EDTA-2Na disodium salt white crystalline powder CAS 139-33-3

Peb tus thawj tswj xyuas kev yuav khoom tau hu rau kuv lub quarter dhau los nrog tib lo lus nug: "Peb xav tau tus neeg sawv cev chelating txhim khu kev qha rau peb cov qauv kev tu tawv nqaij- qib twg ntawmEDTA-2 Na (CAS 139-33-3)Peb yuav tsum qhia meej, thiab peb yuav ntsuas cov neeg siv khoom li cas? "Cov lus nug ncaj ncees. Nrog rau lub ntiaj teb EDTA kev ua lag luam kwv yees kom ncav cuag USD 456.7 lab los ntawm 2030, kev sib tw ntawm cov tuam txhab tau nce zuj zus, thiab cov kev hloov pauv tau zoo tau dhau los ua kom pom tseeb.

Ethylenediaminetetraacetic acid disodium ntsev (EDTA-2Na)yog ib tug hexadentate chelating tus neeg saib xyuas uas tsim tshwj xeeb ruaj khov complexes nrog hlau ions xws li calcium, magnesium, hlau, thiab zinc. Raws li covPubChem database, cov hmoov dawb crystalline no (molecular mis: C₁₀H₁₄N₂Na₂O₈) ua cov pob txha pob txha hauv ntau txhiab daim ntawv thov kev lag luam thiab kev saib xyuas tus kheej thoob ntiaj teb.

EDTA-2Na yog dab tsi thiab nws ua haujlwm li cas?

Thaum cov neeg tsim khoom ntsib cov xim tsis zoo hauv lawv cov khoom lossis cov kev xav tsis txaus ntseeg thaum lub sijhawm tsim khoom, tus neeg ua txhaum feem ntau taug qab cov kab mob hlau. Hlau tsuas yog 0.5 ppm tuaj yeem ua rau cov tshuaj tiv thaiv oxidation uas degrade cov khoom xyaw hauv lub lis piam.

EDTA-2Na ua haujlwm los ntawm kev qhwv ib ncig ntawm cov hlau ions nrog nws plaub pawg carboxyl thiab ob lub nitrogen atoms, tsim kom muaj kev sib koom ua ke octahedral uas ua tau zoo "locks tseg" reactive hlau.Cov txheej txheem chelation no yog dab tsi ua rau EDTA-2Na indispensable nyob rau hauv formulation chemistry. Lub Chaw Haujlwm Saib Xyuas Tshuaj European (ECHA Registration Dossier) faib nws nyob rau hauv EC Number 205-358-3 raws li ib tug mono-constituent organic tshuaj.

FAQ: Cov Lus Nug Txog EDTA-2Na

Puas yog EDTA-2Na muaj kev nyab xeeb rau siv hauv cov khoom siv tawv nqaij?

Yog lawm. CovCosmetic Ingredient Review Expert Panelxaus lus tias disodium EDTA muaj kev nyab xeeb raws li siv hauv cov tshuaj pleev ib ce. Cov kev kuaj mob tau pom tias qhov nqus ntawm daim tawv nqaij tsawg, thiab FDA tau pom zoo EDTA ntsev ua zaub mov preservatives, qhia txog lawv qhov kev ruaj ntseg profile.

Dab tsi yog qhov txawv ntawm EDTA-2Na thiab EDTA-4Na?

EDTA-2Na (disodium ntsev) muaj ob lub sodium atoms thiab tsim cov kua qaub me ntsis (pH 4–5), ua rau nws nyiam rau kev kho tawv nqaij. EDTA-4Na (tetrasodium ntsev) muaj plaub lub atoms sodium, tsim cov tshuaj alkaline (pH 10-11), thiab muaj zog chelation-zoo dua haum rau kev siv tshuaj ntxuav tu uas xav tau ntau dua pH ib puag ncig.

Qhov concentration ntawm EDTA-2Na kuv yuav tsum siv li cas hauv kuv cov qauv?

Hom tshuaj pleev ib ce muaj ntau yam ntawm 0.05% mus rau 0.5%, nyob ntawm seb cov khoom lag luam thiab dej hardness. Cov khoom siv xim plaub hau tuaj yeem siv txog li 3%. Pib ntawm 0.1% rau feem ntau tawm- ntawm cov khoom lag luam thiab kho raws li kev ntsuas kev ruaj ntseg. Ib txwm ua cov kev tshawb fawb nrawm nrawm ua ntej ua tiav koj cov qauv.

EDTA-2Na puas tuaj yeem siv rau hauv cov khoom noj khoom haus?

Yog, nyob rau hauv txoj cai txwv. FDA tso cai calcium disodium EDTA thiab disodium EDTA ua cov khoom noj ntxiv rau cov ntawv thov tshwj xeeb xws li taum taum, dej qab zib, zaub xam lav, thiab mayonnaise. Qhov siab tshaj plaws tso cai sib txawv ntawm cov khoom noj-feem ntau yog 25–500 ppm nyob ntawm daim ntawv thov.

Yam tsawg kawg nkaus kom muaj nuj nqis rau EDTA-2Na yog dab tsi?
