Additionally, the committee noted that the available data did not provide convincing evidence of genotoxicity for titanium dioxide as a food additive, but recognized the limitations in current methodologies with respect to the testing of poorly soluble particulate materials. Although there were uncertainties in the genotoxicity data, the experts took into account the fact that the additive was not carcinogenic in adequately conducted two-year studies in mice and rats at doses of up to 7,500 mg/kg BW per day for mice, and 2,500 mg/kg BW per day for rats, the highest doses tested. There was also no evidence of reproductive or developmental toxicity in studies in rats at doses up to 1,000 mg/kg BW per day, the highest doses tested.

  • Chemical resistance is another key property of R1930, making it suitable for use in a wide range of environments. It is resistant to acids, bases, and solvents, which means that it can withstand the conditions often encountered in printing processes. This makes R1930 an ideal choice for inks that will be used in harsh environments, such as outdoor signage or packaging materials that may come into contact with chemicals.
