TL;DR: A case by case toxicological evaluation is required taking into account that different clays have their own toxicological profiles, their modification can change this profile, and the potential increase of the human/environmental exposure to clay minerals due to their novel applications.

TL;DR: The aim of this work was to review the scientific publications, with a primary focus on the last 10 years, with respect to different in vitro toxicological aspects, mainly focussed on mutagenicity/genotoxicity of essential oils.

TL;DR: At lower concentrations, both compounds and their mixture were shown, for the first time, to protect cells against the damage induced by the H2O2.

TL;DR: Evaluated cytotoxicity of single wall CNTs functionalized with carboxylic acid on differentiated and non-differentiated Caco-2 cells, derived from a human intestinal adenocarcinoma indicated cytotoxic effects, which is necessary as the nanotechnology industry grows, and more nanoscale wastes are released into the environment.

TL;DR: In this article, the authors reviewed the scientific literature concerning these two properties together with the toxic effects induced by these substances on human cell lines, and established a safe range of concentrations for their use in active food packaging.
