Toxicology and risk assessment
A.A. 2024/2025
Obiettivi formativi
The course is aimed at providing the specific knowledge about toxicology and risk assessment applied to the cosmetic field. The course will highlight the principles of cellular toxicity about skin, skin annexes and eye toxicology in terms of irritation, allergies, hypersensitivity, also related to daily exposure. Potential harmful effects of both natural and synthetic chemical compounds, used in the skincare formulations, make-up, and cleaning products will be analysed. Furthermore, the course will describe the tests used to evaluate the toxicity of cosmetics ingredient and the process of cosmetics risk assessment, divided in three steps: the hazard identification, the dose-response, and the exposure assessment.
Risultati apprendimento attesi
At the end of the course the students will be able to:
- Describe with proper terminology the mechanisms of cell toxicity potentially induced by cosmetics;
- Describe the ingredients in cosmetics associated to their potentially toxic profile;
- Identify the most appropriate tests to be used to evaluate skin and eye toxicity;
- Describe the process of safety assessment process of cosmetic ingredients;
- Perform basic assays to evaluate cell toxicity and to interpret the results;
- Evaluate and analyse the risk assessment case studies.

Prerequisiti
None
Metodi didattici
Frontal classes with slides, video support, and expert lessons. Laboratory experiences based on in vitro toxicity assays will be performed in the Toxicology module. In the Risk assessment module, the students will discuss case-studies and risk communication/management through power point presentations.
Materiale di riferimento
Slides presented during the classes, digital supplemental material, scientific papers (available on the ARIEL website).
Modalità di verifica dell’apprendimento e criteri di valutazione
The exam consists in a multiple-choice test with 16 questions in 1 hour: 2 points for every correct answer, 0 points for unanswered/not correct answer. The exam is passed with a minimal score of 18.
