Fluorescent Brightener 230

Fluorescent Brightener 230 (CAS 27344-06-5), also referred to commercially as Fluorescent Brightener, is a stilbene-based optical brightening agent that absorbs ultraviolet light and re-emits it as visible blue-white fluorescence.

Applied to substrates that appear yellowed or dull, it corrects perceived color without bleaching, delivering a measurable whiteness improvement across textile, paper, and leather processing industries worldwide.

In textile finishing, it is applied to cotton, linen, and blended fabrics during dyeing or padding operations to achieve high whiteness indices required by apparel and home textile buyers.

Paper and pulp manufacturers incorporate it into surface sizing or coating formulations to meet brightness specifications for printing and writing grades. This ensures a high-quality finish for commercial paper products.

Leather processors use it in finishing baths to enhance the visual brightness of white and light-colored hides destined for footwear and upholstery markets. It provides a clean, professional aesthetic to the final leather goods.

It also performs in detergent formulations where fabric whitening during laundering is a required end-product claim. This versatility makes it a staple component in many industrial and consumer cleaning products.

Fluorescent Brightener 230 is supplied as a liquid solution or powder, with liquid concentrations being the most common commercial form for ease of dosing in continuous processing lines.

Standard supply grades are aligned with textile and industrial specifications, with purity levels and active content documented for quality assurance. Packaging is typically available in drums or IBCs for bulk procurement.
