Nanomaterials 2020, 10, 979 8 of 16 consumers. The last updated catalogue consisted of 29 NMs. This catalogue is for consumer information, and it does not necessarily mean that all products listed in it are authorized NMs. Very recently (i.e., October 2019), the EC updated the existing guidance for nanomaterials in cosmetics with the Guidance on the Safety Assessment of Nanomaterials in Cosmetics, with the help of the SCCS (SCCS/1611/19). The SCCS provides guidance from industries to public authorities to ensure compliance with the EC No 1223/2009, regarding safety assessment of NMs intended for use as cosmetic ingredients. It should be noted that based on the Guidance SCCS/1484/12 from 2012, a complete animal testing ban has come in force under the Cosmetics Regulation since March 2013, and alternative methods for the safety assessment of cosmetic ingredients have been followed ever since (including NMs tests). In Europe, safety assessment is mandatory for all ingredients of cosmetic products. The same applies to nanomaterials to be used in cosmetics. In the EU, all cosmetic products, prior to being placed on the market, must be electronically communicated to the EC through the Cosmetic Products Notification Portal (CPNP), by the Responsible Person (i.e., designated legal or natural person of a company) for the purposes of market surveillance and for prompt and appropriate medical treatment. The information provided includes the identification of the NMs present in the cosmetic products. By the end of 2018, less than 1.5% of cosmetic products notified in the CPNP were declared to contain nanomaterials [81]. It is mandatory to declare whether the cosmetic product includes any NMs, under the Regulation (EC) No 1223/2009. Even if the NMs to be used are not described in the Regulation (most nano-based colorants, UV filters and preservatives are included) a special procedure should be followed. In case of concerns, the EC can ask the SCCS for further investigation [6]. The EC should authorize the nano-ingredients prior to their use in a cosmetic product. When it comes to the labeling, all NMs should be listed in the cosmetic label starting with the name of the chemical followed by the word (nano) in brackets. In the latest updated catalogue for NMs [82] in cosmetics, it is clearly stated that the catalogue is “for information only and is expressly not a list of authorised nanomaterials”. Until now, the EC has authorized the use of the following NMs: UV filters containing (nano) TiO2, ZnO, MBBT, and tris-biphenyl triazine. It has also allowed carbon black (nano) for use as a colorant in cosmetic products. The EC published a catalogue of all NMs that are used in cosmetic products in the EU in 2017, which was last updated on December 2019 (Table 1). It should be noted that many of the substances listed in Table 1 are also registered under the REACH Regulation. The nanomaterials guidance (NG) focuses on physicochemical characterization and exposure assessment of the materials, together with data requirements for human health risk evaluation based on the ingredients. Safety assessment of nanomaterials has been updated with a focus on immunotoxicity, encapsulated nanomaterials and nano-carriers. Moreover, new methodological approaches are presented for the toxicity evaluation of nanomaterials. In the beginning of 2020, The European Union Observatory for Nanomaterials (EUON) [15], announced that all companies that manufacture, use, or import nanoforms should have a REACH registration compliant. The purpose is for companies to give to end users adequate information needed for the safety of the products. This goes for all registrations of all nanoforms in the scope of REACH. NMs that fall within the scope of REACH and are not registered are considered illegal. Based on the recent catalogue of NMs, the EC asked the SCCS for a priority list of NMs for risk assessment. In the USA, the FDA monitors the use of NMs in cosmetics. In the FDA Nanotechnology Task Force Report of 2007 [83], the FDA presented an assessment of scientific and regulatory considerations relating to the safety and effectiveness of products containing NMs. The Task Force recommended the issue of a guidance describing safety issues for cosmetic products. Based on that, manufacturers should consider ensuring that cosmetic products made with NMs are safe. Still, there is no strict regulatory definition of nanotechnology and on NMs. In 2014, the FDA published a guidance for the industry titled “Final Guidance for Industry—Safety of Nanomaterials in Cosmetic Products” [14] which analyzes safety issues and provides guidance for cosmetic industries [55].PDF Image | Nanomaterials in Cosmetics: Recent Updates
