Mexican researchers sought to evaluate the effects of E171 across a span of conditions in mice, including its influence on behavior, along with the effects on the colon and liver. The research, published in 2020 in the journal Food and Chemical Toxicology, showed that E171 promoted anxiety and induced adenomas, or noncancerous tumors, in the colon. They also found that E171 heightened goblet cells hypertrophy and hyperplasia, which is typically seen in asthma patients and triggered by smoking or external pollutants and toxins. They also noted mucins overexpression in the mice, which can be linked to cancer cell formation.

Sustainability concerns are at the forefront of industrial developments, and TIO2 aligns seamlessly with green initiatives. Though traditionally produced through mining, advancements in synthetic production have mitigated environmental impacts. Furthermore, the photocatalytic nature of TIO2 allows it to interact with sunlight and facilitate the breakdown of organic pollutants on painted surfaces, contributing to cleaner environments.
