Fluorescent Brightener 191

Description:

Fluorescent Brightener 191, also known by its CAS number 12270-53-0, is a synthetic organic compound commonly used as a fluorescent whitening agent. It belongs to the class of stilbene derivatives and is characterized by its ability to absorb ultraviolet light and re-emit it as visible blue light, enhancing the brightness and whiteness of materials such as textiles, paper, and plastics. This compound is particularly effective in improving the appearance of fabrics by counteracting yellowing and providing a more vibrant look. Fluorescent Brightener 191 is soluble in organic solvents and has a relatively high melting point, making it stable under various processing conditions. Its application is widespread in the textile industry, where it is often incorporated into detergents and fabric softeners. However, it is essential to handle this chemical with care, as it may pose environmental concerns and potential health risks if not managed properly. Overall, Fluorescent Brightener 191 plays a significant role in enhancing the aesthetic qualities of consumer products.
