Request SDS →This disodium bis(triazinylamino)stilbene disulfonate (CAS 16090-02-1) is a stilbene-type fluorescent whitening agent. It is used predominantly in household detergents to whiten fabrics, and as a brightener and dye in the paper and textile industries. The molecule fluoresces under UV light to offset yellowing.
Frequently Asked Questions
What is this bis(triazinylamino)stilbene disulfonic derivative used for?
This disodium bis(triazinylamino)stilbene disulfonate (CAS 16090-02-1) is a stilbene-type fluorescent whitening agent. It is used predominantly as an optical brightener in household and heavy-duty laundry detergents, and as a brightener in the textile and paper industries.
How does an optical brightener like this work?
The molecule absorbs UV light and re-emits it as visible blue fluorescence, which offsets the natural yellowing of fabrics and fibers so they appear whiter. This is the basis for its use in detergents, cotton finishing, and pulp and paper.
What is the CAS number and HS classification for this brightener?
It is CAS 16090-02-1, molecular formula C40H38N12Na2O8S2. It classifies under HS 3204.20 (synthetic organic fluorescent brightening agents); we confirm the destination-specific code on the quote.
How is this optical brightener supplied in bulk and what is the MOQ?
We supply this stilbene brightener in bulk industrial packaging for detergent, textile, and paper manufacturers. Packaging, available form, and MOQ are confirmed per order; request a bulk quote with your target volume.
Can you provide a CoA and SDS for this fluorescent whitening agent?
Yes. A Certificate of Analysis and Safety Data Sheet are available with each shipment. Specify your application (detergent, textile, or paper) when requesting documentation so we route the appropriate grade.
