Evening lecture by Prof. Dr. Mariska Leeflang, organized by the 'Chemische Kring Zwolle'.

The architecture of modern dishwasher detergents: the path to bio-based and biodegradable. From zinc to amylase.

Summary
My name is Willem Vaneker; I am 33 years old, married and the father of a daughter, Fenna (1). In 2016, I obtained my Bachelor’s degree in Chemistry from Saxion University of Applied Sciences in Enschede. Prior to this degree, I worked in the production, quality control and development of industrial cleaning products. In addition to traditional chemistry, I also focused on the application of probiotics in cleaning products.

During my internship and final-year research project at my current employer, Dalli De Klok B.V., I further developed this specialisation. After spending a year working on the development of pharmaceutical tablets, I made the switch to the development of dishwasher tablets. At the former De Klok Soap Factory, approximately 40,000 tonnes of dishwasher tablets, capsules, powders and gels are developed and produced annually. Development focuses significantly on the themes of bio-based and biodegradable products.

In this presentation, we will explore the common formulations, development processes and underlying principles of modern dishwasher detergents. We will also discuss protein and enzyme quantification in the picogram range, as well as the extent to which the water-soluble coating of the tablet is biodegradable.

Invitees are very welcome.
