| lignin |
A naturally occurring component in plants. It is responsible for their strength, but it also causes paper to turn yellow and become brittle. It breaks down and forms acids that weaken the paper fibers. Paper that is lignin free will stay looking younger and stronger for longer. To be considered lignin-free, paper can be no more than 1% lignin.

The noncarbohydrate portion of the cell wall of plants. It is removed from wood fiber during the pulp manufacturing process, leaving cellulose for papermaking. Lignin by-products have found important uses as dispersing agents, oil well drilling mud additives and as a commercial source of vanillin.

Lignin is a polymer of three closely-related phenylpropane moieties. Unlike cellulose and hemicellulose, lignin cannot be depolymerized by hydrolysis. Cleavage of the principal bonds in lignin require oxidation.
