okuyisisekelo
| Izinto | Ukucaciswa |
| Ukubukeka | I-crystalline powder emhlophe |
| Okuqukethwe kwe-AI (%) | 99.0-100.0 |
| Iphoyinti lokuncibilika (℃) | 125-128 |
| I-Acidity (pH) | 4.0-7.0 |
| Izinsalela zokubasa (%) | Ubukhulu 0.1 |
Izinhlelo zokusebenza
- Isetshenziselwa isinqandakuvunda sokugeza amakhemikhali nsuku zonke (uketshezi lokuhlanza izingubo, ijeli yokugeza, i-shampoo, okokuhlanza, njll.).
- Iphinde isetshenziselwe isinqandakuvunda ekuphakeleni, emikhiqizweni yezimboni yansuku zonke, ukubulawa kwamagciwane kwemishini, imboni yendwangu (indwangu, intambo kakotini, i-chemical fiber), njll.
