Abstract
The product design framework for systematic screening & selection of surfactants consists of four main steps: problem definition, target properties specification, data collection & model development, and screening-selection. The Hydrophilic-Lipophilic Deviation (HLD) value has been identified as the main target property because it is related to the microemulsion type of a surfactant-oil-water system. That is, when the HLD value is zero, the middle-phase microemulsion, which has the lowest interfacial tension of oil and water, is formed. The model for HLD estimation needs a parameter Cc, which is predicted by a group-contribution technique. The developed group-contribution model for anionic surfactants gives relative error equal to 3.5, while the model for non-ionic surfactants does not give very good relative error, mainly because of small values of Cc and not enough data. Nevertheless, the model for non-ionic surfactants is found to be qualitatively correct and so it can be used for surfactant screening-selection. Other properties like melting point, cloud-point, etc., are also used for the screening-selection step. Application of the model-based method is highlighted through two case studies, where the results have been verified experimentally.
