Solvent Yellow 44 ua lauiloa foi o Sudan Yellow G i le kemisi, ma o lona fausaga vailaʻau o se chromate o Sudan Yellow G. O loʻo taua i lalo se faʻamatalaga i lona natura, faʻaoga, auala gaosiga ma faʻamatalaga saogalemu:

Tulaga lelei:

- Fa'aaliga: Solvent Yellow 44 o se pauta tioata mai moli-samasama i le mumu-samasama.

- Solubility: soluble i le vai, methanol, ethanol, insoluble i le eter, benzene ma isi solvents organic.

Fa'aaogā:

- Vainu'u vaila'au: solvent samasama 44 e mafai ona fa'aoga e fai ma vali i vali ma fa'ailoga reagents.

Metotia:

Ole solvent samasama 44 e masani lava ona saunia e ala ile tali ole sodium chromate ma Sudan samasama G ile vai vai.

Fa'amatalaga Saogalemu:

- Solvent Yellow 44 o se vaila'au vaila'au ma e tatau ona taulimaina ma le fa'aeteete e aloese mai le manavaina o le pefu po'o le fa'afeso'ota'i ma le pa'u, mata, ma isi.

- Fa'aaoga mea e puipui ai le tagata lava ia e pei o totigilima, mata tioata, ma lavalava puipui a'o fa'aoga.

- I le tulaga o le manava pe pa'i i le pa'u, fufulu vave i le tele o vai ma saili fesoasoani faafomai.

- I le taimi e teu ai, e tatau ona tu'u le solvent samasama 44 i se nofoaga mago, malulu, fa'alelei lelei ina ia 'alofia ai le fa'afeso'ota'i ma fa'amumu, mea fa'ama'i po'o isi mea e fa'agaoioia.

I se tulaga lautele, o le faʻaaogaina o le solvent samasama 44 e tatau ona faʻatinoina e tusa ai ma faiga faʻaogaina saogalemu ma e tusa ai ma le vaega faʻapitoa o talosaga ma manaʻoga faʻatonutonu.
