    Fa'amatalaga o oloa:

    Pa'epa'e tioata pa'epa'e. Solu i le vai ma mafai ona chelate i le eseese o u'amea ions.

    Talosaga:

    (1) Faatasi ai ma masima o le EDTA, o le masima disodium e sili ona taua ma o se sui faʻalavelave taua mo le faʻalavelaveina o uʻamea uʻamea ma le vavaeeseina o metala, ae faʻapea foʻi mo vailaʻau, fasimoli vai, shampoos, vailaʻau vailaʻau faʻatoʻaga, bleaching ma faʻamautuina fofo mo le atinae ma le faagasologa o mea lanu-maaleale, vai faamamaina sooupu, pH adjusters, coagulants anionic, ma isi. I le faiga amata redox mo le polymerization o styrene-butadiene paʻu, disodium EDTA o loʻo faʻaaogaina e avea o se vaega o le sui malosi, aemaise lava mo le faʻalavelave. ion ferrous ma pulea le saoasaoa o tali polymerization. E maualalo le oona, fa'atasi ai ma le gutu LD50 o le 2000 mg/kg i isumu. Faʻaaogaina e fai ma sui chelating mo ion uʻamea.

    (2) Suʻesuʻeina le calcium, magnesium, ma isi. Faʻaaogaina i falemaʻi vailaʻau, atinaʻeina o lanu, faʻafefeteina o metala e le masani ai, ma isi. O se mea faʻalavelave faʻalavelave taua ma le faʻamalama uʻamea.

    (3) Faʻaaogaina e avea o se vailaʻau faʻalavelave ammonia carboxylate mo le fuafuaina o le calcium, magnesium ma isi metala. Faʻaaogaina e avea o se uʻamea faʻapipiʻi uʻamea ma faʻatupu lanu. Fa'aoga fo'i i totonu o fale talavai ma i le fa'afefiloi o u'amea e le masani ai.

    (4) E faʻaaogaina foi e avea o se antioxidant synergist i mea teuteu ma o se uʻamea chelating agent, lea e tutusa lona aafiaga e pei o le E DTA, ae o loʻo i ai se lautele lautele o talosaga. E mafai ona faʻaaogaina i mea teuteu mataʻutia o loʻo i ai ion uʻamea ma i le gaosiga ma le teuina ma le felauaiga o mea teuteu e faʻaogaina ai pusa uʻamea.

    afifi:25 kilokalama / taga poʻo e te manaʻo ai.

    Teuina:Teu i se nofoaga matutu, ea.
