Mawu Oyamba

Sudan B ndi utoto wopangidwa ndi organic wokhala ndi dzina lamankhwala Sauermann Red G. Ndiwo gulu la azo la utoto ndipo uli ndi lalanje-wofiira wa crystalline powdery powdery.

 

Sudan B imakhala pafupifupi yosasungunuka m'madzi, koma imakhala ndi kusungunuka kwabwino mu zosungunulira za organic. Ili ndi kupepuka kwabwino komanso kukana chithupsa ndipo imatha kugwiritsidwa ntchito kuyika zinthu monga nsalu, mapepala, zikopa ndi mapulasitiki.

 

Njira yokonzekera Sudan B ndi yosavuta, ndipo njira yodziwika bwino ndiyo kugwiritsira ntchito dinitronaphthalene ndi 2-aminobenzaldehyde, ndikupeza zinthu zoyera pogwiritsa ntchito njira monga kuchepetsa ndi kukonzanso.

 

Ngakhale kuti Sudan B imagwiritsidwa ntchito kwambiri pamakampani opaka utoto, imakhala yapoizoni komanso yoyambitsa khansa. Kudya kwambiri kwa Sudan B kumatha kuwononga thupi la munthu, monga poizoni pachiwindi ndi impso.
