Characteristics Of Fluorescent Brighteners

The main characteristics of fluorescent brighteners include:
Whiteness enhancement: Fluorescent brighteners can make products look whiter and brighter, thus improving the visual appeal of the product. This is particularly common in paper, fabric and plastic products.
Colorlessness: Fluorescent brighteners are usually colorless, so they do not change the original color of the product.
UV reflection: Fluorescent brighteners achieve their whitening effect by absorbing UV light and emitting visible light, which makes them particularly effective in daylight because they can reflect more visible light and make objects look whiter.
Blue light effect: The blue light of fluorescent brighteners reduces the yellowness of the substrate and gives a bright appearance. Unlike bleaching, it does not leave a yellowish tint, but instead presents a more pleasing appearance than white.
Lightfastness and chlorine bleaching resistance: Some fluorescent brighteners have good lightfastness and chlorine bleaching resistance, such as fluorescent brightener DT, which performs well in acidic environments with a pH value of 2-3 and alkaline environments with a pH value of 10.
