Description
Tinopal, also known as optical brighteners or fluorescent whitening agents, are chemical compounds used to enhance the appearance of textiles and paper. They absorb ultraviolet light and re-emit it as visible blue light, which can make fabrics and papers appear whiter and brighter.
In textiles, Tinopal is often added to laundry detergents to make whites appear whiter and colors brighter. It can also be used in paper manufacturing to improve the brightness and whiteness of paper products.
Tinopal is just one brand name for these types of optical brighteners, and there are many other similar products on the market under different brand names.
