»Safe-by-design: Novel approaches for development of safe cosmetic spray products«

The ban on animal testing and increased requirements for inhalation exposure characterization have led to major challenges in the development and safety assessment of new cosmetic spray products. To support the industry, Fraunhofer ITEM has developed new methods for toxicological testing and exposure assessment aiming at an intrinsically safe design (Safe-by-design).

These methods include in-vitro inhalation testing to identify toxic substances, optimize ingredients and process conditions as well as estimate safety in humans during use by in vitro to in vivo correlation (QIVIVE). The approach is particularly useful for complex product compositions. In line with the safe-by-design approach, a methodology was developed that allows to minimize inhalation exposure to substances of concern.

Dr. Katharina Schwarz and Dr. Detlef Ritter will present case studies demonstrating the effectiveness of these integrated approaches to support the development of safe cosmetic spray products and risk assessment.

Speaker Spotlight: Dr. Katharina Schwarz

Dr. Katharina Schwarz is head of the department “Aerosol Technology and Aerosol Biophysics” at Fraunhofer ITEM.

She is an expert at the interface between aerosol and inhalation research, respiratory pharmacokinetics, toxicology and physiology, and inhalation exposure science with a special focus on particle lung dosimetry and biophysical particle-lung interactions. She is responsible for the aerosol aerosol/inhalation and dosimetry-related/QIVIVE-related aspects in drug development programs and toxicological or inhalation exposure studies including GLP/GCP-compliance. 

Customers are major pharmaceutical, chemical and cosmetic companies from Europe and US as well regulatory authorities. A particular focus is on exposure and safety assessment of (cosmetic) spray products incl. development of approaches for quantitative in-vitro to in-vivo extrapolations (QIVIVE) for respiratory toxicity and risk assessment.
