What Is Liquid Sulfonated Lignin? Lignin is a complex, three-dimensional polymer that provides structural support in plants. In its natural state, it’s largely insoluble in water, which limits its practical use. Sulfonation, typically performed during the sulfite pulping process, chemically alters lignin by attaching sulfonate groups, which are negatively charged and hydrophilic (water-attracting). This modification […]
