Optical Brightener VBL is recognized for its anionic nature and its characteristic cyan-purple fluorescent hue. This property allows it to absorb UV radiation and re-emit it as visible blue light, effectively counteracting yellowing and creating a perception of enhanced whiteness. This makes it invaluable in sectors like paper manufacturing, where it improves the brightness of paper, pulp, and coatings. For textile producers, it serves to brighten cotton, viscose, and synthetic fibers, enhancing the appearance of light-colored and printed fabrics. When looking to buy Fluorescent Whitening Agent 85, considering its performance and application suitability is key. We are a premier optical brightener VBL supplier China, offering this product at competitive prices.

The recommended dosage varies, but generally falls between 0.05% to 0.4% depending on the substrate and desired level of whiteness.
