There are serious toxicological concerns surrounding nano-particles in consumer products including potential genotoxicity, carcinogenicity, reproductive toxicity, and photo-induced toxicity. Both materials were found to have insufficient or flawed testing data, with no studies submitted on systemic absorption or long-term health effects. Regulatory guidelines from SCCS were not followed, and many applicants relied on irrelevant industrial standards or unsupported safety claims. Critical data was missing in every health category, including toxicokinetics, human exposure, and safety margins. This lack of compliance, combined with misleading or incomplete manufacturer claims, highlights significant regulatory gaps and a troubling lack of transparency in assessing the safety of these nanomaterials.
