Abakozi bashya bagaragaza bashoboye gukuramo urumuri UV kandi bakayitekereza mubururu na cyan bigaragara ko itara ry'umuhondo rito ku mwenda ariko nazo zongera umucyo. Kubwibyo, ongeraho ibikoresho bya Oba birashobora gutuma ibishishwa bireba byera abandi bakomeye.
Kubicuruzwa ubwabyo, hiyongereyeho Oba irashobora kunoza cyane umweru nubwiza bwo kumesa, isabune, nibindi, Kuzamura UwitekaIr isura, kandi ukore ibicuruzwa bisa neza kandi bifite isuku.
Ibikurikira ni ibintu bisanzwe byo kumesa:
| Ibirimo | Igipimo |
| Las | 15-20% |
| Na2CO3 | 20-30% |
| Na2O · nsio2 | 5-10% |
| 2Na2CO3· 3h2O | 5-10% |
| Ibyiza bya Optique | 0.1-0.5% |
| Ishingiro ryiza | 0.1-0.3% |
| Enzyme | 0.5-1% |
Ibyiza bya OptiqueCBS-X.zitangwa na sosiyete yacu iragereranywa rwose nikirango kizwi cyane cyu Burayi, mugihe igiciro cyacyo kizaba cyo hasi. Ikoreshwa cyane cyane murwego rwo hejurukumesa amazi, kandi irashobora kandi gukoreshwa byera cyangwa ibaraIsabune y'Ubwiza. Kubitekerezo byafatiwe, turatanga kandi iherezo ryo hasiibicuruzwa cyane cyaneIfu yo gukumira.
Ku bijyanye n'umutekano wa Oba, ubushakashatsi bwinshi bwuburozi haba mu gihugu ndetse no ku rwego mpuzamahanga bwerekanye ko OBA idafite karcinigenity, kwangumenintity, cyangwa teratogenentity. Kurugero, amashyirahamwe nka minisiteri yubudage, ishyirahamwe ryibidukikije ryibidukikije (AISE), hamwe nubutaka bwa jujiya (JSda) byakoze ishyirahamwe ryuzuye rya Oba, ryemeza ko ntangarugero kubantu nibidukikije.
Kubwibyo, ubu nta bushakashatsi buke bugaragaza ko OBA ari karcinogenic. Nubwo bamwe bavuga ko bishobora gutera uburakari cyangwa ibisubizo bya allergique kuruhu, ibi bitekerezo ntibijyanye na karcinigenity kandi bifite ibyago bike cyane.
