Ma Optical Brightening Agents amatha kuyamwa kuwala kwa UV ndikukupangitsani kukhala kuwala kwabuluu ndi kofiirira, komwe sikungolimbana ndi kuwala pang'ono kwachikasu pa nsalu komanso kumawonjezera kuwala kwake. Chifukwa chake, kuwonjezera sopo wa OBA kungapangitse zinthu zotsukidwa kuwoneka zoyera komanso zowala kwambiri.
Pazinthu zokha, kuwonjezera OBA kungathandize kwambiri kuyera ndi kuwala kwa sopo wochapira zovala, sopo, ndi zina zotero, komanso kungathandize kwambirimawonekedwe ake, ndipo zimapangitsa kuti zinthu zizioneka zapamwamba komanso zoyera.
Njira yodziwika bwino yotsukira zovala ndi iyi:
| Zamkati | Kuchuluka |
| LAS | 15-20% |
| Na2CO3 | 20-30% |
| Na2O·nSiO2 | 5-10% |
| 2Na2CO3·Maola 32O | 5-10% |
| Chowunikira Chowunikira | 0.1-0.5% |
| Fungo Lonunkhira | 0.1-0.3% |
| Enzyme | 0.5-1% |
Chowunikira cha kuwalaCBS-XKampani yathu imafanana kwambiri ndi kampani yodziwika bwino ku Europe, pomwe mtengo wake udzakhala wotsika. Imagwiritsidwa ntchito makamaka m'mafakitale apamwamba.sopo wochapira zovala, ndipo ingagwiritsidwenso ntchito pa zoyera kapena zamitundusopo wokongoletsaPakuganizira za mtengo, timaperekanso zinthu zochepazinthu makamaka zaufa wa sopo.
Ponena za chitetezo cha OBA, kafukufuku wambiri wa poizoni m'dziko muno komanso padziko lonse lapansi wasonyeza kuti OBA ilibe mphamvu ya khansa, kusintha kwa kagayidwe kachakudya, kapena teratogenicity. Mwachitsanzo, mabungwe monga Unduna wa Zachilengedwe ku Germany, European Union Detergent Association (AISE), ndi Japan Soap and Detergent Industry Association (JSDA) achita kafukufuku wokwanira wa OBA, kutsimikizira kuti ndi yopanda vuto kwa anthu ndi chilengedwe pa mlingo womwe waperekedwa.
Chifukwa chake, pakadali pano palibe kafukufuku wodalirika wotsimikizira kuti OBA imayambitsa khansa. Ngakhale ena amanena kuti ingayambitse kuyabwa kapena ziwengo pakhungu, izi sizikugwirizana ndi khansa ndipo zimakhala zochepa kwambiri.
