The Scientific Committee on Consumer Safety (SCCS) has recently published the second revision of its guidance on the safety assessment of nanomaterials in cosmetics. The updated guidance, adopted on June 6, 2023, aims to provide comprehensive and up-to-date information on the evaluation of nanomaterials used in cosmetic products.
This revision includes several notable changes. New sections have been introduced, covering various aspects such as solubility, dissolution rate, solubility in non-aqueous media, evidence for the absence of nanoparticles, dispersion, aspect ratio, uptake into blood cells, reproductive toxicity, and endocrine disruption. Additionally, the guidance now incorporates the European Commission's recommendation for defining nanomaterials, which was published in 2022.
To address safety concerns, the SCCS has included key triggers based on SCCS/1618/2020, providing a clearer understanding of potential risks associated with nanomaterials. Furthermore, the revision incorporates updated information from recent literature, ensuring that the guidance reflects the latest scientific findings. Notably, the section on read-across and grouping has also been revised.
