Deinking Surfactant (Flotation Deinking)
Deinking surfactants are specialty blends of fatty acid soaps, nonionic, and anionic surfactants formulated to detach ink particles from recycled paper fibers and facilitate their removal by flotation or washing. Effective deinking surfactants improve brightness and cleanliness of deinked pulp (DIP), enabling production of high-quality recycled fiber papers. Formulations are optimized for different recovered paper grades including ONP, OMG, and mixed office waste.
