Modern consumer products are made from a host of starting materials and additives. Their manufacture involves complex chemical and physical processes. When undesired product properties arise, finding the cause can be a huge challenge. In order to identify off-odors we possess start-of-the-art analytical facilities and in-depth expertise in this area. Our detailed knowledge of material properties and reaction pathways for odorous substances is utilized to discover the causes and to develop avoidance strategies. The particular focus of our research is the identification of off-odors in raw materials, other materials, and everyday consumer products and the evaluation of pleasant, desired odors in materials.
