Abstract
This review paper collects the recent updates regarding the use of nanomaterials in cosmetics. Special focus is given to the applications of nanomaterials in the cosmetic industry, their unique features, as well as the advantages of nanoscale ingredients compared to non-nanoscale products. The state-of-the-art practices for physicochemical and toxicological characterization of nanomaterials are also reviewed. Moreover, special focus is given to the current regulations and safety assessments that are currently in place regarding the use of nanomaterials in cosmetics—the new 2019 European guidance for the safety assessment of nanomaterials in cosmetics, together with the new proposed methodologies for the toxicity evaluation of nanomaterials. Concerns over health risks have limited the further incorporation of nanomaterials in cosmetics, and since new nanomaterials may be used in the future by the cosmetic industry, a detailed characterization and risk assessment are needed to fulfill the standard safety requirements.
Highlights
Nanomaterials belong to a large “section” of materials, and their use has garnered great attention due to their significant physicochemical properties [1]
The use of nanomaterials (NMs) by the cosmetic industry aims for long-lasting effects and increased stability
Some of the main targets of using nanomaterials in cosmetics could be the efficient penetration into the skin for the improved delivery of the ingredients of the product, new color elements, transparency, and long-lasting effects (Figure 1)
Summary
Nanomaterials belong to a large “section” of materials, and their use has garnered great attention due to their significant physicochemical properties [1]. The purpose of this is for companies to offer end users adequate information regarding the safety of the products. 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 (REACH is a regulation of the European Union, and stands for Registration, Evaluation, Authorization, and Restriction of Chemicals). The types of nanomaterials that are currently used in cosmetics are discussed, followed by the recent status and advances regarding production and characterization of nanomaterials
