Iyini i-Sodium Dehydroacetate CAS 4418-26-2?

I-Sodium dehydroacetate iyimpuphu emhlophe ekristalu encibilika kalula emanzini. Ibonisa i-asidi ebuthakathaka emanzini futhi ingakhipha igesi ye-SO2 ngaphansi kwezimo ze-asidi. I-Sodium dehydroacetate iyisivikelo sokudla esibanzi futhi esilwa namagciwane amaningi, esinamandla okuvimbela isikhunta nemvubelo. Ngesikhathi esifanayo, umphumela wokulwa namagciwane uphakeme izikhathi eziningana noma ngisho namashumi kune-sodium benzoate kanye ne-potassium sorbate esetshenziswa kabanzi. Okubaluleke kakhulu ukuthi ayinawo umphumela omncane wokuvimbela kumagciwane akhiqiza i-asidi, ikakhulukazi amagciwane e-lactic acid.

Isicelo

1. I-Sodium dehydroacetate iyi-ejenti yokulwa namagciwane ephephile kakhulu, ububanzi obukhulu bama-antibacterial, kanye nekhono elinamandla lokulwa namagciwane. Ayithinteki kakhulu yi-acidity noma i-alkalinity yokudla futhi ingagcina ukusebenza okuphezulu kwamagciwane ngaphansi kwezimo ze-acidic noma ze-alkaline kancane. Amandla ayo okulwa namagciwane angcono kune-sodium benzoate, i-potassium sorbate, i-calcium propionate, njll., okwenza kube yi-preservative yokudla efanelekile.
2. I-Sodium dehydroacetate ingasetshenziswa ekwelapheni ubuso bensimbi, ekususeni amafutha, nasekuvimbeleni ukugqwala ezindaweni zensimbi,
3. I-Sodium dehydroacetate ingasetshenziswa futhi ekuhlaziyweni kwamakhemikhali kanye nokulungiswa kwama-mordants.
4. I-Sodium dehydroacetate isetshenziswa futhi emikhakheni yokwenza iphepha, isikhumba, izembozo, izimonyo, njll.
