Optical Brightener KCB (C.I.367) is a synthetic fluorescent whitening agent supplied in powder form by Changsha Lianda Chemical Co., Ltd. The chemical is identified as a stilbene derivative with the colour index C.I. 367 and is listed under CAS No. 5089‑22‑5 and EINECS No. 225‑803‑5. The product is marketed for use in plastics, resins, films and textiles to improve brightness and whiteness. It is typically packed in fibre drums or multi‑layer paper bags for safe transport.
The brightener belongs to the class of stilbene‑based optical brighteners that absorb ultraviolet light and re‑emit it in the blue region, enhancing perceived colour. Typical purity levels for this grade exceed 98 %, with particle sizes below 100 µm and moisture content under 0.5 %. It is soluble at concentrations of about 0.5 % in water, allowing easy incorporation into polymer melts or textile dye baths. Such specifications are consistent with industry standards for high‑performance whitening agents.
Manufacturers of textile fibres, polymer extrusion plants and film converters commonly source KCB to achieve superior visual appeal in their end products. The supplier indicates flexible packaging options but does not state a minimum order quantity, so buyers should confirm any MOQ directly with Changsha Lianda Chemical. Trade conditions, incoterms and payment methods are not disclosed in the listing and must be agreed with the supplier before finalising the purchase.
