Optical Brightener FP-127 CAS 40470-68-6 for Plastics, PVC, Coatings and Inks
Optical Brightener FP-127 is a fluorescent whitening additive candidate for buyers sourcing materials for polymers, PVC, coatings, printing inks, synthetic fibers and artificial leather. Buyer verification should focus on CAS 40470-68-6, C.I. designation, assay or active content, appearance, shade, fluorescence strength, particle size, moisture, ash, melting range, insoluble matter, and application-specific compatibility. The listing indicates yellow powder, formula C30H26O2, EINECS 254-935-6, HS code 3204200000, 25 kg bag packing, China origin, and monthly production capacity claims that should be confirmed by supplier documents and pre-shipment testing.

Package and route
Packing notes
Listed transport package: 25 kg per bag
Request pallet configuration, liner type, moisture barrier details and outer bag material
Confirm whether export packing is suitable for sea freight, air freight or multimodal shipment
Ask if sample packing is available for qualification testing and whether sample batch matches commercial production
Request labeling details including product name, CAS number, batch number, net weight, origin and any transport marks
Confirm container loading quantity, palletized versus non-palletized option and packaging photos before shipment
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Supplier comparison for FP-127 equivalent grades based on CAS, COA and performance testing
How we compare
Sourcing options
Request sample first for lab compatibility and shade comparison
Qualify by lot-specific COA and third-party testing before bulk purchase
Compare FP-127 grades by fluorescence strength, particle size, impurity limits and thermal suitability
Source in 25 kg bag packing for standard industrial trial or production use
Ask for OEM labeling only after compliance, specification and traceability documents are approved
Use escrow or secured payment only as a commercial risk-control tool, not as a substitute for technical qualification
Human review
Compliance notes
Request current SDS, COA, TDS and product specification sheet before RFQ confirmation
Confirm dangerous goods status with supplier SDS and freight forwarder; do not rely only on marketplace text
Verify destination-market requirements for fluorescent whitening agents used in plastics, coatings, inks, textiles or leather applications
For food-contact, toy, cosmetic, medical, or regulated consumer-product use, request specific compliance declarations and conduct independent review before purchase
Confirm impurity profile expectations, including heavy metals, residual solvents, PAHs or other restricted substances where relevant to the end market
Ask whether the material is registered or notified where required for the buyer’s jurisdiction; supplier statements should be supported by documents
Importers should validate HS code, customs description, labeling and transport classification with qualified brokers or compliance teams
No regulatory approval or unrestricted-use guarantee should be assumed from the listing
