Fluorescent Brightener 378 is widely used in the textile industry to enhance the brightness and whiteness of fabrics. It is applied during the manufacturing process to make white textiles appear more vibrant and to improve the color intensity of dyed fabrics. This chemical is also utilized in the production of paper and detergents, where it helps to achieve a brighter and cleaner appearance. Additionally, it finds application in plastics and coatings to improve visual appeal by adding a whitening effect. Its ability to absorb ultraviolet light and emit blue light makes it effective in counteracting the yellowish tint that can develop over time in various materials.
