On 26 October 2018, the European Commission (EC) Scientific Committee on Consumer Safety (SCCS) published its final opinion on colloidal silver (nano). According to the final opinion, the EC received 63 notifications of cosmetic products containing colloidal silver in nano form. The final opinion states that, according to the applicants, the ingredient is used in nano uncoated form both in leave-on and rinse-off oral cosmetics products, including toothpastes and skin care products, with a maximum reported concentration limit of one percent and certain specifications. The EC asked SCCS to produce a safety assessment of the nano form of colloidal silver covered in the notifications, in the above-mentioned categories of products, taking into account the reasonably foreseeable exposure conditions. According to SCCS, only a limited amount of data was provided by the applicants that corresponded to the SCCS Guidance on Safety Assessment of Nanomaterials in Cosmetics (SCCS 1484/12). The provided data were also not in line with the SCCS Memorandum on Relevance, Adequacy and Quality of Data in Safety Dossiers on Nanomaterials (SCCS/1524/13). SCCS states that although other information is available in open literature relating to the toxicity of nano silver, its relevance with respect to the materials of this submission has not been considered by the applicants. Due to a number of major data gaps, SCCS is not in the position to draw a conclusion on the safety of colloidal silver in nano form when used in oral and dermal cosmetic products. The EC also asked SCCS to address any further scientific concerns with regard to the use of colloidal silver in nano form in cosmetic products. SCCS concluded that in addition to the safety assessment of colloidal silver in nano form, consideration should also be given to the likely presence of ionic silver in different types of final products.
