Consultancy & Support on Microbial Protection of Products and Manufacturing Processes- Analysis and Evaluation of Biocide Systems (existing & alternative)- Safe & Legally Compliant Application of Biocide Systems- Expertise in Product Formulation and Manufacturing Process Optimization- Assessment of Plant Hygiene

The heritage Microbial Control Business was integrated into Lanxess MPP (Material Protection Products).• Technical Support to our tollers re. upscaling, production, special tests, reworks, cleaning procedures, product wheel, compatibility of materials of construction, optimisation of processes with the aim of production capacity increase etc. • Technical Support to internal groups such as quality assurance, product development & formulation, distribution, Regulatory etc. e.g. for special batch releases (quality waivers), raw material qualification, stability studies, chemical compositions, shelf life extensions, setting transport temperatures etc. • Managing the technical know-how of our business unit, including the drafting of comprehensive technical product documentation (technology packages).Achievements: • Saving substiantial amounts of money each year alone by guidance through complex reworks of failed batches (instead of material disposal).• Critical Support enabling the successful transfer of production to a new toller.

The heritage Microbial Control Business was acquired by IFF.• Technical Support to our tollers re. upscaling, production, reworks and root cause analysis of failed batches, special tests, cleaning procedures to minimize risk of cross contamination, optimisation of processes with the aim of production capacity increase, etc.• Technical Support to internal groups such as quality assurance, product development & formulation, distribution, Regulatory etc., e.g. for special batch releases (quality waivers), raw material qualification, stability studies, chemical compositions, shelf life extensions, transport temperatures etc.Achievements:• Critical technical support enabling the successful transfer of production of entire product portfolio from internal site to an external toller.• Saving substantial amounts of money each year alone by guidance through complex reworks of failed batches (instead of material disposal).

Dow Microbial Control was acquired by DuPont.• Formulation: Development and stabilisation of liquid and pasty biocidal formulations for microbial control (bacteria, yeast, fungi, algae) in finished products for all kinds of applications, e.g. for household and personal care, paint & coatings, water treatment, marine antifouling, metal working fluids, plastics, textiles etc.• Hands-on execution of stability studies, material compatibility testing (e.g. w.r.t. corrosion) and phys.-chem. analyses incl. HPLCAchievements:• guided the successful development and characterisation of 2 product formulations.• managed the dismantling and setting up of a fully equiped formulation lab.

The former Acima Business was integrated into Dow Microbial Control.• Formulation: Development and stabilisation of liquid and pasty biocidal formulations for microbial control (bacteria, yeast, fungi, algae) in finished products for all kinds of applications, e.g. for household and personal care, paint & coatings, water treatment, marine antifouling, metal working fluids, plastics, textiles etc. • Stability studies, material compatibility testing (e.g. w.r.t. corrosion) and phys.-chem. analyses incl. HPLC • Screening and identification of synergistic biocide combinations with/without booster with the help of an automated screening equipment (robot). and comprehensive patent analysis in the area of in-can preservation.• Raw material evaluation and Technical Support to production (upscaling, reworks), quality assurance etc.Achievements• managed the development and characterisation of 12+ formulated products commercialized successfully• achieved 4 granted patents and filed 2 patent applications

Buchs, St Gallen, Switzerland

Acima AG was acquired by Dow in 2009.I was supervisor of 3 lab technicians in the R&D lab.Similar job activities as in the sections described above (2013-2022).Achievements:• managed the development and characterisation of 13+ formulated products commercialized successfully• achieved 4 granted patents
