Description
4,4'-Bis(2-methoxystyryl)biphenyl is a stilbene-based optical brightening agent commercially known as CBS 127, Uvitex FP, and Brightener FP, with CAS number 40470-68-6 and EC number 254-935-6. It absorbs UV light and re-emits it as visible blue-white fluorescence, counteracting the yellowing effect in substrates.
In plastics and polymer processing, CBS 127 is incorporated during compounding to restore or enhance whiteness in polyolefins and engineering resins. In textile and paper applications, it is applied as a surface treatment agent, where its fluorescent emission corrects optical deficiencies caused by ageing or processing. It also functions as a UV stabilizer, reducing photodegradation in coatings and adhesive systems.
This compound is supplied as a powder and is registered under REACH. Procurement teams should confirm supplier-specific purity grades and documentation, including Safety Data Sheets aligned with EU GHS requirements. It is classified under HS code 3204200090 for customs and import purposes.
