Optical Brightners

BERBRIGHT® 400 

(Technical Data) - is a tetrasulfonated anionic optical brightener (OBA) that is recommended for use in the manufacture of paper products.  It is generally suitable for all methods of application in both alkaline and acid papermaking systems. Formost grades of paper, this OBA chemistry is the most economical choice for brightening and whitening the sheet.

BERBRIGHT® 600

(Technical Data) - is a hexasulfonated anionic optical brightener (OBA) that is recommended for use in the manufacture of paper products with high brightness. It is generally suitable for all methods of application in both alkaline and acid papermaking systems. This OBA chemistry can be used at higher concentrations versus Berbright 400 without “greening” the paper sheet.
