Why It Matters
Design pairs optical brighteners with chelants so fluorescent whitening agents deposit on fabric without metal-ion quenching
Solution Approach
Design pairs optical brighteners with chelants so fluorescent whitening agents deposit on fabric without metal-ion quenching RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (4)
Bis--stilbene Disulfonic Derivative
CAS 16090-02-1
Specialty Additives
Color / Pigmentation
Stilbene fluorescent whitening agent: absorbs UV and re-emits blue light, masking yellowing so white fabric reads brighter
