The SCCS has just published its Opinion on the safety of two cosmetic ingredients in nano form: the Styrene/Acrylates copolymer [nano] and the Sodium styrene/Acrylates copolymer [nano]. It has been adopted during the plenary meeting of 21-22 February 2018, and is opened to comments until 11 May 2018.
Background
The Commission received 8 notifications of cosmetic products containing Styrene/Acrylates copolymer CAS No.9010-92-8, EC No.927-710-1 and Sodium styrene/Acrylates copolymer CAS No.9010-92-8 in nano forms.
These ingredients are reported in the CosIng database without any reference to the nano form with the function of film forming and opacifying, but they are not regulated under Cosmetic Regulation (EC) No.1223/2009.
The Commission has concerns on the use of Sodium styrene/Acrylates copolymer (nano) and Styrene/ acrylates copolymer (nano) because of the potential for nanoparticles to be absorbed and enter into the cells.

• Nanos: 2 requests for Opinion to SCCS of 7 September 2016
Opinion
1. In view of above, and taken into account the scientific data provided, the SCCS is requested to give its opinion on the safety of the nanomaterial Styrene/acrylates copolymer and Sodium styrene/Acrylates copolymer when used in leave-on cosmetics products with a maximum concentration limit of 0.06%, taking into account the reasonably foreseeable exposure conditions.
The SCCS has not been able to conclude on the safety of any of the three styrene/acrylate copolymer nano-entities submitted by the Applicants. The data submitted are insufficient to allow evaluation of possible toxicity. Regarding use it …
