On request from: European Commission
SCCS Number: SCCS/1630/21
Adopted on: 24-25 June 2021

Conclusion of the opinion:

(1) In view of the above, and taking into account the scientific data provided, does the SCCS consider the nanomaterials A (Platinum and Colloidal Platinum ) and B (Acetyl tetrapeptide-17 (and) Colloidal Platinum) are safe when used in leave-on cosmetic products according to the maximum concentrations and specifications reported in the attached list, taking into account reasonably foreseeable exposure conditions?

Having considered all the information provided by the Notifiers, and that obtained from other sources, the SCCS is of the opinion that it is not possible to carry out a safety assessment of any of the notified platinum nanomaterials due to limited or missing essential information. The limited amount of data provided by the Notifiers also does not correspond to the requirements and data standards as indicated in the SCCS Guidance (SCCS 1611/19), and the SCCS Memorandum (SCCS/1524/13).

To enable safety assessment by the SCCS, the Notifiers need to provide the necessary information, a summary of which is provided in Annex I.

(2) Does the SCCS have any further scientific concerns with regard to the use of materials A and B in nano form in cosmetic products?

In the absence of sufficient data to allow safety assessment, the SCCS has considered the different aspects of platinum nanomaterials that could raise a concern over consumer safety. As detailed in Annex II, the SCCS has concluded that there is a basis for concern that the use of platinum, colloidal platinum, and acetyl tetrapeptide-17 colloidal platinum (nano) in cosmetic products can pose a risk to the consumer. The SCCS will be ready to assess any evidence provided to support safe use of the materials in cosmetic products.
