Sodium Dehydroacetate CAS 4418-26-2 ni iki?

Sodium dehydroacetate ni ifu yera ya kristaline yera cyane mu mazi. Yerekana aside irike mumazi kandi irashobora kurekura gaze ya SO2 mugihe cya acide. Sodium dehydroacetate ni uburyo bwagutse kandi bwangiza ibiryo bya antibacterial cyane, bifite imbaraga zikomeye zo kubuza kurwanya umusemburo n'umusemburo. Ku kigero kimwe, ingaruka za antibacterial ni inshuro nyinshi cyangwa inshuro icumi kurenza sodium benzoate ikoreshwa cyane na sorbate ya potasiyumu. Igifite agaciro cyane ni uko idafite ingaruka nke zo guhagarika aside itanga bacteri, cyane cyane bagiteri ya acide lactique.

Gusaba

1.Sodium dehydroacetate ni antibacterial agent ifite umutekano mwinshi, intera nini ya antibacterial, hamwe nubushobozi bukomeye bwa antibacterial. Ntabwo yibasiwe cyane na acide cyangwa alkaline yibiribwa kandi irashobora gukomeza gukora antibacterial nyinshi mugihe acide cyangwa alkaline nkeya. Ubushobozi bwa antibacterial busumba sodium benzoate, potasiyumu sorbate, calcium propionate, nibindi, bigatuma ibika ibiryo byiza.
2. Sodium dehydroacetate irashobora gukoreshwa mugutunganya ibyuma hejuru, kwangirika, no kwirinda ingese hejuru yicyuma,
3. Sodium dehydroacetate irashobora kandi gukoreshwa mugusesengura imiti no gutegura mordants.
4.Sodium dehydroacetate nayo ikoreshwa mubijyanye no gukora impapuro, uruhu, impuzu, kwisiga, nibindi
