Usage

General Description

Fluorescent Brightener ER-III is a chemical compound belonging to the fluorescent brightener family, commonly used in the textile industry to improve the brightness and whiteness of fabrics. It works by absorbing ultraviolet light and emitting blue light, which makes the treated material appear whiter and more vibrant. Fluorescent Brightener ER-III is also employed as a brightening agent in detergents and other cleaning products, where it enhances the visual appearance of fabrics by counteracting the yellowing effects of aging and repeated washing. This chemical is known for its ability to make colors appear more intense and to give a fresh, bright look to textiles in various applications.
