Incazelo emfushane:

Igama lomkhiqizo: Methylparaben

Inombolo yeCas: 99-76-3

Ukubukeka: I-Crystalline Powder Emhlophe

I-Molecular Formula: C8H8O3

Isisindo se-molecule: 152.15

I-Methyl 4-hydroxybenzoate, eyaziwa nangokuthi i-Methyl Paraben, isetshenziswa kakhulu njengesivikeli esibulalayo esibulalayo sokwakheka kwemvelo, ukudla, izimonyo, umuthi, futhi isetshenziswa futhi njengesilondolozi sokudla.

I-Methyl 4-hydroxybenzoate iyindaba ephilayo. Ngenxa yesakhiwo sayo se-phenolic hydroxyl, inezindawo ezingcono zokulwa namagciwane kune-benzoic acid ne-sorbic acid.

Isingeniso Somkhiqizo

I-Methyl 4-hydroxybenzoate, eyaziwa nangokuthi i-Methyl Paraben, isetshenziswa kakhulu njengesivikeli esibulalayo esibulalayo sokwakheka kwemvelo, ukudla, izimonyo, umuthi, futhi isetshenziswa futhi njengesilondolozi sokudla.

I-Methyl 4-hydroxybenzoate iyindaba ephilayo. Ngenxa yesakhiwo sayo se-phenolic hydroxyl, inezindawo ezingcono zokulwa namagciwane 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

1.Ukusebenza okuzinzile;

2.Ngeke kube khona ukubola noma ushintsho lomsebenzi ngaphansi kwezinga lokushisa eliphezulu;

3.Ihambisana kalula nezinto ezihlukahlukene zamakhemikhali;

4.Ukusetshenziswa kwezomnotho nesikhathi eside.

Izinhlelo zokusebenza

Isetshenziselwa isinqandakuvunda sokugeza amakhemikhali nsuku zonke (uketshezi lokuhlanza, ijeli yokugeza, i-shampoo, okokuhlanza, njll.).

Iphinde isetshenziselwe isinqandakuvunda ekuphakeleni, emikhiqizweni yezimboni yansuku zonke, ukubulawa kwemishini, imboni yendwangu (indwangu, intambo kakotini, i-chemical fiber), njll.
