Objectives: DC UK1 will develop non-aqueous models systems for filled colloidal gels that mimic the key features of UNILUK Deo anti-perspirants yet are amenable to detailed characterization (Rheo-confocal microscopy, DDM, cryo-SEM). In mapping the state behavior of these systems varying both the carrier fluid and particle properties, this work will build a framework for understanding more complex industrial formulations (UNILUK / Jamie) and inform computer simulations carried out at UU (de Graaf). This understanding will be transferred via industrial secondment at UNILUK, where high-throughput preparation and characterization platforms will enable rapid mapping of parameter space and validate testing/screening methods to identify shear-induced states in formulations. Model systems developed will also be used to test the role of ultrasound (CNRS) as a route to tune and control this state transition.
Industrial secondment: The DC will be at UNILUK (18M/M4-M12, M28-36) using model systems in high-throughput robotic formulation and rheological characterisation platforms.
