Hydrophilic Cationic Silicone Softener KR-550 for Textile Finishing
KR-550 is a liquid textile softener positioned for hydrophilic, soft, and smooth handle finishing on cotton, polyester, and blended fabrics. Overseas buyers should verify the exact active content, silicone chemistry, pH range, ionic character, appearance, Oeko-Tex documentation, HS classification, drum packing, and export document readiness before RFQ confirmation.

Sourcing options
Request factory-direct quotation from Qingdao Kerun Bio-Technology Co., Ltd.
Ask for sample shipment before bulk order confirmation
Compare KR-550 with KR-516 and KR-518 if different hydrophilicity or softness balance is required
Source by drum packing for trial order, then negotiate container quantity for repeat shipment
Use Bangladesh office or local support channel if available for technical and delivery coordination

Compliance notes
Request SDS, COA, TDS, packing list, commercial invoice, certificate of origin, and any Oeko-Tex or textile compliance documents claimed
Confirm whether the product is classified as dangerous goods for sea or air shipment, including UN number, packing group, and transport hazard class if applicable
Verify destination-specific textile chemical restrictions for Bangladesh buyers, including buyer RSL/MRSL requirements where relevant
Ask supplier to confirm CAS identifiers or chemical family disclosure where available, especially for silicone softener components and preservatives
Do not rely on marketplace certification labels alone; request current, batch-relevant documents from the manufacturer or exporter
