Optical Brightening Agents ifite ubushobozi bwo kwinjiza urumuri rwa UV no kukigaragaza mu mucyo ugaragara w'ubururu na cyan, ibyo bikaba bitarwanya gusa urumuri rw'umuhondo ruke ku mwenda ahubwo binongera ubwiza bwarwo. Kubwibyo, kongeramo ibikoresho bya OBA birashobora gutuma ibintu byogejwe bisa neza kandi bifite imbaraga.
Kubicuruzwa ubwabyo, kwiyongera kwa OBA birashobora kunoza cyane umweru nuburanga bwimyenda yo kumesa, isabune, nibindi, bitezimbereir igaragara, kandi itume ibicuruzwa bisa neza-birangiye kandi bisukuye.
Ibikurikira nuburyo busanzwe bwo kumesa:
| Ibirimo | Umubare |
| LAS | 15-20% |
| Na2CO3 | 20-30% |
| Na2O · nSiO2 | 5-10% |
| 2Na2CO3· 3H2O | 5-10% |
| Amashanyarazi meza | 0.1-0.5% |
| Ibyingenzi | 0.1-0.3% |
| Enzyme | 0.5-1% |
Amashanyarazi mezaCBS-Xitangwa nisosiyete yacu iragereranywa rwose nikirangantego kizwi cyane cyiburayi, mugihe igiciro cyacyo kizaba gito. Ikoreshwa cyane cyane murwego rwohejurukumesa, kandi irashobora no gukoreshwa cyera cyangwa ibaraisabune y'ubwiza. Kubitekerezo byigiciro, turatanga kandi amaherezo yo hasiibicuruzwa cyane cyane kuriifu yo kumesa.
Ku bijyanye n'umutekano wa OBA, ubushakashatsi bwinshi bw’uburozi haba mu gihugu ndetse no ku rwego mpuzamahanga bwerekanye ko OBA idafite kanseri, mutagenicite, cyangwa teratogenicity. Kurugero, amashyirahamwe nka minisiteri y’ibidukikije y’Ubudage, Umuryango w’ubumwe bw’ibihugu by’Uburayi (AISE), n’Urugaga rw’Ubuyapani Isabune n’Inganda (JSDA) bakoze isuzuma ryuzuye kuri OBA, bemeza ko bitagira ingaruka ku bantu no ku bidukikije ku kigero cyagenwe.
Kubwibyo, kuri ubu nta bushakashatsi bwemewe bwerekana ko OBA ari kanseri. Nubwo hari abavuga ko bishobora gutera uburakari cyangwa allergique ku ruhu, iyi myitwarire ntabwo ifitanye isano na kanseri kandi ifite ibyago bike cyane.
