Tall oil-based products During kraft pulping, extractives-based fats and waxes in the wood feedstock are saponified and converted into the sodium salts of fatty and resin acids.1 These sodium salts are removed as the main components of CTO soap during the evaporation process of the black liquor by skimming and are liberated by adding sulphuric acid
