Sap Brown

Sap brown and sap brown in flakes is an alkaline extraction of Cassel brown. Sap brown has a much better light fastness in contrast to Cassel brown and is used as colouring matter in the paper industry for manufacturing cardboard packaging and to some extent also in the pharmaceutical industry as well as in shoe soles and drilling fluids.
