Fluorescent Brightener 220(Cat No.:M078882), is a synthetic organic compound utilized as an optical brightener or fluorescent whitening agent (FWA). It is commonly employed in various industries, including textiles, paper, and plastics, to enhance the visual appearance of products by increasing their brightness and masking the yellowish or dull tones that can develop over time due to aging or exposure to light. Fluorescent Brightener 220 absorbs ultraviolet (UV) light and re-emits it as visible blue light, making treated materials appear whiter and brighter.
