- a lignosulfonate or a kraft lignin;
- an alkaline compound;
- optionally an additive;
- and
- a plurality of substrates,
- wherein the blended furnish has a buffer capacity of 2-200 mL of 0.1 N HCl by the Acid Titration Value (ATV) Method using 20 grams of blended furnish for a period of time up to 20 days.
