Application of silver-based biocides in face masks intended for general use requires regulatory control
the applications of silver-based biocides and for the implementation of regulatory standards, quality control and product development based on the safe-by-design principle for nanotechnology ...
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.
standardized and validated methodologies to characterize representative samples of 15 pristine E171 materials based on transmission electron microscopy (TEM) and single-particle inductively coupled plasma mass ...
Estimation of the Uncertainties Related to the Measurement of the Size and Quantities of Individual Silver Nanoparticles in Confectionery.
