Azurant optique (OBA)

Optical Brightening Agent (OBA) is a chemical additive used to enhance the whiteness and brightness of textiles. It works by absorbing UV light and re-emitting it as visible blue light, making fabrics appear brighter. OBAs are widely utilized in the textile industry for their ability to improve the visual appearance of white or light-colored materials. They are also appreciated for their effectiveness at low concentrations and compatibility with various textile processing methods.
