Optical Brightening Agents muaj peev xwm nqus tau UV lub teeb thiab xav txog nws mus rau hauv xiav thiab cyan pom lub teeb, uas tsis tsuas yog cuam tshuam lub teeb daj me ntsis ntawm cov ntaub tab sis kuj ua rau nws ci ntsa iab. Yog li, ntxiv OBA cov tshuaj ntxuav tes tuaj yeem ua rau cov khoom ntxuav kom zoo nkauj thiab muaj zog dua.
Rau cov khoom lawv tus kheej, qhov sib ntxiv ntawm OBA tuaj yeem txhim kho cov xim dawb thiab ci ntsa iab ntawm cov ntxhua khaub ncaws, xab npum, thiab lwm yam.ir tsos, thiab ua kom cov khoom zoo dua high-end thiab huv si.
Cov hauv qab no yog ib qho qauv ntxhua khaub ncaws zoo li no:
| Cov ntsiab lus | Loj |
| LAS | 15-20% |
| Na2CO3 | 20-30% |
| Na2O·nSiO2 | 5-10% |
| 2 Naj2CO3· 3 H2O | 5-10% |
| Kho qhov muag Brightener | 0.1-0.5% |
| Aromatic Essence | 0.1-0.3% |
| Enzyme | 0.5-1% |
Lub optical brightenerCBS-Xmuab los ntawm peb lub tuam txhab yog kiag li piv rau ib tug zoo-paub European hom, thaum nws tus nqi yuav qis dua. Nws yog tsuas yog siv nyob rau hauv high-kawgntxhua khaub ncaws detergent kua, thiab tseem tuaj yeem siv rau cov xim dawb lossis ximxab npum zoo nkauj. Rau cov nqi txiav txim siab, peb kuj muab cov nqi qis kawgcov khoom feem ntau yog rauxab npum hmoov.
Hais txog kev nyab xeeb ntawm OBA, ntau yam kev tshawb fawb toxicological ob leeg hauv tsev thiab thoob ntiaj teb tau pom tias OBA tsis muaj carcinogenicity, mutagenicity, lossis teratogenicity. Piv txwv li, cov koom haum xws li German Ministry of Environment, European Union Detergent Association (AISE), thiab Nyiv Soap thiab Detergent Industry Association (JSDA) tau ua qhov kev ntsuam xyuas dav dav ntawm OBA, lees paub tias nws tsis muaj kev phom sij rau tib neeg thiab ib puag ncig ntawm kev siv tshuaj.
Yog li, tam sim no tsis muaj kev tshawb fawb pov thawj tias OBA yog carcinogenic. Txawm hais tias qee qhov sib cav tias nws tuaj yeem ua rau khaus lossis ua xua rau ntawm daim tawv nqaij, cov tshuaj tiv thaiv no tsis cuam tshuam rau carcinogenicity thiab muaj qhov tshwm sim tsawg heev.
