IDENTIFICATION, PHYSICOCHEMICAL CHARACTERISATION AND PRELIMINARY RISK ANALYSIS OF TITANIUM DIOXIDE PARTICLES IN FACE MASKS Intermediate report TiO2-Mask COVID-19 project September 2021
safe to be used as a food additive because a concern for genotoxicity cannot be ruled out, it is advisable to issue precautionary standards to limit the presence of TiO2 particles in face masks. Health ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
Nanomaterials (Basel), Volume 10, Issue 3 (2020) Keywords: E171 food additive Single particle ICP-MS transmission electron microscopy Abstract: E171 (titanium dioxide) is a food additive that has been authorized ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
Single particle ICP-MS Abstract: E174 (silver) is a food additive that may contain silver nanoparticles (AgNP). Validated methods are needed to size and quantify these particles in a regulatory context. ...
