Methyl 4-hydroxybenzoate Methylparaben CAS No.99-76-3
Sharaxaada Alaabta
- Methyl 4-hydroxybenzoate, oo sidoo kale loo yaqaan Methyl Paraben, oo inta badan loo isticmaalo ilaalinta jeermiska disha ee isku-dhafka organic, cuntada, qurxinta, daawada, iyo sidoo kale loo isticmaalo ilaalinta quudinta.
- Methyl 4-hydroxybenzoate waa arrin dabiici ah. Sababtoo ah qaab-dhismeedka phenolic hydroxyl, waxay leedahay sifooyin bakteeriyada ka fiican marka loo eego benzoic acid iyo sorbic acid. Dhaqdhaqaaqa paraben waxaa inta badan sabab u ah xaaladdeeda molecular, iyo kooxda hydroxyl ee ku jirta molecule waa la nadiifiyey oo aan hadda la saarin. Sidaa darteed, waxay saameyn wanaagsan ku leedahay inta u dhaxaysa pH 3 ilaa 8. Waa walax kiimiko ah oo aan firfircoonayn oo ay fududahay in la jaanqaado walxo kiimiko oo kala duwan.
Tilmaamaha Alaabta
- Waxqabadka xasilloon;
- Ma jiri doono burbur ama isbeddel dhaqdhaqaaqa heerkulka sare hoostiisa;
- Si fudud ula jaan qaada walxaha kiimikaad ee kala duwan;
- Isticmaalka dhaqaale iyo muddada dheer.
