The objective of this study is to determine the role of surfactants in flotation deinking through the use of their HLB factors. As an aside a comparison of surfactant and a product called Serfax NP-10 was made along with a study looking at the effect of surfactants and Serfax on a closed water system. It was found that an HLB of 13.5 worked best for flotation deinking and this points to the conclusion that the surfactant is working as a detergent. The Serfax product seemed to work as well as the best surfactant without any detrimental results in the closed water system. The brightness seemed to go down when the surfactant was used in the closed water system.
