PhD: Crystallisation of wax deodorant sticks

Cooling process can have a great impact on the crystalline wax materials. Although industry has significantly improved their products with advances of technology, the optimised physical properties of such a type of material are still difficult to control during the processes. This is due to the lack of fundamental understanding of crystallisation, such as crystal size, shape and polymorphs formed associated process conditions. Furthermore, shear rate also plays an important role during the process of wax crystallisation.
The project investigates fundamental aspects of wax crystallisation process to improve our understanding of relationship between process in terms of physical/chemical conditions and crystalline wax properties, in order for improvement of industrial processability.
