Background

The Commission received 172 notifications of cosmetic products containing the following nanomaterials: Silica (nano), Hydrated silica (nano), Silica silylate (nano), and Silica dimethyl silylate (nano).
The Commission has concerns on the use of silica in nano-form because of the potential high exposure in many types of products and because concerns have been raised regarding the potential for nanoparticles of silica to break out of the agglomerates and enter cells.
Therefore, the Commission would like to request the SCCS a safety assessment of the four types of nano silica covered in the notifications, in the above-mentioned categories of products, taking into account the reasonably foreseeable exposure conditions.
