The European Commission requested this opinion following the notification, under Article 16 of Regulation 1223/2009, of 63 cosmetic products containing it. It has been adopted during the plenary meeting of 21-22 February 2018, and is opened to comments until 15 May 2018.
This Opinion has been adopted in its final version during the plenary meeting of the SCCS on 24-25 October 2018
The Commission received 63 notifications of cosmetic products containing Colloidal Silver (CAS No7440-22-4, EC No231-131-3) in nano form, as reported in the attached list.

The Commission has concerns on the use of Colloidal Silver in nano form because of the potential for nanoparticles to be absorbed and enter into the cells.
