A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Fluorescent Brightener 113 (C.I. Fluorescent Brightener 113, CAS 12768-92-2) is a sulfonated stilbene-triazine optical brightening agent. It works by absorbing ultraviolet light and re-emitting it as visible blue fluorescence, masking the yellow cast of treated substrates.
Frequently Asked Questions
What are fluorescent brighteners?
Fluorescent brighteners (optical brightening agents) are additives that absorb ultraviolet light and re-emit it as visible blue fluorescence, masking the yellow cast of a substrate to make it appear whiter. Brightener BA-L is C.I. Fluorescent Brightener 113 (CAS 12768-92-2), a sulfonated stilbene-triazine type.
Is fluorescent brightener the same as bleach?
No. Bleach chemically removes or destroys colored compounds, while an optical brightener adds no whitening by chemistry; it works optically by converting absorbed UV into visible blue light. The two are often used together but function differently.
How does Fluorescent Brightener BA-L work?
It is a sulfonated stilbene-triazine optical brightener that absorbs UV and re-emits visible blue fluorescence, offsetting yellowness on compatible substrates. Performance depends on substrate compatibility and dosage.
What is the CAS number and HS code for Fluorescent Brightener BA-L?
It is C.I. Fluorescent Brightener 113, CAS 12768-92-2, classified under HS 3204.20 (synthetic organic products used as fluorescent brightening agents). Reference these on RFQs and customs paperwork.
What bulk packaging and documentation are available?
Supplied as an optical brightening agent for compatible substrate systems; request a bulk quote for available pack sizes and order quantities. An SDS and Certificate of Analysis accompany each shipment.
