    Abstract: The present disclosure related to a method of producing a color stable, light colored lignin. The method includes: reacting a lignin composition with a hypochlorite composition having about 5% to about 70% available chlorine; and reacting the hypochlorite treated lignin with hydrogen peroxide at a concentration of about 5% to about 50% to produce the light colored lignin, wherein the lignin composition includes at least one of sulfonated lignin, lignosulfonate, or both.

    Abstract: Presently described are methods for performing rosin purification. The methods described herein utilize a unique solvent precipitation process that surprisingly and unexpectedly reduces the color of rosin and the sulfur and unsaponifiable contents in the rosin. The described methods are also applicable to rosin derivatives such as rosin esters and amides. Utilizing this purified rosin as raw material, rosin derivatives with much improved characteristics (color, softening point and sulfur content) can be made that would otherwise be difficult to make.
