Periodic Report Summary 1 - ISSFLOW (Intelligent Structuring Systems for Complex Flowing Products)

ISSFLOW, Intelligent Structuring Systems for Complex Flowing Products, aims at developing fundamental understanding of complex fluids to allow for the design of smart and functional gels and fluids via the development of novel rheology modifiers. A consortium of 5 partners (1 large industry, 1 SME and 3 academics) has been set up to exchange knowledge in the areas of rheology, sustainable synthesis and scale-up of novel molecules, modeling, characterization of complex fluids (including high viscous fluids and gels) via scattering, NMR and microscopy techniques, and production of finished products in a broad number of applications ranging from detergents and pharmaceuticals to restoration of paintings and lubricants. The overall generated knowledge will be integrated in an overarching model that will be able to predict the best rheology modifier for a specific application, taking into account final rheology properties required, performance, process and aesthetics, facilitating the launch of improved or new products to the market.

During the first two years of the project, the team has collaborated in order to identify novel rheology modifiers that enable superior complex fluids. Over 100 molecules have been synthesized and tested, from which 2 lead candidates have been chosen:

• modified macromolecules that are able to form gels in hydrophobic systems and provide additional properties to the system
• Modified polymers that show high versatility among traditional formula ingredients but do not have the desired weight efficiency and therefore further optimization is required

While the design and synthesis of novel rheology modifiers is key, the development of methods and characterization tools to evaluate those rheology modifiers is equally important. With a special emphasis in rheology, the team has developed over 20 methodologies that allow the characterization of such rheology modifiers.

Meeting end application success criteria is key to bring lead technologies to the market. Some prototypes have been prepared and are currently under evaluation to further improve this technology.
Moreover, the team is actively working on the industrial feasibility and scale up of such rheology modifiers. There are two areas in which the team is actively working: a) scale-up of lead molecules; b) introduction of these molecules in desired products.
