Our range of optical brightness agents (OBAs) was specially developed to target specific fabric types. Broadly, we distinguish agents for cellulosic fibres like cotton and synthetic fibres like polyamide. They absorb light and re-emit it so that the colour tone of the treated textiles appears brighter. The whitening effect of our optical brightness agents is long-lasting, meaning they extend the quality of your textiles in terms of brightness and cleanliness factor.
