chrome free lignosulfonate CAS NO.39331-38-9

It is made as anion surfactant, firstly, by boiling waste calcium sulfite liquid with main raw material of northeast white pine, and then going through a series of fine manufacturing process, like concentration and exchange. It has hydrophile group, so when used, it should control the water using volume to achieve best effect.
