Evaluation of the Antifoaming Effect Using Hansen Solubility Parameters …

11/3/2020· The Hansen solubility sphere method was used to measure the HSPs of antifoaming agents and a foam-forming surfactant. Various antifoaming agents were added to a surfactant solution, and the defoaming effect was evaluated. Correlations of 0.953–0.860 confirmed a relationship between affinity of the antifoaming agents for the surfactant based
