STC3D - CONTROLLO DI QUALITA' DEI COSMETICI

The module provides both theoretical and practical foundations in cosmetic product quality control, offering a comprehensive framework starting with consumer safety in accordance with standards set by EU Regulation (EC) No 1223/2009, continuing through post‑marketing evaluation and monitoring, and covering rigorous laboratory testing and careful management of formulation, stability, and labeling. The following topics will be addressed:


Safety evaluation: toxicological data—including in silico or QSAR models for natural ingredients and impurities—and microbial stability.

Quality control, including sensory and rheological testing (texture, viscosity), chemical analyses (X‑ray, GC‑MS, LC‑MS for allergens and contaminants), and microbiological testing under ISO 11930 standards: preservative efficacy and water activity.

Regulated ingredients quality control as listed in Annexes II–VI: substances that are banned or restricted, including preservatives, UV filters, colorants, fragrance allergens (if > 0.001–0.01%), and contaminants such as heavy metals, nitrosamines, phthalates, formaldehyde, etc.

Microbiological quality control reference: ISO 11930 (2019 revision), the standard for evaluating antimicrobial protection.

Stability and packaging quality control: accelerated tests to simulate shelf life (temperature, light, humidity), checking packaging compatibility and substance migration. Determination of PAO (Period After Opening) or expiration date, with guidelines on optimal storage conditions.

Environmental monitoring of cosmetic ingredients.
